Class ASTPtOrderedRecordConstructNode

java.lang.Object

ptolemy.data.expr.ASTPtRootNode

ptolemy.data.expr.ASTPtRecordConstructNode

ptolemy.data.expr.ASTPtOrderedRecordConstructNode

All Implemented Interfaces:

java.lang.Cloneable, Node

public class ASTPtOrderedRecordConstructNode
extends ASTPtRecordConstructNode

The parse tree created from the expression string consists of a hierarchy of node objects. This class represents record construction using the following syntax: {foo = "abc", bar = 1}. The result of parsing and evaluating this expression is a record token with two fields: a field foo containing a StringToken of value "abc", and a field bar containing a IntToken of value 1.
