All Implemented Interfaces:

Serializable, Comparable<OperatorSymbol>, Constable

public enum OperatorSymbol
extends Enum<OperatorSymbol>

A Symbol is an abstraction of a token. In some cases there is a one-to-one correspondence between symbols and tokens (for example the token "!" and the symbol BANG. Often however the meaning of a token depends on context, and the symbol represents the deciphered meaning of the token, given its context.

Many symbols, but not all, represent XPath operators.
