Interface TableListener

All Known Implementing Classes:
AbstractTableListener
public interface TableListener
Listener which can provided to an API which "constructs" a table (for example in ReportService) to allow for streaming management of table data, rather than bringing all into memory at once.

  • Method Summary

    Modifier and Type Method Description
    void beginTable​(TableMetaData tableMetaData)
    This event is fired just after the TableMetaData is constructed and before TableRows are constructed.
    void endTable()
    This event is fired when all TableRows are constructed to allow implementors to perform cleanup operations.
    void processRow​(TableRow tableRow)
    This event is fired sequentially as each TableRow is constructed; interested parties can listen to this method to process each row.

  • Method Details

    • beginTable

      void beginTable​(TableMetaData tableMetaData) throws TableListenerException
      This event is fired just after the TableMetaData is constructed and before TableRows are constructed.
      Parameters:
      tableMetaData - describes the table structure
      Throws:
      TableListenerException - - processing will abort if this exception is thrown.

    • processRow

      void processRow​(TableRow tableRow) throws TableListenerException
      This event is fired sequentially as each TableRow is constructed; interested parties can listen to this method to process each row.
      Parameters:
      tableRow - row being processed
      Throws:
      TableListenerException - - processing will abort if this exception is thrown.

    • endTable

      void endTable() throws TableListenerException
      This event is fired when all TableRows are constructed to allow implementors to perform cleanup operations.
      Throws:
      TableListenerException - - processing will abort if this exception is thrown.
