Examples of com.intersys.gds.DocumentType

com.intersys.gds.DocumentType
DocumentType is used to declare and access Document schema for a full schema version of GDS. In addition to the declaration of all currently supported types, it provides methods to create and access Document types and indices. GDS supports indexing of individual fields (compound indices are not currently supported. There is no limit on number of indices, but make sure to use them smartly. Indices will dramatically improve query performance but too many indices can also significantly slow down the inserts, since indexing is done synchronously.
