Class MapPfmc

java.lang.Object

com.singularsys.jep.functions.PostfixMathCommand

com.singularsys.jep.functions.NaryFunction

com.singularsys.jep.misc.dictionary.MapPfmc

All Implemented Interfaces:

PostfixMathCommandI, PrintVisitor.PrintRulesI, Serializable

public class MapPfmc
extends NaryFunction
implements PrintVisitor.PrintRulesI

PostfixMathCommand for creating a Map. Parsing {'x':2, 'y':3} produces an ASTOpNode with the MapPfmc, each child is another ASTOpNode with the MapPfmc.MapEntryPfmc and two children, the key and value. Evaluating each child results in an MapPfmc.Entry record, these are added to a Map that is returned by evaluating the top node.

Since:

Jep 4.1
