Hi All,
I need help with this code in ESQL.
I have three functions func1(A, B, C), func2(A, B, C) and func3(A, B, C) in my ESQL code.
Now in my ESQL main code I get a value in an environment variable say
Environment.Variable.tobecalled which tells gives me the function name to be called.
It can be either Environment.Variable.tobecalled = func1
So, if I have to call the function specified in environment variable, how do I do it
I wanted something like
CALL Environment.Variable.tobecalled (A, B , C)
Is there any way to do it without using if else? |

You could use a CASE statement, or an EVAL statement. However the EVAL statement has a performance hit...

I thought that this sort of thing went out of fashion years ago.
It smacks of 'Data Driven' Programming at its most extreme.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

This sounds like a very bad idea. You mentioned avoiding IF THEN ELSE, why can't you use that construct (or a CASE statement) ?

You could use RouteToLabel , use the LE to set the label node to propagate the message to the appropriate ComputeNode , basis the value that's coming in your message..
