Returns:

the information saved in the current string

addChild

value - the information that will be stored in the child node

type - the type of the child node

Returns:

the child node

clearChildren

public void clearChildren()

]

Overrides:

toString in class Object

subTreeToString

public String subTreeToString(String treePrefix,
 int prefixOccurance)
