Constructor Detail

FixedSizeBufferWriter

public FixedSizeBufferWriter(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

FixedSizeBufferWriter

public FixedSizeBufferWriter(@SharedPtr
                             ArrowBuffer buffer)

Input buffer must be mutable, will abort if not

Method Detail

Close

@ByVal
public Status Close()

Description copied from class: FileInterface

\brief Close the stream cleanly For writable streams, this will attempt to flush any pending data before releasing the underlying resource. After Close() is called, closed() returns true and the stream is not available for further operations.

Overrides:

Close in class FileInterface

closed

@Cast(value="bool")
public boolean closed()

Description copied from class: FileInterface

\brief Return whether the stream is closed

Overrides:

closed in class FileInterface

Seek

@ByVal
public Status Seek(@Cast(value="int64_t")
                           long _position)

Tell

@ByVal
public LongResult Tell()

Description copied from class: FileInterface

\brief Return the position in this stream

Overrides:

Tell in class FileInterface

Write

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

WriteAt

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

\endcond

Overrides:

WriteAt in class WritableFile

set_memcopy_threads

public void set_memcopy_threads(int num_threads)

set_memcopy_blocksize

public void set_memcopy_blocksize(@Cast(value="int64_t")
                                  long blocksize)

set_memcopy_threshold

public void set_memcopy_threshold(@Cast(value="int64_t")
                                  long threshold)
