Method Details

reset

public void reset()

Description copied from interface: NESTGraphValidator

The method resets all values stored in the validator. This method is to be used when changes have been made to the graph object after validation by the validator.

Specified by:

reset in interface NESTGraphValidator

Overrides:

reset in class NESTGraphValidatorImpl

isValidSequentialWorkflow

public boolean isValidSequentialWorkflow()

Description copied from interface: NESTSequentialWorkflowValidator

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(), NESTSequentialWorkflowValidator.hasValidStartNode(), NESTSequentialWorkflowValidator.hasValidEndNode(), NESTSequentialWorkflowValidator.hasValidNodeTypes(), NESTSequentialWorkflowValidator.hasValidSequence() and NESTSequentialWorkflowValidator.hasValidDataNodes().

Specified by:

isValidSequentialWorkflow in interface NESTSequentialWorkflowValidator

Returns:

True, if sequential workflow is valid.

hasValidStartNode

public boolean hasValidStartNode()

Description copied from interface: NESTSequentialWorkflowValidator

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

Specified by:

hasValidStartNode in interface NESTSequentialWorkflowValidator

Returns:

True, if start node is valid.

hasValidEndNode

public boolean hasValidEndNode()

Description copied from interface: NESTSequentialWorkflowValidator

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

Specified by:

hasValidEndNode in interface NESTSequentialWorkflowValidator

Returns:

True, if end node is valid.

hasValidNodeTypes

public boolean hasValidNodeTypes()

Description copied from interface: NESTSequentialWorkflowValidator

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

Specified by:

hasValidNodeTypes in interface NESTSequentialWorkflowValidator

Returns:

True, if all node types are valid.

hasValidSequence

public boolean hasValidSequence()

Description copied from interface: NESTSequentialWorkflowValidator

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.

Specified by:

hasValidSequence in interface NESTSequentialWorkflowValidator

Returns:

True, if sequence is valid.

hasValidDataNodes

public boolean hasValidDataNodes()

Description copied from interface: NESTSequentialWorkflowValidator

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.

Specified by:

hasValidDataNodes in interface NESTSequentialWorkflowValidator

Returns:

True, if all data nodes are valid.

getGraph

public NESTAbstractWorkflowObject getGraph()

Description copied from interface: NESTGraphValidator

This method returns the graph object for which the validator was created.

Specified by:

getGraph in interface NESTGraphValidator

Specified by:

getGraph in interface NESTSequentialWorkflowValidator

Overrides:

getGraph in class NESTGraphValidatorImpl

Returns:

The graph object for which the validator was created.
