Constructor Detail

Appender

protected Appender(Implementation.Target implementationTarget,
                   MethodCall.TerminationHandler terminationHandler)

Creates a new appender.

Parameters:

implementationTarget - The implementation target.

terminationHandler - The termination handler to use.

Method Detail

apply

public ByteCodeAppender.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
                                   Implementation.Context implementationContext,
                                   MethodDescription instrumentedMethod)

Applies this byte code appender to a type creation process.

Specified by:

apply in interface ByteCodeAppender

Parameters:

methodVisitor - The method visitor to which the byte code appender writes its code to.

implementationContext - The implementation context of the current type creation process.

instrumentedMethod - The method that is the target of the instrumentation.

Returns:

The required size for the applied byte code to run.

toInvokedMethod

protected MethodDescription toInvokedMethod(MethodDescription instrumentedMethod,
                                            MethodCall.TargetHandler.Resolved targetHandler)

Resolves this appender to the method being invoked.

Parameters:

instrumentedMethod - The instrumented method.

targetHandler - The resolved target handler to base the stack manipulation upon.

Returns:

The invoked method.

toStackManipulation

protected StackManipulation toStackManipulation(MethodDescription instrumentedMethod,
                                                MethodDescription invokedMethod,
                                                MethodCall.TargetHandler.Resolved targetHandler)

Resolves this appender to a stack manipulation.

Parameters:

instrumentedMethod - The instrumented method.

invokedMethod - The invoked method.

targetHandler - The resolved target handler to base the stack manipulation upon.

Returns:

A stack manipulation that represents this method call.
