  13. def copyBuffer(buffer: RapidsBuffer, memoryBuffer: MemoryBuffer, stream: Stream): RapidsBufferBase

    Adds an existing buffer from another store to this store.

    Adds an existing buffer from another store to this store. The buffer must already have an active reference by the caller and needs to be eventually closed by the caller (i.e.: this method will not take ownership of the incoming buffer object). This does not need to update the catalog, the caller is responsible for that.

    buffer

    data from another store

    memoryBuffer

    memory buffer obtained from the specified Rapids buffer. The ownership for memoryBuffer is transferred to this store. The store may close memoryBuffer if necessary.

    stream

    CUDA stream to use for copy or null

    returns

    new buffer that was created

    Definition Classes
    RapidsBufferStore
  14. def createBuffer(incoming: RapidsBuffer, incomingBuffer: MemoryBuffer, stream: Stream): RapidsBufferBase

    Create a new buffer from an existing buffer in another store.

    Create a new buffer from an existing buffer in another store. If the data transfer will be performed asynchronously, this method is responsible for adding a reference to the existing buffer and later closing it when the transfer completes.

    stream

    CUDA stream to use or null

    returns

    new buffer tracking the data in this store

    DO NOT close the buffer unless adding a reference!

    createBuffer impls should synchronize against stream before returning, if needed.
