toString

public java.lang.String toString()

Returns the string representation of the name of the current node.

This method can be overriden in a subclasse of SimpleNode to customize the way the node appears when the tree is dumped. If the output uses more than one line, override the toString(String) method, otherwise overriding this method is probably adequate.

Overrides:

toString in class java.lang.Object

Returns:

a String representing the name of the current node

See Also:

toString(String prefix)

toString

public java.lang.String toString(java.lang.String prefix)

Returns the string representation of the name of the current node plus the specified prefix string.

This method can be overriden in a subclasse of SimpleNode to customize the way the node appears when the tree is dumped. If the output uses more than one line, override this method, otherwise overriding the toString() method is probably adequate.

Parameters:

prefix - a String specifying the prefix string to add to the name of the current node

Returns:

a String representing the name of the current node plus the prefix string

See Also:

toString()

dump

public void dump(java.lang.String prefix)

Display all the nodes beginning at the current node and descending through all the children nodes.

Override this method to customize how the node dumps out its children.

Parameters:

prefix - a String specifying the prefix string to add to the name of each node
