Class InterpretationEventProcessor

java.lang.Object
  com.evelopers.unimod.runtime.AbstractEventProcessor
      com.evelopers.unimod.runtime.interpretation.InterpretationEventProcessor

All Implemented Interfaces:

EventProcessor

class InterpretationEventProcessor

extends AbstractEventProcessor

Abstract low-level event processor implementation.

Concrete implementation responsible for realization of state machine runtime sematic such as selection of transition for event, processing input and output actions and so on.

Pattern used: Template Method

Constructor Summary

InterpretationEventProcessor(Model model)
Creates processor

Method Summary

ModelStructure	getModelStructure() Returns the structure of the model.
protected StateMachineConfig	process(Event event, StateMachineContext context, StateMachinePath path, StateMachineConfig config) Processes given event using state machine instance defined by the given config.
protected StateMachineConfig	transiteToStableState(StateMachineContext context, StateMachinePath path, StateMachineConfig config) Transites from initial state config to stable state.

public InterpretationEventProcessor(Model model)

Creates processor

Parameters:

model - automata model

Method Detail

getModelStructure

public ModelStructure getModelStructure()

Description copied from class: AbstractEventProcessor

Returns the structure of the model.

Specified by:

getModelStructure in interface EventProcessor

Specified by:

getModelStructure in class AbstractEventProcessor

Returns:

the structure of the model

transiteToStableState

protected StateMachineConfig transiteToStableState(StateMachineContext context,
                                                   StateMachinePath path,
                                                   StateMachineConfig config)
                                            throws com.evelopers.common.exception.SystemException

Description copied from class: AbstractEventProcessor

Transites from initial state config to stable state. This method should:

1. Get transition from current initial state
2. Transite using this transition
3. If target state is composite then
   1. AbstractEventProcessor.fireCompositeTargetState(com.evelopers.unimod.runtime.context.StateMachineContext, com.evelopers.unimod.runtime.StateMachinePath, java.lang.String)
   2. Get initial state from the composite state
   3. AbstractEventProcessor.fireComeToState(com.evelopers.unimod.runtime.context.StateMachineContext, com.evelopers.unimod.runtime.StateMachinePath, java.lang.String) for new initial state
   4. Repeat AbstractEventProcessor.transiteToStableState(com.evelopers.unimod.runtime.context.StateMachineContext, com.evelopers.unimod.runtime.StateMachinePath, com.evelopers.unimod.runtime.StateMachineConfig) with new initial state

Specified by:

transiteToStableState in class AbstractEventProcessor

Parameters:

context - state machine context of the event

path - path that defines the state machine instance

config - initial state to transite from

Returns:

stable state reached from the given initial

Throws:

com.evelopers.common.exception.SystemException

process

protected StateMachineConfig process(Event event,
                                     StateMachineContext context,
                                     StateMachinePath path,
                                     StateMachineConfig config)
                              throws com.evelopers.common.exception.SystemException

Description copied from class: AbstractEventProcessor

Processes given event using state machine instance defined by the given config.

Implementation of this method depends on approach. For instance it may be an interpretator of the in-memory state machine model or a precompiled switch-operator.

Implementations of this method should fire event processing events during execution.

Specified by:

process in class AbstractEventProcessor

Parameters:

event - triggered event to process

context - state machine context of the event

path - path to state machine instance

config - state machine config that defines the state machine instance

Returns:

state machine config after event processing

Throws:

com.evelopers.common.exception.SystemException - if some input or output action throws an exception. This exception will be handled by added ExceptionHandlers
