CategoryFunction syntaxGetFunctionCalledName() HistoryColdFusion 9: Added this function UsageThis function can be used to return data from CFCs by simulating getters and setters. This applies only if the CFC does not use implicit getters and setters provided by ColdFusion 9. ExampleThe following example shows how you can use this function to return data without defining explicit setters and getters: //callednamedemo.cfc component { variables.x1 = 1; variables.y1 = 2; function init() { return this; } function get() { var name = getFunctionCalledName(); return variables[mid(name,4,len(name)-3)]; } function set(value) { var name = getFunctionCalledName(); variables[mid(name,4,len(name)-3)] = value; } this.getX1 = get; this.getY1 = get; this.setX1 = set; this.setY1 = set; } <!--- calledname.cfm ---> <cfscript> function test() { return getFunctionCalledName(); } WriteOutput(test() & "<br>"); // test a = test; WriteOutput(variables.a() & "<br>"); // a o = new callednamedemo(); // shows *real* methods get(), SetX1() and getY1(), etc. writeDump(o); o.setX1(10); o.setY1(20); WriteOutput(o.getX1() & "<br>"); // 10 WriteOutput(o.getY1() & "<br>") ; // 20 </cfscript> |
