Method Summary

Modifier and Type	Method and Description
void	postprocess(TransformerManager transformerManager, org.objectweb.asm.tree.ClassNode transformedClass, org.objectweb.asm.tree.MethodNode transformedMethod, java.util.List<org.objectweb.asm.tree.MethodInsnNode> transformerMethodCalls, org.objectweb.asm.tree.ClassNode transformer, org.objectweb.asm.tree.MethodNode transformerMethod) Postprocess the transformer and target method after the annotation handler injected calls to the target method. The transformerMethodCalls list only contains direct calls to the transformer method. Example usage: Add the parameter array back and modify the calls to the transformer method to use the parameter array.
org.objectweb.asm.tree.MethodNode	preprocess(TransformerManager transformerManager, org.objectweb.asm.tree.ClassNode transformedClass, org.objectweb.asm.tree.MethodNode transformedMethod, org.objectweb.asm.tree.ClassNode transformer, org.objectweb.asm.tree.MethodNode transformerMethod) Preprocess the target method before the annotation handler injects calls to the target method. This happens before the transformer method is verified by the annotation handler. Example usage: Merge all parameters into one array and add it to the end of the method.
org.objectweb.asm.tree.MethodNode	transform(TransformerManager transformerManager, org.objectweb.asm.tree.ClassNode transformedClass, org.objectweb.asm.tree.MethodNode transformedMethod, org.objectweb.asm.tree.ClassNode transformer, org.objectweb.asm.tree.MethodNode transformerMethod) Process the target method before the annotation handler injects calls to the target method. This happens before the transformer method is verified by the annotation handler but after IAnnotationCoprocessor.preprocess(TransformerManager, ClassNode, MethodNode, ClassNode, MethodNode). The calls to this method are in reverse order of the IAnnotationCoprocessor.preprocess(TransformerManager, ClassNode, MethodNode, ClassNode, MethodNode) calls. Example usage: Remove the previously added parameter array so the transformer method can be verified by the annotation handler.

Description copied from interface: IAnnotationCoprocessor

Preprocess the target method before the annotation handler injects calls to the target method.
This happens before the transformer method is verified by the annotation handler.

Example usage: Merge all parameters into one array and add it to the end of the method.

Specified by:

preprocess in interface IAnnotationCoprocessor

Parameters:

transformerManager - The transformer manager

transformedClass - The target class node

transformedMethod - The target method node

transformer - The transformer class node

transformerMethod - The transformer method node

Returns:

The preprocessed transformerMethod node

transform

public org.objectweb.asm.tree.MethodNode transform(TransformerManager transformerManager,
                                                   org.objectweb.asm.tree.ClassNode transformedClass,
                                                   org.objectweb.asm.tree.MethodNode transformedMethod,
                                                   org.objectweb.asm.tree.ClassNode transformer,
                                                   org.objectweb.asm.tree.MethodNode transformerMethod)

Description copied from interface: IAnnotationCoprocessor

Process the target method before the annotation handler injects calls to the target method.
This happens before the transformer method is verified by the annotation handler but after IAnnotationCoprocessor.preprocess(TransformerManager, ClassNode, MethodNode, ClassNode, MethodNode).
The calls to this method are in reverse order of the IAnnotationCoprocessor.preprocess(TransformerManager, ClassNode, MethodNode, ClassNode, MethodNode) calls.

Example usage: Remove the previously added parameter array so the transformer method can be verified by the annotation handler.

Specified by:

transform in interface IAnnotationCoprocessor

Parameters:

transformerManager - The transformer manager

transformedClass - The target class node

transformedMethod - The target method node

transformer - The transformer class node

transformerMethod - The transformer method node

Returns:

The preprocessed transformerMethod node
