Class ArgsClassGenerator

java.lang.Object

org.spongepowered.asm.mixin.injection.invoke.arg.ArgsClassGenerator

All Implemented Interfaces:

IClassGenerator

public final class ArgsClassGenerator
extends Object
implements IClassGenerator

Class generator which creates subclasses of Args to be used by the ModifyArgs injector. The subclasses contain getter and setter logic to provide access to a particular configuration of arguments and classes are only generated for each unique argument combination.

Parameters:

Method Details

getName

public String getName()

Description copied from interface: IClassGenerator

Get the name of this generator for logging and auditing purposes

Specified by:

getName in interface IClassGenerator

getArgsClass

public ISyntheticClassInfo getArgsClass(String desc,
 IMixinInfo mixin)

Get (or generate) the class name for the specified descriptor. The class will not be generated until it is used. Calling this method simply allocates a name for the specified descriptor.

Parameters:

desc - Descriptor of the target method, the return type is ignored for the purposes of generating Args subclasses

mixin - Mixin which requires the class. Only the first mixin to request a class will be registered against it but this is for debugging only anyway

Returns:

name of the Args subclass to use

generate

public boolean generate(String name,
 org.objectweb.asm.tree.ClassNode classNode)

Description copied from interface: IClassGenerator

Generate (if possible) the specified class name. The generator should return null if it cannot generate the specified class, in order that the next generator in the chain can process the request. The first generator to return a value will halt further processing of the request.

Specified by:

generate in interface IClassGenerator

Parameters:

name - Class name to generate

classNode - Empty ClassNode to populate

Returns:

True if the class was generated
