  4. def adoptAndMakeSpillable(cb: ColumnarBatch): SpillableColumnarBatch

    Constructs SpillableColumnarBatch from ColumnarBatch cb.

    Constructs SpillableColumnarBatch from ColumnarBatch cb. The new SpillableColumnarBatch takes ownership of cb, so the caller should not be closing cb after the call. The returned SpillableColumnarBatch needs to be closed by the caller after use.

  11. def getTableSlice(tbl: Table, beginRow: Int, endRow: Int): Table

    Gets a rectangular slice of the specified cudf.Table, with rows [beginRow, endRow) of all its columns, and returns the result as a new cudf.Table.

    Gets a rectangular slice of the specified cudf.Table, with rows [beginRow, endRow) of all its columns, and returns the result as a new cudf.Table. The argument tbl is not closed by the function. The caller needs to close, or otherwise manage its lifetime. The returned Table is owned by the caller, and needs to be closed after use.

  12. def getTableSlice(tbl: Table, beginRow: Int, endRow: Int, beginCol: Int, endCol: Int): Table

    Gets a rectangular slice of the specified cudf.Table, with rows [beginRow, endRow) of columns [beginCol, endCol).

    Gets a rectangular slice of the specified cudf.Table, with rows [beginRow, endRow) of columns [beginCol, endCol). The argument tbl is not closed by the function. The caller needs to close, or otherwise manage its lifetime. The returned Table is owned by the caller, and needs to be closed after use.

  18. def sliceAndMakeSpillable(tbl: Table, rowBegin: Int, rowEnd: Int, dataTypes: Seq[DataType]): SpillableColumnarBatch

    Gets a rectangular slice of the specified cudf.Table, with rows [beginRow, endRow) of all its columns, and converts the result into a SpillableColumnarBatch.

    Gets a rectangular slice of the specified cudf.Table, with rows [beginRow, endRow) of all its columns, and converts the result into a SpillableColumnarBatch. The argument tbl is not closed by the function. The caller needs to close, or otherwise manage its lifetime. The returned SpillableColumnarBatch is owned by the caller, and needs to be closed after use.

  20. def toSpillableBatch(table: Table, types: Seq[DataType]): SpillableColumnarBatch

    Constructs a SpillableColumnarBatch from the table and types specified.

    Constructs a SpillableColumnarBatch from the table and types specified. The argument table is not closed by this function. The resultant SpillableColumnarBatch needs to be closed by the caller after use.

  22. def toTable(cb: ColumnarBatch): Table

    Shorthand function to construct a cudf.Table from a ColumnarBatch.

    Shorthand function to construct a cudf.Table from a ColumnarBatch. The columns in the ColumnarBatch will have their reference counts incremented, when the new Table is constructed. Both the argument and the returned Table need to be closed by the caller, after use.
