Field Detail

MAX_MAX_RESULTS

public static final int MAX_MAX_RESULTS

This is the recommended maximum number of 'max' results the system will allow you to return. This value is NOT enforced. ApplicationServiceGeneric often retrieves (startIndex + maxResults) number of results which breaks this MAX_MAX_RESULTS.

Constant Field Values

ALL_RESULTS

public static final int ALL_RESULTS

Flag to indicate that an EntityQuery should retrieve all results.

WARNING: using this flag could retrieve thousands or millions of entities. Misuse can cause massive performance problems. This flag should only ever be used in exceptional circumstances.

If you need to find "all" entities, then consider making multiple successive calls to Crowd to receive partial results. That way, the entire result set is never stored in memory on the Crowd server at any one time.
