CatchContext

public CatchContext(Context c,
 StateMachine sm,
 ScriptParser parser)

Method Details

transmitErrorInfo

protected void transmitErrorInfo(Justification details)

Transmits error information to the catch context. To add support for a new failure state, add an new case in the switch statement, changing the type cast to the appropriate type for the error status. See setupArguments().

Parameters:

details - details about the error

setupArguments

protected void setupArguments(List<? extends Object> inputArgs,
 List<? extends Object> returnArgs)

Sets up the arguments for the catch context. To add support for a new failure state, add a new case in the switch statement, creating an ActionBinding for the appropriate type (error message type). See transmitErrorInfo().

Specified by:

setupArguments in class ArgumentBasedContext

Parameters:

inputArgs -

returnArgs -

setupNextStep

protected void setupNextStep()

Description copied from class: Context

If Context can have next steps (i.e., children), implement this method to add the next child context that should be executed.

Overrides:

setupNextStep in class Context

getStatusToCatch

public ActionStatus getStatusToCatch()

Get ActionStatus that this CatchContext is capable of catching.

Returns:

copy

public CatchContext copy(Context newParent)

Description copied from class: Context

deep copy of the context, its status, and its children

Specified by:

copy in class Context

Parameters:

newParent - parent to attach the copied context too

Returns:

the copied context
