Constructor Detail

IlrTaskInstanceStatement

public IlrTaskInstanceStatement(String label,
                                IlrTaskFactory task)

Builds a task invocation node for a ruleflow. It is useful to set a label if the node is the target of a goto statement.

Parameters:

label - The label used to target the node in a goto statement.

task - The task to which the node refers.

IlrTaskInstanceStatement

public IlrTaskInstanceStatement(String label,
                                IlrTaskFactory task,
                                IlrFlowNodeStatement previousNode)

Builds a task invocation node for a ruleflow and connects the created node to the passed node. This constructor must not be called to connect the new node to an IlrTaskIfNodeStatement nor to an IlrTaskSwitchNodeStatement; instead use IlrTaskIfNodeStatement.setTrueNode, IlrTaskIfNodeStatement.setFalseNode, IlrTaskSwitchNodeStatement.setCaseNode, or IlrTaskSwitchNodeStatement.setDefaultNode. It is useful to set a label if the node is the target of a goto statement.

Parameters:

label - The label used to target the node in a goto statement.

task - The task to which the node refers.

previousNode - The node that is before the new node in the ruleflow. The two nodes are connected by calling the method IlrFlowNodeStatement.setNextNode.

Method Detail

getTask

public IlrTaskFactory getTask()

Returns the task invoked in the node.

Returns:

The task referred to by the node.

setNextNode

public void setNextNode(IlrFlowNodeStatement node)

Connects the passed node to this. The connected node is executed after this during the flow execution.

Specified by:

setNextNode in class IlrFlowNodeStatement

Parameters:

node - The node connected after this.
