Package com.singularsys.jep.configurableparser

Class RangeOperator

java.lang.Object

com.singularsys.jep.Operator

com.singularsys.jep.configurableparser.RangeOperator

All Implemented Interfaces:

PrintVisitor.PrintRulesI, Serializable

public class RangeOperator
extends Operator
implements PrintVisitor.PrintRulesI

Operators like [ x .. y ] with three symbols.

To add the operator use

  OperatorTable2 optab = new StandardOperatorTable2();
  Operator rangeOp = new RangeOperator("..", "[", "]", new Range(), Operator.BINARY+Operator.NOT_IN_PARSER);
  optab.insertOperator(OperatorTable2.SpecialOperators.RANGE , rangeOp, optab.getAssign());
  ConfigurableParser cp = new ConfigurableParserWithRange("..");
  Jep jep = new Jep(cp,optab);

Since:

Jep 4.1
