Method Summary

Modifier and Type	Method and Description
Status	Flush() \brief Flush buffered bytes, if any
Status	Write(ArrowBuffer data) \brief Write the given data to the stream Since the Buffer owns its memory, this method can avoid a copy if buffering is required.
Status	Write(Pointer data, long nbytes) \brief Write the given data to the stream This method always processes the bytes in full.

Method Detail

Write

@ByVal
public Status Write(@Const
                            Pointer data,
                            @Cast(value="int64_t")
                            long nbytes)

\brief Write the given data to the stream This method always processes the bytes in full. Depending on the semantics of the stream, the data may be written out immediately, held in a buffer, or written asynchronously. In the case where the stream buffers the data, it will be copied. To avoid potentially large copies, use the Write variant that takes an owned Buffer.

Write

@ByVal
public Status Write(@SharedPtr
                            ArrowBuffer data)

\brief Write the given data to the stream Since the Buffer owns its memory, this method can avoid a copy if buffering is required. See Write(const void*, int64_t) for details.

Flush

@ByVal
public Status Flush()

\brief Flush buffered bytes, if any
