Data Producers

Data Producers are configurable sources of data that can be processed by Data Consumers. Data Producers implement the ICollectionGateway interface. These objects acquire data from some source and transform it to one or more RTI IResultSets. Result sets are passed to consumers through the IGatewayListener interface. This interface is typically implemented by an ICollectionBuilder class that manages the flow of data between producers and consumers possibly in a multi-threaded fashion.

BIFFileGateway - Generates result sets from Verity Bulk Insert Format (BIF) files.
FileSystemGateway - Collection Gateway is responsible for collecting files.
FlatFileGateway - Reads a flat file or files to create sets of records (IResultSet) for indexing.
HTMLScraperGateway - Creates Result Set for processing from HTMLScraper output.
QueryProcessorGateway - Uses an SearchSource to generate results for indexing or other processing.
QueryProcessorXMLGateway - Builds XML records from a search source or sources. Uses a set of queries to generate results which are then formatted into XML records.
SimpleXMLGateway - Basic implementation of Collection Gateway that uses an XML DataSource.
- FileXMLDataSource - Implementation of IXMLDataSource that retrieves xml data from one or more files.
- FTPXMLDataSource - Implementation of IXMLDataSource that pulls files from an FTP host.
- RSSDataSource - Implementation of IXMLDataSource that acquires XML documents from an RSS Source.
