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

invokeTarget

public Object invokeTarget()
                    throws Throwable

Invokes the target joinpoint for this invocation skipping any subsequent interceptors in the chain.

Specified by:

invokeTarget in interface Invocation

Overrides:

invokeTarget in class InvocationBase

Throws:

Throwable

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)

Returns 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 - chain of interceptors to be inserted on invocation

Returns:

an invocation wrapper

copy

public Invocation copy()

Copies complete state of Invocation object.

Returns:

a copy of this instance

getCalling

public Constructor<?> getCalling()

The constructor that is calling the method

Returns:

The constructor that is calling the method

getCalledMethod

public Method getCalledMethod()

Returns:

the method that is being called
