Detailed Description

A query specifies which objects you are interested in.

It is a combination of:

Bounds

Condition

Feature Ids

Order

Limit

All of these are optional. The query implementation must use all settings on the Query instance. For example, if both a bounds and a condition are specified, the query implementation must take both the bounds and the condition into account. Create an empty Query to get all objects. When both a condition and feature ids are provided in the Query the objects need to fulfill both.
