Constructor Detail

MockActionInvocation

public MockActionInvocation()
Method Detail

getAction

public java.lang.Object getAction()
Description copied from interface: ActionInvocation
Get the Action associated with this ActionInvocation.

Specified by:
getAction in interface ActionInvocation
Returns:
the Action

setAction

public void setAction(java.lang.Object action)

getInvocationContext

public ActionContext getInvocationContext()
Description copied from interface: ActionInvocation
Gets the ActionContext associated with this ActionInvocation. The ActionProxy is responsible for setting this ActionContext onto the ThreadLocal before invoking the ActionInvocation and resetting the old ActionContext afterwards.

Specified by:
getInvocationContext in interface ActionInvocation
Returns:
the ActionContext.

setInvocationContext

public void setInvocationContext(ActionContext invocationContext)

getProxy

public ActionProxy getProxy()
Description copied from interface: ActionInvocation
Get the ActionProxy holding this ActionInvocation.

Specified by:
getProxy in interface ActionInvocation
Returns:
the ActionProxy.

setProxy

public void setProxy(ActionProxy proxy)

getResult

public Result getResult()
Description copied from interface: ActionInvocation
If the ActionInvocation has been executed before and the Result is an instance of ActionChainResult, this method will walk down the chain of ActionChainResults until it finds a non-chain result, which will be returned. If the ActionInvocation's result has not been executed before, the Result instance will be created and populated with the result params.

Specified by:
getResult in interface ActionInvocation
Returns:
the result.

setResult

public void setResult(Result result)

getResultCode

public java.lang.String getResultCode()
Description copied from interface: ActionInvocation
Gets the result code returned from this ActionInvocation.

Specified by:
getResultCode in interface ActionInvocation
Returns:
the result code

setResultCode

public void setResultCode(java.lang.String resultCode)
Description copied from interface: ActionInvocation
Sets the result code, possibly overriding the one returned by the action.

The "intended" purpose of this method is to allow PreResultListeners to override the result code returned by the Action.

If this method is used before the Action executes, the Action's returned result code will override what was set. However the Action could (if specifically coded to do so) inspect the ActionInvocation to see that someone "upstream" (e.g. an Interceptor) had suggested a value as the result, and it could therefore return the same value itself.

If this method is called between the Action execution and the Result execution, then the value set here will override the result code the action had returned. Creating an Interceptor that implements PreResultListener will give you this oportunity.

If this method is called after the Result has been executed, it will have the effect of raising an IllegalStateException.

Specified by:
setResultCode in interface ActionInvocation
Parameters:
resultCode - the result code.

ActionInvocation.isExecuted()

getStack

public ValueStack getStack()
Description copied from interface: ActionInvocation
Gets the ValueStack associated with this ActionInvocation.

Specified by:
getStack in interface ActionInvocation
Returns:
the ValueStack

setStack

public void setStack(ValueStack stack)

isExecuted

public boolean isExecuted()
Description copied from interface: ActionInvocation
Gets whether this ActionInvocation has executed before. This will be set after the Action and the Result have executed.

Specified by:
isExecuted in interface ActionInvocation
Returns:
true if this ActionInvocation has executed before.

addPreResultListener

public void addPreResultListener(PreResultListener listener)
Description copied from interface: ActionInvocation
Register a PreResultListener to be notified after the Action is executed and before the Result is executed.

The ActionInvocation implementation must guarantee that listeners will be called in the order in which they are registered.

Listener registration and execution does not need to be thread-safe.

Specified by:
addPreResultListener in interface ActionInvocation
Parameters:
listener - the listener to add.

invoke

public java.lang.String invoke()
                        throws java.lang.Exception
Description copied from interface: ActionInvocation
Invokes the next step in processing this ActionInvocation.

If there are more Interceptors, this will call the next one. If Interceptors choose not to short-circuit ActionInvocation processing and return their own return code, they will call invoke() to allow the next Interceptor to execute. If there are no more Interceptors to be applied, the Action is executed. If the ActionProxy.getExecuteResult() method returns true, the Result is also executed.

Specified by:
invoke in interface ActionInvocation
Returns:
the return code.
Throws:
java.lang.Exception - can be thrown.

invokeActionOnly

public java.lang.String invokeActionOnly()
                                  throws java.lang.Exception
Description copied from interface: ActionInvocation
Invokes only the Action (not Interceptors or Results).

This is useful in rare situations where advanced usage with the interceptor/action/result workflow is being manipulated for certain functionality.

Specified by:
invokeActionOnly in interface ActionInvocation
Returns:
the return code.
Throws:
java.lang.Exception - can be thrown.

setActionEventListener

public void setActionEventListener(ActionEventListener listener)
Description copied from interface: ActionInvocation
Sets the action event listener to respond to key action events.

Specified by:
setActionEventListener in interface ActionInvocation
Parameters:
listener - the listener.

getActionEventListener

public ActionEventListener getActionEventListener()

init

public void init(ActionProxy proxy)
Specified by:
init in interface ActionInvocation
