Method Details

shouldProcess

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

Checks if this rule should even attempt to create a MethodRewriteRule.Rewrite for the current context. Returning true here does not mean a MethodRewriteRule.Rewrite 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

Returns:

true to continue processing the instruction

createVisitor

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

Specified by:

createVisitor in interface RewriteRule

rewrite

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