Class GTCurrentConnectionsDataSource

  • All Implemented Interfaces:
    MutableTableDataSource, TableDataSource

    final class GTCurrentConnectionsDataSource
    extends GTDataSource
    An implementation of MutableTableDataSource that presents the current list of connections on the database.

    NOTE: This is not designed to be a long kept object. It must not last beyond the lifetime of a transaction.

    • Field Detail

      • key_value_pairs

        private java.util.ArrayList key_value_pairs
        The list of info keys/values in this object.
      • DEF_DATA_TABLE_DEF

        static final DataTableDef DEF_DATA_TABLE_DEF

    • Method Detail

      • getRowCount

        public int getRowCount()
        Description copied from interface: TableDataSource
        Returns the number of rows in this data source.

        NOTE: Returns 'n' - getCellContents(column, row) is not necessarily valid for row = [0..n]. Use 'rowEnumerator' to generate an iterator for valid row values over this data source.

        Specified by:
        getRowCount in interface TableDataSource
        Specified by:
        getRowCount in class GTDataSource
      • getCellContents

        public TObject getCellContents​(int column,
                                       int row)
        Description copied from interface: TableDataSource
        Returns an object that represents the information in the given cell in the table. This may be an expensive operation, so calls to it should be kept to a minimum. Note that the offset between two rows is not necessarily 1. Use 'rowEnumeration' to create a row iterator.
        Specified by:
        getCellContents in interface TableDataSource

        getCellContents in class GTDataSource
      • dispose

        public void dispose()
        Description copied from interface: MutableTableDataSource
        Disposes this table data source. After this method is called, most use of this object is undefined, except for the 'getCellContent' and 'compareCellContent' methods which are valid provided the source is under a root lock.
