  4. def apply(any: Any, dataType: DataType): GpuScalar

    Creates a GpuScalar from a 'Any' according to the DataType.

    Creates a GpuScalar from a 'Any' according to the DataType.

    If the Any is a cudf Scalar, it will be taken over by the returned GpuScalar, so no need to close it. But the returned GpuScalar should be closed to avoid memory leak.

  12. def columnVectorFromLiterals(seq: Seq[Any], elementType: DataType): ColumnVector

    Creates a cudf ColumnVector from the literal values in seq.

    Creates a cudf ColumnVector from the literal values in seq.

    seq

    the sequence of the literal values.

    elementType

    the data type of each value in the seq

    returns

    a cudf ColumnVector, its length is equal to the size of the seq.

  17. def from(v: Any, t: DataType): Scalar

    Creates a cudf Scalar from a 'Any' according to the DataType.

    Creates a cudf Scalar from a 'Any' according to the DataType.

    Many expressions (e.g. nodes handling strings and predictions) require a cudf Scalar created from a literal value to run their computations. We do not want to go through the GpuLiteral or the GpuScalar to get one.

    v

    the Scala value

    t

    the data type of the scalar

    returns

    a cudf Scalar. It should be closed to avoid memory leak.
