+ * A cache that holds strong references to a limited number of values. Each time
+ * a value is accessed, it is moved to the head of a queue. When a value is
+ * added to a full cache, the value at the end of that queue is evicted and may
+ * become eligible for garbage collection.
+ *
+ * <p>If your cached values hold resources that need to be explicitly released,
+ * override {@link #entryRemoved}.
+ *
+ * <p>If a cache miss should be computed on demand for the corresponding keys,
+ * override {@link #create}. This simplifies the calling code, allowing it to
+ * assume a value will always be returned, even when there's a cache miss.
+ *
+ * <p>By default, the cache size is measured in the number of entries. Override
+ * {@link #sizeOf} to size the cache in different units. For example, this cache
+ * is limited to 4MiB of bitmaps:
+ * <pre> {@code
+ * int cacheSize = 4 * 1024 * 1024; // 4MiB
+ * LruCache<String, Bitmap> bitmapCache = new LruCache<String, Bitmap>(cacheSize) {
+ * protected int sizeOf(String key, Bitmap value) {
+ * return value.getByteCount();
+ * }
+ * }}</pre>
+ *
+ * <p>This class is thread-safe. Perform multiple cache operations atomically by
+ * synchronizing on the cache: <pre> {@code
+ * synchronized (cache) {
+ * if (cache.get(key) == null) {
+ * cache.put(key, value);
+ * }
+ * }}</pre>
+ *
+ * <p>This class does not allow null to be used as a key or value. A return
+ * value of null from {@link #get}, {@link #put} or {@link #remove} is
+ * unambiguous: the key was not in the cache.
+ *
+ * <p>This class appeared in Android 3.1 (Honeycomb MR1); it's available as part

+/**
+ * Manages native delegates.
+ *
+ * This is used in conjunction with layoublib_create: certain Android java classes are mere
+ * wrappers around a heavily native based implementation, and we need a way to run these classes
+ * in our Eclipse rendering framework without bringing all the native code from the Android
+ * platform.
+ *
+ * Thus we instruct layoutlib_create to modify the bytecode of these classes to replace their
+ * native methods by "delegate calls".
+ *
+ * For example, a native method android.graphics.Matrix.init(...) will actually become
+ * a call to android.graphics.Matrix_Delegate.init(...).
+ *
+ * The Android java classes that use native code uses an int (Java side) to reference native
+ * objects. This int is generally directly the pointer to the C structure counterpart.
+ * Typically a creation method will return such an int, and then this int will be passed later
+ * to a Java method to identify the C object to manipulate.
+ *
+ * Since we cannot use the Java object reference as the int directly, DelegateManager manages the
+ * int -> Delegate class link.
+ *
+ * Native methods usually always have the int as parameters. The first thing the delegate method
+ * will do is call {@link #getDelegate(int)} to get the Java object matching the int.
+ *
+ * Typical native init methods are returning a new int back to the Java class, so
+ * {@link #addNewDelegate(Object)} does the same.
+ *
+ * The JNI references are counted, so we do the same through a {@link WeakReference}. Because
+ * the Java object needs to count as a reference (even though it only holds an int), we use the
+ * following mechanism:
+ *
+ * - {@link #addNewDelegate(Object)} and {@link #removeJavaReferenceFor(int)} adds and removes
+ * the delegate to/from a list. This list hold the reference and prevents the GC from reclaiming
+ * the delegate.
+ *
+ * - {@link #addNewDelegate(Object)} also adds the delegate to a {@link SparseArray} that holds a
+ * {@link WeakReference} to the delegate. This allows the delegate to be deleted automatically
+ * when nothing references it. This means that any class that holds a delegate (except for the
+ * Java main class) must not use the int but the Delegate class instead. The integers must
+ * only be used in the API between the main Java class and the Delegate.
+ *
+ * @param <T> the delegate class to manage

+- Description -
+---------------
+
+Layoutlib_create generates a JAR library used by the Eclipse graphical layout editor
+to perform layout.
+
+
+- Usage -
+---------
+
+ ./layoutlib_create path/to/android.jar destination.jar
+
+
+- Design Overview -
+-------------------
+
+Layoutlib_create uses the "android.jar" containing all the Java code used by Android
+as generated by the Android build, right before the classes are converted to a DEX format.
+
+The Android JAR can't be used directly in Eclipse:
+- it contains references to native code (which we want to avoid in Eclipse),
+- some classes need to be overridden, for example all the drawing code that is
+ replaced by Java 2D calls in Eclipse.
+- some of the classes that need to be changed are final and/or we need access
+ to their private internal state.
+
+Consequently this tool:
+- parses the input JAR,
+- modifies some of the classes directly using some bytecode manipulation,
+- filters some packages and removes those we don't want in the output JAR,
+- injects some new classes,
+- generates a modified JAR file that is suitable for the Android plugin
+ for Eclipse to perform rendering.
+
+The ASM library is used to do the bytecode modification using its visitor pattern API.
+
+The layoutlib_create is *NOT* generic. There is no configuration file. Instead all the
+configuration is done in the main() method and the CreateInfo structure is expected to
+change with the Android platform as new classes are added, changed or removed.
+
+The resulting JAR is used by layoutlib_bridge (a.k.a. "the bridge"), also part of the
+platform, that provides all the necessary missing implementation for rendering graphics
+in Eclipse.
+
+
+
+- Implementation Notes -
+------------------------
+
+The tool works in two phases:
+- first analyze the input jar (AsmAnalyzer class)
+- then generate the output jar (AsmGenerator class),
+
+
+- Analyzer
+----------
+
+The goal of the analyzer is to create a graph of all the classes from the input JAR
+with their dependencies and then only keep the ones we want.
+
+To do that, the analyzer is created with a list of base classes to keep -- everything
+that derives from these is kept. Currently the one such class is android.view.View:
+since we want to render layouts, anything that is sort of a view needs to be kept.
+
+The analyzer is also given a list of class names to keep in the output.
+This is done using shell-like glob patterns that filter on the fully-qualified
+class names, for example "android.*.R**" ("*" does not matches dots whilst "**" does,
+and "." and "$" are interpreted as-is).
+In practice we almost but not quite request the inclusion of full packages.
+
+With this information, the analyzer parses the input zip to find all the classes.
+All classes deriving from the requested bases classes are kept.
+All classes which name matched the glob pattern are kept.
+The analysis then finds all the dependencies of the classes that are to be kept
+using an ASM visitor on the class, the field types, the method types and annotations types.
+Classes that belong to the current JRE are excluded.
+
+The output of the analyzer is a set of ASM ClassReader instances which are then
+fed to the generator.
+
+
+- Generator
+-----------
+
+The generator is constructed from a CreateInfo struct that acts as a config file
+and lists:
+- the classes to inject in the output JAR -- these classes are directly implemented
+ in layoutlib_create and will be used to interface with the renderer in Eclipse.
+- specific methods to override (see method stubs details below).
+- specific methods for which to delegate calls.
+- specific methods to remove based on their return type.
+- specific classes to rename.
+
+Each of these are specific strategies we use to be able to modify the Android code
+to fit within the Eclipse renderer. These strategies are explained beow.
+
+The core method of the generator is transform(): it takes an input ASM ClassReader
+and modifies it to produce a byte array suitable for the final JAR file.
+
+The first step of the transformation is changing the name of the class in case
+we requested the class to be renamed. This uses the RenameClassAdapter to also rename
+all inner classes and references in methods and types. Note that other classes are
+not transformed and keep referencing the original name.
+
+The TransformClassAdapter is then used to process the potentially renamed class.
+All protected or private classes are market as public.
+All classes are made non-final.
+Interfaces are left as-is.
+
+If a method has a return type that must be erased, the whole method is skipped.
+Methods are also changed from protected/private to public.
+The code of the methods is then kept as-is, except for native methods which are
+replaced by a stub. Methods that are to be overridden are also replaced by a stub.
+
+The transformed class is then fed through the DelegateClassAdapter to implement
+method delegates.
+
+Finally fields are also visited and changed from protected/private to public.
+
+
+- Method stubs
+--------------
+
+As indicated above, all native and overridden methods are replaced by a stub.
+We don't have the code to replace with in layoutlib_create.
+Instead the StubMethodAdapter replaces the code of the method by a call to
+OverrideMethod.invokeX(). When using the final JAR, the bridge can register
+listeners from these overridden method calls based on the method signatures.
+
+The listeners are currently pretty basic: we only pass the signature of the
+method being called, its caller object and a flag indicating whether the
+method was native. We do not currently provide the parameters. The listener
+can however specify the return value of the overridden method.
+
+This strategy is now obsolete and replaced by the method delegates.
+
+
+- Strategies
+------------
+
+We currently have 4 strategies to deal with overriding the rendering code
+and make it run in Eclipse. Most of these strategies are implemented hand-in-hand
+by the bridge (which runs in Eclipse) and the generator.
+
+
+1- Class Injection
+
+This is the easiest: we currently inject 4 classes, namely:
+- OverrideMethod and its associated MethodListener and MethodAdapter are used
+ to intercept calls to some specific methods that are stubbed out and change
+ their return value.
+- CreateInfo class, which configured the generator. Not used yet, but could
+ in theory help us track what the generator changed.
+
+
+2- Overriding methods
+
+As explained earlier, the creator doesn't have any replacement code for
+methods to override. Instead it removes the original code and replaces it
+by a call to a specific OveriddeMethod.invokeX(). The bridge then registers
+a listener on the method signature and can provide an implementation.
+
+This strategy is now obsolete and replaced by the method delegates.
+See strategy 5 below.
+
+
+3- Renaming classes
+
+This simply changes the name of a class in its definition, as well as all its
+references in internal inner classes and methods.
+Calls from other classes are not modified -- they keep referencing the original
+class name. This allows the bridge to literally replace an implementation.
+
+An example will make this easier: android.graphics.Paint is the main drawing
+class that we need to replace. To do so, the generator renames Paint to _original_Paint.
+Later the bridge provides its own replacement version of Paint which will be used
+by the rest of the Android stack. The replacement version of Paint can still use
+(either by inheritance or delegation) all the original non-native code of _original_Paint
+if it so desires.
+
+Some of the Android classes are basically wrappers over native objects and since
+we don't have the native code in Eclipse, we need to provide a full alternate
+implementation. Sub-classing doesn't work as some native methods are static and
+we don't control object creation.
+
+This won't rename/replace the inner static methods of a given class.
+
+
+4- Method erasure based on return type
+
+This is mostly an implementation detail of the bridge: in the Paint class
+mentioned above, some inner static classes are used to pass around
+attributes (e.g. FontMetrics, or the Style enum) and all the original implementation
+is native.
+
+In this case we have a strategy that tells the generator that anything returning, for
+example, the inner class Paint$Style in the Paint class should be discarded and the
+bridge will provide its own implementation.
+
+
+5- Method Delegates
+
+This strategy is used to override method implementations.
+Given a method SomeClass.MethodName(), 1 or 2 methods are generated:
+a- A copy of the original method named SomeClass.MethodName_Original().
+ The content is the original method as-is from the reader.
+ This step is omitted if the method is native, since it has no Java implementation.
+b- A brand new implementation of SomeClass.MethodName() which calls to a
+ non-existing static method named SomeClass_Delegate.MethodName().
+ The implementation of this 'delegate' method is done in layoutlib_brigde.
+
+The delegate method is a static method.
+If the original method is non-static, the delegate method receives the original 'this'
+as its first argument. If the original method is an inner non-static method, it also
+receives the inner 'this' as the second argument.

+ * The content is the original method as-is from the reader.
+ * This step is omitted if the method is native, since it has no Java implementation.
+ * <li> A brand new implementation of {@code SomeClass.MethodName()} which calls to a
+ * non-existing method named {@code SomeClass_Delegate.MethodName()}.
+ * The implementation of this 'delegate' method is done in layoutlib_brigde.
+ * </ul>
+ * A method visitor is generally constructed to generate a single method; however
+ * here we might want to generate one or two depending on the context. To achieve
+ * that, the visitor here generates the 'original' method and acts as a no-op if
+ * no such method exists (e.g. when the original is a native method).
+ * The delegate method is generated after the {@code visitEnd} of the original method
+ * or by having the class adapter <em>directly</em> call {@link #generateDelegateCode()}
+ * for native methods.
+ * <p/>
+ * When generating the 'delegate', the implementation generates a call to a class
+ * class named <code><className>_Delegate</code> with static methods matching
+ * the methods to be overridden here. The methods have the same return type.
+ * The argument type list is the same except the "this" reference is passed first
+ * for non-static methods.
+ * <p/>
+ * A new annotation is added to these 'delegate' methods so that we can easily find them
+ * for automated testing.
+ * <p/>
+ * This class isn't intended to be generic or reusable.
+ * It is called by {@link DelegateClassAdapter}, which takes care of properly initializing
+ * the two method writers for the original and the delegate class, as needed, with their
+ * expected names.
+ * <p/>
+ * The class adapter also takes care of calling {@link #generateDelegateCode()} directly for
+ * a native and use the visitor pattern for non-natives.
+ * Note that native methods have, by definition, no code so there's nothing a visitor
+ * can visit.
+ * <p/>
+ * Instances of this class are not re-usable.
+ * The class adapter creates a new instance for each method.
