IDynamicRemapper

All Known Implementing Classes:

CModifyConstantAnnotationHandler, ConstantTarget, FieldTarget, HeadTarget, InvokeTarget, NewTarget, OpcodeTarget, ReturnTarget, TailTarget, ThrowTarget

extends IDynamicRemapper

The interface which is used to define a target for an injection.

Method Summary

Modifier and Type	Method and Description
default RemapType	dynamicRemap(AMapper mapper, java.lang.Class<?> annotation, java.util.Map<java.lang.String,java.lang.Object> values, java.lang.reflect.Method remappedMethod, TransformerManager transformerManager, org.objectweb.asm.tree.ClassNode target, org.objectweb.asm.tree.ClassNode transformer) Remap the annotation fields dynamically. A new type can be returned to let the default remapper handle the remapping. If the return value is null or RemapType.DYNAMIC the default remapper will be skipped.
default CTarget.Shift	getShift(CTarget target) Get the shift for this target. By default, it is defined in the CTarget annotation.
default java.util.List<org.objectweb.asm.tree.AbstractInsnNode>	getSlice(java.util.Map<java.lang.String,IInjectionTarget> injectionTargets, org.objectweb.asm.tree.MethodNode method, CSlice slice) Get all instructions in the given slice.
java.util.List<org.objectweb.asm.tree.AbstractInsnNode>	getTargets(java.util.Map<java.lang.String,IInjectionTarget> injectionTargets, org.objectweb.asm.tree.MethodNode method, CTarget target, CSlice slice) Get all matching target instructions.

Description copied from interface: IDynamicRemapper

Remap the annotation fields dynamically.
A new type can be returned to let the default remapper handle the remapping.
If the return value is null or RemapType.DYNAMIC the default remapper will be skipped.

Specified by:

dynamicRemap in interface IDynamicRemapper

Parameters:

mapper - The mapper instance

annotation - The annotation class

values - The raw values of the annotation

remappedMethod - The annotation method that is being remapped

transformerManager - The transformer manager

target - The transformer target class

transformer - The transformer class

Returns:

The new remap type
