public SimpleInvocationContext(Object target,
                               Method method,
                               Object[] parameters)

Method Detail

getTarget

public Object getTarget()

Specified by:

getTarget in interface javax.interceptor.InvocationContext

getMethod

public Method getMethod()

Specified by:

getMethod in interface javax.interceptor.InvocationContext

getParameters

public Object[] getParameters()

Specified by:

getParameters in interface javax.interceptor.InvocationContext

setParameters

public void setParameters(Object[] parameters)

Specified by:

setParameters in interface javax.interceptor.InvocationContext

getContextData

public Map<String,Object> getContextData()

Specified by:

getContextData in interface javax.interceptor.InvocationContext

getTimer

public Object getTimer()

Specified by:

getTimer in interface javax.interceptor.InvocationContext

proceed

public Object proceed()
               throws Exception

Throw an exception indicating that the end of the interceptor chain was reached without an invocation being performed. This method should be overridden to provide a specific implementation. Though this method always throws CannotProceedException, it is declared to throw Exception so that subclasses can override this method in a spec-compliant way.

Specified by:

proceed in interface javax.interceptor.InvocationContext

Returns:

nothing

Throws:

Exception - always (in particular, CannotProceedException)
