org.spongepowered.asm.transformers.TreeTransformer

org.spongepowered.asm.mixin.transformer.MixinTransformer

All Implemented Interfaces:

ILegacyClassTransformer, ITransformer

public class MixinTransformer
extends TreeTransformer

Transformer which manages the mixin configuration and application process

Method Summary

Modifier and Type	Method and Description
void	audit(MixinEnvironment environment) Force-load all classes targetted by mixins but not yet applied
java.lang.String	getName() Get the identifier for this transformer, usually the class name but for wrapped transformers this is the class name of the wrapped transformer
boolean	isDelegationExcluded() Get whether this transformer is excluded from delegation.
java.util.List<java.lang.String>	reload(java.lang.String mixinClass, byte[] bytes) Update a mixin class with new bytecode.
byte[]	transformClassBytes(java.lang.String name, java.lang.String transformedName, byte[] basicClass) Transform a class in byte array form.

Method Detail

audit

public void audit(MixinEnvironment environment)

Force-load all classes targetted by mixins but not yet applied

Parameters:

environment - current environment

getName

public java.lang.String getName()

Description copied from interface: ILegacyClassTransformer

Get the identifier for this transformer, usually the class name but for wrapped transformers this is the class name of the wrapped transformer

Returns:

transformer's identifying name

isDelegationExcluded

public boolean isDelegationExcluded()

Description copied from interface: ILegacyClassTransformer

Get whether this transformer is excluded from delegation. Some transformers (such as the mixin transformer itself) should not be included in the delegation list because they are re-entrant or do not need to run on incoming bytecode.

Returns:

true if this transformer should be excluded from the transformer delegation list

transformClassBytes

public byte[] transformClassBytes(java.lang.String name,
                                  java.lang.String transformedName,
                                  byte[] basicClass)

Description copied from interface: ILegacyClassTransformer

Transform a class in byte array form.

Parameters:

name - Class original name

transformedName - Class name after being processed by the class name transformer

basicClass - class byte array

Returns:

transformed bytes

reload

public java.util.List<java.lang.String> reload(java.lang.String mixinClass,
                                               byte[] bytes)

Update a mixin class with new bytecode.

Parameters:

mixinClass - Name of the mixin

bytes - New bytecode

Returns:

List of classes that need to be updated
