question: public GeometryFunction find ( String name , int argCount ) { for ( Iterator i = functions . iterator ( ) ; i . hasNext ( ) ; ) { GeometryFunction func = ( GeometryFunction ) i . next ( ) ; String funcName = func . getName ( ) ; if ( funcName . equalsIgnoreCase ( name ) && func . getParameterTypes ( ) . length == argCount ) return func ; } return null ; }
target:  Finds the first function which matches the given name and argument count.
