question: public static < T > T withWriter ( Path self , String charset , @ ClosureParams ( value = SimpleType . class , options = "java.io.Writer" ) Closure < T > closure ) throws IOException { return withWriter ( self , charset , false , closure ) ; }
target:  Creates a new BufferedWriter for this file, passes it to the closure, and ensures the stream is flushed and closed after the closure returns. The writer will use the given charset encoding, but will not write a BOM.
