public class OpenJMSContext

extends javax.swing.tree.DefaultMutableTreeNode

implements OpenJMSNode

This class controls all dispay characteristics and menus related to a queue/topic object. Currently only add/delete, edit and purge is supported. Add is added from the OpenJMSServer node. Only one menu is created for all queue/topics since it is modal, it can be shared by all the nodes.

Constructor Detail

OpenJMSContext

public OpenJMSContext(java.lang.String contextName,
                      java.lang.String parentName,
                      javax.swing.JTree tree)

The constructor gets its unique name for this context and a reference to its parent tree.

If this is the first context call, the menu for all contexts is created.

Parameters:

contextName - This context name.

tree - The parent tree this context belongs to.

Method Detail

createCommands

protected void createCommands()

getAllowsChildren

public boolean getAllowsChildren()

Children are allowed for all contexts

getAllowsChildren in class javax.swing.tree.DefaultMutableTreeNode

Returns:

boolean Always returns true.

isLeaf

public boolean isLeaf()

Overrides:

isLeaf in class javax.swing.tree.DefaultMutableTreeNode

Returns:

boolean true if no objects are registered.

update

public void update()

As a performance enhancement, no child is added to the context until after it is expanded.
