Interface NESTSequentialWorkflowValidator

All Superinterfaces:

NESTGraphValidator

All Known Implementing Classes:

NESTSequentialWorkflowValidatorImpl

public interface NESTSequentialWorkflowValidator
extends NESTGraphValidator

To check if a NESTSequentialWorkflowObject is a valid nest sequential workflow, this class can be used. The validator provides several methods for performing fine-grained validations.

Method Summary

Modifier and Type	Method	Description
NESTAbstractWorkflowObject	getGraph()	This method returns the nest sequential object for which the validator was created.
boolean	hasValidDataNodes()	This method checks if all data nodes in the sequential workflow are valid.
boolean	hasValidEndNode()	This method verifies that the sequential workflow has only one end node and that it is a task node.
boolean	hasValidNodeTypes()	This method checks that the sequential workflow contains only task and data nodes and one workflow node.
boolean	hasValidSequence()	This method verifies that the sequential workflow is a valid sequence.
boolean	hasValidStartNode()	This method verifies that the sequential workflow has only one start node and that it is a task node.

Method Detail

isValidSequentialWorkflow

boolean isValidSequentialWorkflow()

This method checks whether the workflow is a valid nest sequential workflow. It checks if it is a valid graph, if it has a valid start and end node, if the node types and the sequence as well as the data nodes are correct. See methods NESTGraphValidator.isValidGraph(), hasValidStartNode(), hasValidEndNode(), hasValidNodeTypes(), hasValidSequence() and hasValidDataNodes().

Returns:

True, if sequential workflow is valid.

hasValidStartNode

boolean hasValidStartNode()

This method verifies that the sequential workflow has only one start node and that it is a task node.

Returns:

True, if start node is valid.

hasValidEndNode

boolean hasValidEndNode()

This method verifies that the sequential workflow has only one end node and that it is a task node.

Returns:

True, if end node is valid.

hasValidNodeTypes

boolean hasValidNodeTypes()

This method checks that the sequential workflow contains only task and data nodes and one workflow node.

Returns:

True, if all node types are valid.

hasValidSequence

boolean hasValidSequence()

This method verifies that the sequential workflow is a valid sequence. This means that each task node may have only one following task node and all task nodes must be between start and end nodes.

Returns:

True, if sequence is valid.

hasValidDataNodes

boolean hasValidDataNodes()

This method checks if all data nodes in the sequential workflow are valid. This is the case if all data nodes are connected to task nodes.

Returns:

True, if all data nodes are valid.

getGraph

NESTAbstractWorkflowObject getGraph()

This method returns the nest sequential object for which the validator was created.

Specified by:

getGraph in interface NESTGraphValidator

Returns:

The nest sequential workflow object for which the validator was created.
