com.singularsys.jep.configurableparser.TernaryOperator

All Implemented Interfaces:

PrintVisitor.PrintRulesI, java.io.Serializable

public class TernaryOperator
extends Operator
implements PrintVisitor.PrintRulesI

A class representing a ternary operator, for example x?y:z. These are represented by a linked pair of operators, a TernaryOperator and the inner class RhsTernaryOperator.

Constructor Detail

TernaryOperator

public TernaryOperator(java.lang.String name,
                       java.lang.String lhsSymbol,
                       java.lang.String rhsSymbol,
                       PostfixMathCommandI pfmc,
                       int flags)

Create a Ternary operator. Precedence level set later.

Parameters:

name - verbose name for operator

lhsSymbol - symbol for left hand operator, typically "?"

rhsSymbol - symbol for right hand operator, typically ":"

pfmc - function implementing the operation, typically TernaryConditional

flags - status flags, typically Operator.TERNARY

TernaryOperator

public TernaryOperator(java.lang.String name,
                       java.lang.String lhsSymbol,
                       java.lang.String rhsSymbol,
                       PostfixMathCommandI pfmc,
                       int flags,
                       int precedence)

Create a Ternary operator

Parameters:

name - verbose name for operator

lhsSymbol - symbol for left hand operator, typically "?"

rhsSymbol - symbol for right hand operator, typically ":"

pfmc - function implementing the operation, typically TernaryConditional

flags - status flags, typically Operator.TERNARY

precedence - precedence level

Method Detail

getRhsSymbol

public java.lang.String getRhsSymbol()

Get symbol used to for righthand operator

Returns:

the symbol

getRhsOperator

public TernaryOperator.RhsTernaryOperator getRhsOperator()

setPrecedence

public void setPrecedence(int i)

Description copied from class: Operator

Set the precedence of the operator. Lower values correspond to tighter binding, that is * gives a lower value than + and 1+2*3 is 1+(2*3).

Overrides:

setPrecedence in class Operator

Parameters:

i - the precedence

append

public void append(Node node,
                   PrintVisitor pv)
            throws JepException

Description copied from interface: PrintVisitor.PrintRulesI

The method called to append data for the rule.

Specified by:

append in interface PrintVisitor.PrintRulesI

Parameters:

node - the node to print

pv - the PrintVisitor

Throws:

JepException - on error

Since:

4.0
