Method Detail

invokeNext

public Object invokeNext()
                  throws Throwable
Invoke on the next interceptor in the chain. If this is already the end of the chain, reflection will call the constructor, field, or method you are invoking on.

Specified by:
invokeNext in interface Invocation
Overrides:
invokeNext in class InvocationBase
Throws:
Throwable

resolveAnnotation

public Object resolveAnnotation(Class annotation)
This method resolves an annotation based on the context of the invocation.

Specified by:
resolveAnnotation in interface Invocation
Overrides:
resolveAnnotation in class InvocationBase
Returns:

getMetaData

public Object getMetaData(Object group,
                          Object attr)
This method resolves metadata based on the context of the invocation. It iterates through its list of MetaDataResolvers to find out the value of the metadata desired. This list usually is ThreadMetaData, InstanceAdvisor.getMetaData ClassAdvisor.getMethodMetaData (or field, or constructor) ClassAdvisor.getDefaultMetaData

Specified by:
getMetaData in interface Invocation
Overrides:
getMetaData in class InvocationBase

getWrapper

public Invocation getWrapper(Interceptor[] newchain)
Get a wrapper invocation object that can insert a new chain of interceptors at runtime to the invocation flow. CFlow makes use of this. When the wrapper object finishes its invocation chain it delegates back to the wrapped invocation.

Parameters:
newchain -
Returns:

copy

public Invocation copy()
Copies complete state of Invocation object.

Returns:

getArguments

public Object[] getArguments()

setArguments

public void setArguments(Object[] arguments)

getConstructor

public Constructor getConstructor()

setConstructor

public void setConstructor(Constructor constructor)
