Constructor Details

CallbackInjector

public CallbackInjector(InjectionInfo info,
 boolean cancellable,
 LocalCapture localCapture,
 String identifier)

Make a new CallbackInjector with the supplied args

Parameters:

info - information about this injector

cancellable - True if injections performed by this injector should be cancellable

localCapture - Local variable capture behaviour

Method Details

sanityCheck

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

Overrides:

sanityCheck in class Injector

addTargetNode

inject

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

Specified by:

inject in class Injector

instanceCallbackInfo

protected void instanceCallbackInfo(org.spongepowered.asm.mixin.injection.callback.CallbackInjector.Callback callback,
 String id,
 String desc,
 boolean store)

Parameters:

callback - callback handle

id - callback id

desc - constructor descriptor

store - true if storing in a local, false if this is happening at an invoke

injectCancellationCode

protected void injectCancellationCode(org.spongepowered.asm.mixin.injection.callback.CallbackInjector.Callback callback)

if (e.isCancelled()) return e.getReturnValue();

Parameters:

callback - callback handle

Inject the appropriate return code for the method type

Parameters:

callback - callback handle

isStatic

protected boolean isStatic()

Explicit to avoid creation of synthetic accessor

Returns:

true if the target method is static
