Query

public Query(String[] keyIds,
             Filter filters,
             String[] propIds,
             PropositionDefinition[] propDefs,
             QueryMode queryMode)

Creates new Query instance with a default identifier.

Parameters:

keyIds - An array of key IDs. If this is null then the query will include all keyIDs.

filters - A chain of filters. The first filter's getAnd method returns the second filter in the chain or null.

propIds - The proposition IDs that the query will try to derive.
