java.lang.Object

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

All Implemented Interfaces:

IClassGenerator

public final class ArgsClassGenerator
extends java.lang.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.

Method Detail

getClassName

public java.lang.String getClassName(java.lang.String desc)

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

Returns:

name of the Args subclass to use

getClassRef

public java.lang.String getClassRef(java.lang.String desc)

Get (or generate) the class name for the specified descriptor in internal format (reference). 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, with the return type changed to void (V)

Returns:

reference of the Args subclass to use

generate

public byte[] generate(java.lang.String name)

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

Returns:

Class bytecode or null

getBytes

public byte[] getBytes(java.lang.String name)

Fetch or generate class bytes for the specified class name. Returns null if this generator does not have bytes for the specified class.

Parameters:

name - Class name

Returns:

class bytes or null
