Method Details

shouldProcess

boolean shouldProcess(ClassProcessingContext context,
 int opcode,
 String owner,
 String name,
 String descriptor,
 boolean isInterface,
 boolean isInvokeDynamic)

Checks if this rule should even attempt to create a MethodRewrite for the current context. Returning true here does not mean a MethodRewrite will be created, but it's an early exit for rules that know they won't be able to rewrite the method.

Parameters:

context - the current context

opcode - the method opcode

owner - the method owner (with slashes)

name - the method name

descriptor - the method descriptor

isInterface - if the owning class is an interface

isInvokeDynamic - if the method call is from an invokedynamic instruction

Returns:

true to continue processing the instruction

rewrite

@Nullable MethodRewrite<?> rewrite(ClassProcessingContext context,
 boolean isInvokeDynamic,
 int opcode,
 ClassDesc owner,
 String name,
 MethodTypeDesc descriptor,
 boolean isInterface)

Creates a MethodRewrite which will be applied to the processed bytecode.

Parameters:

context - the current context

isInvokeDynamic - if this is in an invokedynamic instruction

opcode - the opcode of the invoke instruction or the invokedynamic handle tag

owner - the owner of the invoke method or the owner of the invokedynamic handle

name - the name of the invoke method or the name of the invokedynamic handle

descriptor - the descriptor of the invoke method or the descriptor of the invokedynamic handle

isInterface - if the method is an interface method

Returns:

the rewrite or null if no rewrite should be applied

createVisitor

default ClassVisitor createVisitor(int api,
 ClassVisitor parent,
 ClassProcessingContext context)
