gio.MemoryOutputStream — Streaming output operations on memory chunks
class gio.MemoryOutputStream(gio.OutputStream): |
gio.MemoryOutputStream
is a class for using arbitrary memory chunks as output for GIO streaming output operations.
gio.MemoryOutputStream()Returns : | a new
gio.MemoryOutputStream.
|
Creates a new
gio.MemoryOutputStream.
def get_contents()Returns : | the stream's data |
The get_contents() method gets any loaded data
from the ostream.
Note that the returned data may become invalid on the next write or truncate operation on the stream.
def get_data_size()Returns : | the number of bytes written to the stream |
The get_data_size() method returns the number
of bytes from the start up to including the last byte written in the
stream that has not been truncated away.
def get_size()Returns : | the number of bytes allocated for the data buffer |
The get_size() method gets the size of the
currently allocated data area (availible from
gio.MemoryOutputStream.get_contents()
).
Note that for growable streams the returned size may become invalid on the next write or truncate operation on the stream.
If you want the number of bytes currently written to the stream, use
gio.MemoryOutputStream.get_data_size().
