public abstract Class MasterDetailProcessor

extends AbstractMasterDetailProcessor<ParsingContext>
Class Inheritance
Imports
com.univocity.parsers.common.*, com.univocity.parsers.common.processor.core.*, com.univocity.parsers.conversions.*
A RowProcessor implementation for associating rows extracted from any implementation of AbstractParser into MasterDetailRecord instances.

For each row processed, a call to MasterDetailProcessor#isMasterRecord(String[], Context) will be made to identify whether or not it is a master row.

The detail rows are automatically associated with the master record in an instance of MasterDetailRecord.

When the master record is fully processed (i.e. MasterDetailRecord contains a master row and all associated detail rows), it is sent to the user for processing in MasterDetailProcessor#masterDetailRecordProcessed(MasterDetailRecord, Context).

Note

this class extends ObjectRowProcessor and value conversions provided by Conversion instances are fully supported.
