Constructor Detail

End

public End(String name)

Create a new end node with the given name.

Parameters:

Method Detail

getParent

public NodeBase getParent()

Returns the parent of this node.

Returns:

The parent of this node.

addParent

public void addParent(NodeBase parent)

Adds the provided node as a parent of this node.

Specified by:

addParent in class NodeBase

Parameters:

parent - The new parent of this node.

Throws:

IllegalStateException - if this node already has a parent.

addParentWithCondition

public void addParentWithCondition(Decision parent,
                                   Condition condition)

Adds the provided node as a conditional parent of this node.

Specified by:

addParentWithCondition in class NodeBase

Parameters:

parent - The new conditional parent of this node.

condition - The condition which must be true in addition the parent completing successfully for this node to be executed.

Throws:

IllegalStateException - if this node already has a parent.

addParentDefaultConditional

public void addParentDefaultConditional(Decision parent)

Adds the provided node as the default conditional parent of this node.

Specified by:

addParentDefaultConditional in class NodeBase

Parameters:

parent - The new conditional parent of this node.

Throws:

IllegalStateException - if this node already has a parent.

removeParent

public void removeParent(NodeBase parent)

Description copied from class: NodeBase

Removes a parent (whether or not conditional).

Specified by:

removeParent in class NodeBase

Parameters:

parent - The parent to remove.

clearParents

public void clearParents()

Description copied from class: NodeBase

Removes all parents (whether or not conditional) of this NodeBase object.

Specified by:

clearParents in class NodeBase

getChildren

public List<NodeBase> getChildren()

Description copied from class: NodeBase

Returns all the children (whether conditional or not) of this NodeBase object.

Specified by:

getChildren in class NodeBase

Returns:

All the children (whether conditional or not) of this NodeBase object.

addChild

protected void addChild(NodeBase child)

Description copied from class: NodeBase

Adds a child to this NodeBase object. This method should only be used in the implementation of the NodeBase.addParent(NodeBase) method of a subclass of NodeBase, so that whenever a node is assigned a new parent, the parent also knows about the child.

Specified by:

addChild in class NodeBase

Parameters:

child - The node to be added as the child of this NodeBase.

removeChild

protected void removeChild(NodeBase child)

Description copied from class: NodeBase

Removes the specified child from this NodeBase object. This method should only be used in the implementation of the NodeBase.removeParent(NodeBase) method of a subclass of NodeBase, so that whenever a child is removed from a node, the parent also knows about the child having been removed.

Specified by:

removeChild in class NodeBase

Parameters:

child - The node to be removed as the child of this NodeBase.
