public class IlrTaskGotoNodeStatement
extends IlrControlNodeStatement

This class represents the class of a jump instruction in a ruleflow. It groups three kinds of jumps that can be found in a ruleflow:

• goto instruction
• break instruction
• continue instruction.

Warning: Serialized objects of this class will not be compatible with future releases. The current serialization support is appropriate for short-term storage or RMI between applications running the same version of IBM Decision Server.

Field Summary

static int	Break This value is used to give a break behavior to the jump node, used in a while block.
static int	Continue This value is used to give a continue behavior to the jump node, used in a while block.
static int	Goto This value is used to give a goto behavior to the jump node.

Constructor Summary

IlrTaskGotoNodeStatement(int kind)
Builds a jump instruction node for a ruleflow.

IlrTaskGotoNodeStatement(int kind, IlrFlowNodeStatement previousNode)
Builds a jump instruction node for a ruleflow and connects the created node to the passed node.

Method Summary

String	getGotoLabel() Returns the label of the node on which the goto node points.
int	getKind() Returns the jump node kind.
void	setGotoLabel(String label) Sets the label of the node to which the ruleflow execution is directed after the execution of the goto node.

Constructor Detail

IlrTaskGotoNodeStatement

public IlrTaskGotoNodeStatement(int kind)

Builds a jump instruction node for a ruleflow.

We specify the kind of jump by passing one of the following values:

• IlrTaskGotoNodeStatement.Goto
• IlrTaskGotoNodeStatement.Break
• IlrTaskGotoNodeStatement.Continue

If a wrong value is passed, an IllegalArgumentException is thrown.

Parameters:

kind - The kind of jump node.

IlrTaskGotoNodeStatement

public IlrTaskGotoNodeStatement(int kind,
                                IlrFlowNodeStatement previousNode)

Builds a jump instruction 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.

We specify the kind of jump by passing one of the following values:

• IlrTaskGotoNodeStatement.Goto
• IlrTaskGotoNodeStatement.Break
• IlrTaskGotoNodeStatement.Continue

If a wrong value is passed, an IllegalArgumentException is thrown.

Parameters:

kind - The kind of jump node.

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

setGotoLabel

public void setGotoLabel(String label)

Sets the label of the node to which the ruleflow execution is directed after the execution of the goto node. This method must be used only for a goto node whose kind is Goto, or else an IllegalArgumentException is thrown.

Parameters:

label - The label of the node on which the goto node points.

getGotoLabel

public String getGotoLabel()

Returns the label of the node on which the goto node points. This is the node that will be executed after the goto node.

Returns:

The label of the node pointed to by the this.

getKind

public int getKind()

Returns the jump node kind. The possible values are:

• IlrTaskGotoNodeStatement.Goto
• IlrTaskGotoNodeStatement.Break
• IlrTaskGotoNodeStatement.Continue.

Returns:

The kind of the node.
