RapidsHostColumnBuilder

final class RapidsHostColumnBuilder extends AutoCloseable

This is a copy of the cudf HostColumnVector.ColumnBuilder class. Moving this here to allow for iterating on host memory oom handling.

    Appends bytes to a LIST of INT8/UINT8

  16. def appendByteList(value: Array[Byte]): RapidsHostColumnBuilder

    Appends byte to a LIST of INT8/UINT8

  17. def appendDecimal128(binary: Array[Byte]): RapidsHostColumnBuilder

    Accepts a byte array containing the two's-complement representation of the unscaled value, which is in big-endian byte-order.

    Accepts a byte array containing the two's-complement representation of the unscaled value, which is in big-endian byte-order. Then, transforms it into the representation of cuDF Decimal128 for appending. This method is more efficient than append(BigInteger unscaledVal) if we can directly access the two's-complement representation of a BigDecimal without encoding via the method toByteArray.

  29. def endList(): RapidsHostColumnBuilder

    If you want to build up a list column you can get builder.getChild(0) and append to than, then when you are done call endList and everything that was appended to that builder will now be in the next list.

    If you want to build up a list column you can get builder.getChild(0) and append to than, then when you are done call endList and everything that was appended to that builder will now be in the next list. Do not start to append to the child and then append a null to this without ending the list first or you might not get the results that you expected.

    returns

    this for chaining.

  30. def endStruct(): RapidsHostColumnBuilder

    If you want to build up a struct column you can get each child builder.getChild(N) and append to all of them, then when you are done call endStruct to update this builder.
