All Implemented Interfaces:

LazyOperator, Operator

Enclosing class:

Expression

public abstract class Expression.Operator
extends AbstractOperator

Abstract definition of a supported operator. An operator is defined by its name (pattern), precedence, if it is left- or right-associative, if it is boolean and if it is unary (number of operands expected for the operation is 1 or 2).

Constructor Detail

Operator

public Operator(java.lang.String oper,
                int precedence,
                boolean leftAssoc,
                boolean booleanOperator,
                boolean unaryOperator)

Creates a new unary operator.

Parameters:

oper - The operator name (pattern).

precedence - The operators precedence.

leftAssoc - true if the operator is left associative, else false.

booleanOperator - Whether this operator is boolean.

unaryOperator - Whether this operator is unary.

Creates a new boolean operator.

Parameters:

oper - The operator name (pattern).

precedence - The operators precedence.
