Constructor Detail

UnpickV2Remapper

public UnpickV2Remapper(java.util.Map<java.lang.String,java.lang.String> classMappings,
                        java.util.Map<MethodKey,java.lang.String> methodMappings,
                        UnpickV2Reader.Visitor delegate)

Creates a new UnpickV2Remapper.

Parameters:

classMappings - a mapping of old class names to new class names.

methodMappings - a mapping of old method names, owner classes, and descriptors; to new method names.

delegate - the visitor that should visit the remapped target method definitions. All other visitor methods only delegate to the delegate visitor.

Method Detail

visitTargetMethodDefinition

public UnpickV2Reader.TargetMethodDefinitionVisitor visitTargetMethodDefinition(java.lang.String owner,
                                                                                java.lang.String name,
