Predicate.extendBinaryPredicateFn missing in latest breeze-client

[tschettler]

In 1.x versions of breeze-client, there was a Predicate.extendBinaryPredicateFn method. This has been commented out in the latest version of breeze-client (src/predicate.ts#L201):

  // TODO: determine if/where this is used.
  // static extendBinaryPredicateFn(opMap: IOpMap, visitorFn: any) {

This method was added to breeze.js in version 1.5 (Breeze/breeze.js@89c3e10) by @jtraband.

I was using this method to extend upon the built-in binary predicate operators in breeze. Can this method be restored?

Thanks!

Yes! Can you give me an example of how you use it? We have no tests for this right now.

[tschettler]

Sure! I would use it to allow breeze to recognize binary functions available in OData 4. This example would allow the add operator:

Predicate.extendBinaryPredicateFn({'add': { aliases: ['+', 'plus']}});

Which would allow queries like this:
http://host/service/Products?$filter=Price add 2.45 eq 5.00

I see. Then how would you compose the predicate (where clause)?
