Returns the typed value for this node as determined when parsing the expression

Returns:

the typed value (may also be a String)

isBracketed

public boolean isBracketed()

True if the expression that generated this node was inside square brackets.

getNext

public Node getNext()

Gets the next node in the expression. Returns null if this is the terminal node.

setNext

protected void setNext(Node next)

Sets the next node in the expression.

getPrevious

public Node getPrevious()

Gets the previous node in the expression. Returns null if this is the first node.

setPrevious

protected void setPrevious(Node previous)

Sets the previous node in the expression.
