Class InjectionNodes.InjectionNode

java.lang.Object

org.spongepowered.asm.mixin.injection.struct.InjectionNodes.InjectionNode

All Implemented Interfaces:

java.lang.Comparable<InjectionNodes.InjectionNode>

Enclosing class:

InjectionNodes

public static class InjectionNodes.InjectionNode
extends java.lang.Object
implements java.lang.Comparable<InjectionNodes.InjectionNode>

A node targetted by one or more injectors. Using this wrapper allows injectors to be aware of when their target node is removed or replace by another injector. It also allows injectors to decorate certain nodes with custom metadata to allow arbitration between injectors to take place.
