View source for EDT:Working with custom types

This page contains code snippets for custom types.

Your custom types are based on these EGL classifiers: 

:[[#Delete|Delegate]], [[#Enumeration|Enumeration]], [[#ExternalType|ExternalType]], [[#Handler|Handler]], 
:[[#Interface|Interface]], [[#Library|Library]], [[#Program|Program]], [[#Record|Record]], [[#Service|Service]]

= Delegate  =

= <br> Enumeration  =

The following enumeration defines three possible values. See the [[#Program|example program]] for using this enumeration. 

<source lang="java">
enumeration colorEnumeration
	RED,
	GREEN,
	BLUE
end
</source> 

= <br> ExternalType  =

= <br> Handler  =

= <br> Interface  =

The following Interface type reflects the MyService type shown in [[#Service|Service]]: <source lang="java">
Interface IMyService
   Function calculate(theList INT[] IN) 
            returns(BIN (4,2));

   // other function prototypes are here
end
</source> 

= <br> Library  =

= <br> Program  =

This basic program uses the [[#Enumeration|sample enumeration]]. 

<source lang="java">
program prog
	
	// variables and constants can be here
	
	// this function is the entrypoint
	function main()
		printColorName(colorEnumeration.RED);
	end
	
	function printColorName(color colorEnumeration)
		case (color)
			when(colorEnumeration.RED)
				syslib.writestdout("red");
			when(colorEnumeration.GREEN)
				syslib.writestdout("green");
			when(colorEnumeration.BLUE)
				syslib.writestdout("blue");
			otherwise
				syslib.writestdout("unknown");
		end
	end
	
	// other functions can go here
end
</source>

= <br> Record  =

= <br> Service  =

<source lang="java">
Service MyService

   // variables and constants can be here

   function calculate(myScore Int[] in) returns (Decimal (4,2)) 

      numberOfScores, i, mySum Int;
      numberOfScores = myScore.getSize();
      	
      for (i from 1 to numberOfScores by 1)
         mySum = myScore[i] + mySum;	       
      end
    	      
      return(mySum/numberOfScores);
   end

   // other functions are here

end
