 Class<F> factoryClass,
 String classSuffix)

Method Details

getMixinCompiler

public MixinCompiler getMixinCompiler()

Description copied from interface: MixinFactory

Gets the associated MixinCompiler for this MixinFactory.

Specified by:

getMixinCompiler in interface MixinFactory<B,F>

Returns:

The MixinCompiler.

registerTrait

public MixinFactory.TraitKey registerTrait(Class<?> tClass)

Description copied from interface: MixinFactory

Registers a trait.

Specified by:

registerTrait in interface MixinFactory<B,F>

Parameters:

tClass - The trait class.

Returns:

a TraitKey for using this registered trait.

registerTrait

public MixinFactory.TraitKey registerTrait(org.objectweb.asm.tree.ClassNode cNode)

Description copied from interface: MixinFactory

Registers a binary trait. Used for traits which are generated at runtime.

Specified by:

registerTrait in interface MixinFactory<B,F>

Parameters:

cNode - The ClassNode for the trait.

Returns:

a TraitKey for using this registered trait.

construct

public F construct(com.google.common.collect.ImmutableSet<MixinFactory.TraitKey> traits)

Description copied from interface: MixinFactory

Returns a factory (MixinFactory) capable of constructing a new MixinFactory with the given set of traits applied.

The MixinFactory will cache constructed classes with the given set of traits, subsequent calls with the same traits will not cause a new class to be generated.

It should be noted that, ImmutableSet is explicitly used here, as their hashCode is statically computed, making it favourable for use as a key in a Map.

Specified by:

construct in interface MixinFactory<B,F>

Parameters:

traits - The traits to apply.

Returns:

The Factory.

getTraitsForClass

public com.google.common.collect.ImmutableSet<MixinFactory.TraitKey> getTraitsForClass(Class<?> clazz)

Description copied from interface: MixinFactory

Gets the traits that were used in compiling the given class. If the given class was not compiled by this factory, simply returns null.

Specified by:

getTraitsForClass in interface MixinFactory<B,F>

Parameters:

clazz - The Class to get the traits for.

Returns:

The classes traits, or null if it was not compiled by this factory.
