Description: Reference for Gio.FilterInputStream

### Class

# GioFilterInputStream

#### Description [src]

    abstract class Gio.FilterInputStream : Gio.InputStream
    {
      base_stream: GInputStream*
    }

Base class for input stream implementations that perform some kind of filtering operation on a base stream. Typical examples of filtering operations are character set conversion, compression and byte order flipping.

#### Instance methods

###### g_filter_input_stream_get_base_stream

Gets the base stream for the filter stream.

###### g_filter_input_stream_get_close_base_stream

Returns whether the base stream will be closed when `stream` is closed.

###### g_filter_input_stream_set_close_base_stream

Sets whether the base stream will be closed when `stream` is closed.

##### Methods inherited from GInputStream (19)

###### g_input_stream_clear_pending

Clears the pending flag on `stream`.

###### g_input_stream_close

Closes the stream, releasing resources related to it.

###### g_input_stream_close_async

Requests an asynchronous closes of the stream, releasing resources related to it. When the operation is finished `callback` will be called. You can then call `g_input_stream_close_finish()` to get the result of the operation.

###### g_input_stream_close_finish

Finishes closing a stream asynchronously, started from g_input_stream_close_async().

###### g_input_stream_has_pending

Checks if an input stream has pending actions.

###### g_input_stream_is_closed

Checks if an input stream is closed.

###### g_input_stream_read

Tries to read `count` bytes from the stream into the buffer starting at `buffer`. Will block during this read.

###### g_input_stream_read_all

Tries to read `count` bytes from the stream into the buffer starting at `buffer`. Will block during this read.

###### g_input_stream_read_all_async

Request an asynchronous read of `count` bytes from the stream into the buffer starting at `buffer`.

since: 2.44

###### g_input_stream_read_all_finish

Finishes an asynchronous stream read operation started with `g_input_stream_read_all_async()`.

since: 2.44

###### g_input_stream_read_async

Request an asynchronous read of `count` bytes from the stream into the buffer starting at `buffer`. When the operation is finished `callback` will be called. You can then call `g_input_stream_read_finish()` to get the result of the operation.

###### g_input_stream_read_bytes

Like g_input_stream_read(), this tries to read `count` bytes from the stream in a blocking fashion. However, rather than reading into a user-supplied buffer, this will create a new `GBytes` containing the data that was read. This may be easier to use from language bindings.

since: 2.34

###### g_input_stream_read_bytes_async

Request an asynchronous read of `count` bytes from the stream into a new `GBytes`. When the operation is finished `callback` will be called. You can then call `g_input_stream_read_bytes_finish()` to get the result of the operation.

since: 2.34

###### g_input_stream_read_bytes_finish

Finishes an asynchronous stream read-into-`GBytes` operation.

since: 2.34

###### g_input_stream_read_finish

Finishes an asynchronous stream read operation.

###### g_input_stream_set_pending

Sets `stream` to have actions pending. If the pending flag is already set or `stream` is closed, it will return `FALSE` and set `error`.

###### g_input_stream_skip

Tries to skip `count` bytes from the stream. Will block during the operation.

###### g_input_stream_skip_async

Request an asynchronous skip of `count` bytes from the stream. When the operation is finished `callback` will be called. You can then call `g_input_stream_skip_finish()` to get the result of the operation.

###### g_input_stream_skip_finish

Finishes a stream skip operation.

##### Methods inherited from GObject (43)

Please see GObject for a full list of methods.

#### Properties

###### Gio.FilterInputStream:base-stream

The underlying base stream on which the I/O ops will be done.

###### Gio.FilterInputStream:close-base-stream

Whether the base stream should be closed when the filter stream is closed.

#### Signals

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
