DataTable Part

Is a DataTable allowed in EDT? Do I need to make some changes?

I am trying to build a table I can use to look up values from a dedicated service program with a string/char input. I believe I was able to do this in RBD.

The following code tells me that it cannot resolve contents (with or without the BasicTable stereotype).

package common;

DataTable RoastYieldFactors 

	fieldOne int;
	fieldTwo int;
	
	{contents = [ 
				[11,22], 
				[44, 68] 
				]
				}
End // End part



This code cannot resolve contents and will not allow the char definition.

package common;

DataTable RoastYieldFactors 

	fieldOne char(2);
	fieldTwo int;
	
	{contents = [ 
				["AA",22], 
				["BB", 68] 
				]
				}
End // End part

Nathan,

Data Tables are not supported in EDT at this time.

Brian or Someone:

Is there a typical method for looking up standard data in services?

It does not appear that the "in" opcode is supported. I am still trying to research alternatives to this. But even then I cannot put an array in a library. If I figure out how to search an array I guess I could put the array in a service and get to it from other services. Looks like I am just building a messy work around.

Do I have to build an sql table just to store some simple table lookup? For example I just want to look up a numeric value that is associated with a string. ("Factor", 32.45)

Thx,

Nathan Reed

Brian:

The juno vs indigo issues was causing the "in" operator issue (probably).

It works fine now that I am on idigo.

Sorry for being a pain.

Thx,

Nathan Reed

Perhaps I spoke too soon.

The code below does not give a syntax error so I thought it was going to work. But it will not generate. I get a

java.language.nullPointerException could not be found.

There is no sysvar to get the index so I am not sure this will work.

Does anyone know of a way to determine an index value from an array search?


package server;
service testService
	
	
	roastYieldDescription string[] = [ "7-Bone Roast", "Chuck Roast", "Chuck Eye Roast" ];		
	function calculateRoastYield()
	roastname string = "Chuck Roast";
	
	if((roastName in roastYieldDescription) == true) 
		stophere string = "";
	else
		orhere string = "";
	end		
	return;	
	end // End function	
end

Check this:

http://wiki.eclipse.org/EDT:EGL_Language_Operators_and_Expressions

Seems to indicate that "in" is planned for 1.0 but not before.

My guess then is that for now you'll have to write your own "in" like function where you iterate over the array.
