Class OperatorTable<E>

java.lang.Object

jfun.parsec.OperatorTable<E>

All Implemented Interfaces:

java.io.Serializable

public final class OperatorTable<E>
extends java.lang.Object
implements java.io.Serializable

This class is used to describe operator information. Operators have precedences. the higher the precedence number, the higher the precedence. For the same precedence, prefix > postfix > left infix > right infix > non-associative infix.
