Constructor Detail

Appender

protected Appender(StackManipulation preparingStackAssignment,
                   Instrumentation.Target instrumentationTarget,
                   Iterable<? extends MethodDescription> targetMethods,
                   MethodDelegationBinder.Processor processor)

Creates a new appender.

Parameters:

preparingStackAssignment - The stack manipulation that is responsible for loading a potential target instance onto the stack on which the target method is invoked.

instrumentationTarget - The instrumentation target of this instrumentation.

targetMethods - The method candidates to consider for delegating the invocation to.

processor - The method delegation binder processor which is responsible for implementing the method delegation.

Method Detail

appendsCode

public boolean appendsCode()

Description copied from interface: ByteCodeAppender

Determines if this byte code appender offers an (possibly empty) implementation of a method.

Specified by:

appendsCode in interface ByteCodeAppender

Returns:

true if this byte code appender requires this method to be implemented or false if this appender describes an abstract method.

apply

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

Description copied from interface: ByteCodeAppender

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.

instrumentationContext - The instrumentation 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.

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:
