/**
|
|
* An object search
|
|
*
|
|
* Note: in the ancient times of iTop, a search was named after DBObjectSearch.
|
|
* When the UNION has been introduced, it has been decided to:
|
|
* - declare a hierarchy of search classes, with two leafs :
|
|
* - one class to cope with a single query (A JOIN B... WHERE...)
|
|
* - and the other to cope with several queries (query1 UNION query2)
|
|
* - in order to preserve forward/backward compatibility of the existing modules
|
|
* - keep the name of DBObjectSearch even if it a little bit confusing
|
|
* - do not provide a type-hint for function parameters defined in the modules
|
|
* - leave the statements DBObjectSearch::FromOQL in the modules, though DBSearch is more relevant
