Class SchemaExporter

      atg.endeca.index.schema.SchemaExporter

public class SchemaExporter
extends PerApplicationExporter

This class uploads an Endeca schema data into a RecordStore using a RecordStoreDocumentSubmitter. It introspects the specified IndexingOutputConfig to generate its base schema, and then layers on any additional changes form the XML file specfied by the supplementalSchemaRecords property.

The schema is represented by a Records object that holds a Record-based representation of the schema, which is then uploaded via a RecordStoreDocumentSubmitter.

This class supports merging in supplemental/override information via the supplementalSchemaRecords property.
