1 /** Rules that return more than a single value must return an object 2 * containing all the values. Besides the properties defined in 3 * RuleLabelScope.predefinedRulePropertiesScope there may be user-defined 4 * return values. This class simply defines the minimum properties that 5 * are always defined and methods to access the others that might be 6 * available depending on output option such as template and tree. 7 * 8 * Note text is not an actual property of the return value, it is computed 9 * from start and stop using the input stream's toString() method. I 10 * could add a ctor to this so that we can pass in and store the input 11 * stream, but I'm not sure we want to do that. It would seem to be undefined 12 * to get the .text property anyway if the rule matches tokens from multiple 13 * input streams. 14 * 15 * I do not use getters for fields of objects that are used simply to 16 * group values such as this aggregate. The getters/setters are there to 17 * satisfy the superclass interface. 18 */ 19 org.antlr.runtime.ParserRuleReturnScope = function() {}; 20 org.antlr.runtime.RuleReturnScope = function() {}; 21 22 org.antlr.lang.extend(org.antlr.runtime.ParserRuleReturnScope, 23 org.antlr.runtime.RuleReturnScope, 24 { 25 getStart: function() { return this.start; }, 26 getStop: function() { return this.stop; } 27 }); 28
