Constructor Detail

Readable

public Readable(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

Read

@ByVal
public LongResult Read(@Cast(value="int64_t")
                              long nbytes,
                              Pointer out)

\brief Read data from current file position. Read at most nbytes from the current file position into out. The number of bytes read is returned.

Read

@ByVal
public BufferResult Read(@Cast(value="int64_t")
                                long nbytes)

\brief Read data from current file position. Read at most nbytes from the current file position. Less bytes may be read if EOF is reached. This method updates the current file position. In some cases (e.g. a memory-mapped file), this method may avoid a memory copy.

io_context

@Const
 @ByRef
public IOContext io_context()

EXPERIMENTAL: The IOContext associated with this file. By default, this is the same as default_io_context(), but it may be overriden by subclasses.
