Method Detail

_execute

protected java.lang.Object _execute(Action action,
                                    StateMachineContext context)
                             throws com.evelopers.common.exception.SystemException

This executes given action.

Controlled object handler of the action is used only to find controlled object's name. To get real controlled object instance this method uses ControlledObjectsMap passed to constructor.

Parameters:

action - action to execute

context - action context

Returns:

return-value of the action

Throws:

com.evelopers.common.exception.SystemException - if action couldn't be executed or have thrown exception

execute

public void execute(Action action,
                    StateMachineContext context)
             throws EventProcessorException

Executes action against given context, ignoring return type.

Parameters:

action - action to execute

context - state machine runtime context

Throws:

EventProcessorException - if error while executing occurs

executeNum

public int executeNum(Action action,
                      StateMachineContext context)
               throws InterpreterException

Executes action against given context, treating return type as int.

Parameters:

action - action to execute

context - state machine runtime context

Returns:

usually 0 as false and 1 as true. Returned values of input actions only will be taken into account by runtime interpretter.

Throws:

InterpreterException - if error while executing occurs or return type is not int.

executeBool

public boolean executeBool(Action action,
                           StateMachineContext context)
                    throws InterpreterException

Executes action against given context, treating return type as boolean.

Parameters:

action - action to execute

context - state machine runtime context

Returns:

boolean
