GROOVY Procedure

Example: Define Classes

Features:

PROC GROOVY statement option:: CLASSPATH

SUBMIT command option: PARSEONLY

SUBMIT command

ENDSUBMIT command

The following three examples show how to use PROC GROOVY to define a class.

Program

Groovy code is run by default. If your script does not have any executable code, then an error is returned. The following example defines a class, but it does not have any executable code, and an error is returned.

proc groovy classpath=cp;
  submit;
    class Speaker {
      def say( word ) {
        println "----> \"${word}\""
      }
    }
  endsubmit;
quit;

Program

The following example shows how to define a class that can be run by including a main method.

proc groovy classpath=cp;
  submit;
    class Speaker {
      def Speaker() {
        println "----> ctor"
      }
      def main( args ) {
        println "----> main"
      }
    }
  endsubmit;
quit;

Program

The following example shows how to use the PARSEONLY option to avoid a run call. You can then use the new class in another execution of PROC GROOVY.

proc groovy classpath=cp;
  submit parseonly;
    class Speaker {
      def say( word ) {
        println "----> \"${word}\""
      }
    }
  endsubmit;
quit;

proc groovy classpath=cp;
  eval "s = new Speaker(); s.say( ""Hi"" )";
quit;
