Description

QueryComponent is, after all this time, still not extendable. Overriding a simple method is mostly impossible due to members being private or usage of non-public classes. Copying all code to an external class is also not going to work because of this. This patch finally allows overriding QueryComponent methods such as createMainQuery and mergeIds.
