protected java.lang.String	getTargetNodeKey(Target target, InjectionNodes.InjectionNode node) Generate a key which uniquely identifies the combination of return type, frame type and target injection node so that injectors targetting the same instruction still get unique contexts.

Method Detail

findTargetNodes

protected boolean findTargetNodes(org.objectweb.asm.tree.MethodNode into,
                                  InjectionPoint injectionPoint,
                                  InjectorTarget injectorTarget,
                                  java.util.Collection<org.objectweb.asm.tree.AbstractInsnNode> nodes)

Overrides:

findTargetNodes in class Injector

sanityCheck

protected void sanityCheck(Target target,
                           java.util.List<InjectionPoint> injectionPoints)

Overrides:

sanityCheck in class Injector

getTargetNodeKey

protected java.lang.String getTargetNodeKey(Target target,
                                            InjectionNodes.InjectionNode node)

Generate a key which uniquely identifies the combination of return type, frame type and target injection node so that injectors targetting the same instruction still get unique contexts.

Parameters:

target - Target method

node - Target node

Returns:

Key for storing/retrieving the injector context decoration

preInject

protected void preInject(Target target,
                         InjectionNodes.InjectionNode node)

Overrides:

preInject in class Injector

inject

protected void inject(Target target,
                      InjectionNodes.InjectionNode node)

Do the injection

Specified by:

inject in class Injector
