Method Detail

analyzeClass

public MutableClass analyzeClass(byte[] origClassBytes,
                                 InstrumentationConfiguration config,
                                 ClassNodeProvider classNodeProvider)

instrument

public byte[] instrument(byte[] origBytes,
                         InstrumentationConfiguration config,
                         ClassNodeProvider classNodeProvider)

instrument

public void instrument(MutableClass mutableClass)

addDirectCallConstructor

protected abstract void addDirectCallConstructor(MutableClass mutableClass)

writeCallToInitializing

protected abstract void writeCallToInitializing(MutableClass mutableClass,
                                                org.robolectric.internal.bytecode.RobolectricGeneratorAdapter generator)

instrumentNormalMethod

protected void instrumentNormalMethod(MutableClass mutableClass,
                                      org.objectweb.asm.tree.MethodNode method)

Rename the method from methodName to $$robo$$methodName.

Make it private so we can invoke it directly without subclass overrides taking precedence.

Remove final and native modifiers, if present.

Create a delegator method named methodName which delegates to the ClassHandler.

interceptInvokeVirtualMethod

protected abstract void interceptInvokeVirtualMethod(MutableClass mutableClass,
                                                     java.util.ListIterator<org.objectweb.asm.tree.AbstractInsnNode> instructions,
                                                     org.objectweb.asm.tree.MethodInsnNode targetMethod)

Decides to call through the appropriate method to intercept the method with an INVOKEVIRTUAL Opcode, depending if the invokedynamic bytecode instruction is available (Java 7+).

makeMethodPublic

protected void makeMethodPublic(org.objectweb.asm.tree.MethodNode method)

Replaces protected and private method modifiers with public.

generateClassHandlerCall

protected abstract void generateClassHandlerCall(MutableClass mutableClass,
                                                 org.objectweb.asm.tree.MethodNode originalMethod,
                                                 java.lang.String originalMethodName,
                                                 org.robolectric.internal.bytecode.RobolectricGeneratorAdapter generator)
