can-query-logic

A queryLogic that is used to perform calculations using set definition objects passed to getListData and getList. Needed to enable caching, request combining, real-time and other behaviors. By default no queryLogic is provided.

An example of the types of calculations behaviors will make using the queryLogic:

var queryLogic = new QueryLogic({
  identity: ['_uid'],
  keys: {
    _uid: Number
  }
});

var todoConnection = connect([...behaviors...],{
  queryLogic: queryLogic
});

todoConnection.queryLogic.memberIdentity({_uid: 5, ...}); //-> 5
todoConnection.id({_uid: 5, ...}); //-> 5
todoConnection.queryLogic.intersection(
  {page: {first: 0, last: 10}},
  {page: {first:  d5, last: 20}}); //-> {first:5, last:10}
