Field Detail

_level

protected int _level

level in the hierarchy.

Constructor Detail

DefaultTimeBarNode

public DefaultTimeBarNode(TimeBarRowHeader header)

Constructor.

Parameters:

header - row header.

DefaultTimeBarNode

public DefaultTimeBarNode()

Default row header. Constructs a default row header with an empty string.

Method Detail

getChildren

public java.util.List<TimeBarNode> getChildren()

Retrieve all children of the node.

Specified by:

getChildren in interface TimeBarNode

Returns:

chrildren of the node

addNode

public void addNode(TimeBarNode node)

Add a node as a child.

Specified by:

addNode in interface TimeBarNode

Parameters:

node - child to be added.

remNode

public void remNode(TimeBarNode node)

Remove a child node.

Specified by:

remNode in interface TimeBarNode

Parameters:

node - node to remove

getLevel

public int getLevel()

Retrieve the level in the tree.

Specified by:

getLevel in interface TimeBarNode

Returns:

level in the tree.

setLevel

public void setLevel(int level)

Tell the node it's level. Storing the level of the node directly with the node is not an optimal solution. However it is fast and straight forward.

Specified by:

setLevel in interface TimeBarNode

Parameters:

level - level of the node

addTimeBarNodeListener

public void addTimeBarNodeListener(TimeBarNodeListener tbnl)

Add a listener to listen for node changes.

Specified by:

addTimeBarNodeListener in interface TimeBarNode

Parameters:

tbnl - listener to add

removeTimeBarNodeListener

public void removeTimeBarNodeListener(TimeBarNodeListener tbnl)

Remove a listener registered for node changes.

Specified by:

removeTimeBarNodeListener in interface TimeBarNode

Parameters:

tbnl - listener to remove

fireNodeAdded

protected void fireNodeAdded(TimeBarNode newNode)

Inform listeners about a new child.

Parameters:

newNode - the added node

fireNodeRemoved

protected void fireNodeRemoved(TimeBarNode removedNode)

Inform listeners about the removal of a child.

Parameters:

removedNode - the removed child
