Constructor Detail

DataSourceTreeNode

public DataSourceTreeNode()

Creates a tree node that has no parent and no children, but which allows children.

DataSourceTreeNode

public DataSourceTreeNode(Object userObject)

Creates a tree node with no parent, no children, but which allows children, and initializes it with the specified user object.

Parameters:

userObject - an Object provided by the user that constitutes the node's data

DataSourceTreeNode

public DataSourceTreeNode(Object userObject,
                          boolean allowsChildren)

Creates a tree node with no parent, no children, initialized with the specified user object, and that allows children only if specified.

Parameters:

userObject - an Object provided by the user that constitutes the node's data

allowsChildren - if true, the node is allowed to have child nodes -- otherwise, it is always a leaf node
