Examples
getFunctionCalledName Basic Example

void function actualFunctionName() {
writeOutput( "actualFunctionName() was called as: #getFunctionCalledName()#<br>" );
}
writeOutput( "<hr><h4>Calling actualFunctionName()</h4>" );
actualFunctionName();
writeOutput( "<hr><h4>Calling actualFunctionName() via reference</h4>" );
referenceToFunction = actualFunctionName;
referenceToFunction();
Getters and Setters Example
Example of using getFunctionCalledName to create dynamic getters and setters
//callednamedemo.bx
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.bxm --->
<bx:script>
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>" );
</bx:script>
<!--- 20 --->Additional Examples
yell = ( Any name ) => {
echo( name );
dump( var=getFunctionCalledName(), label="Function was called as" );
};
yell( "yell" );
say = yell; // copy function
say( "say from " );
yell = say; // copy function again
yell( "yell from say" );
