Description

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.

Synopsis

newtype FilterInputStream = FilterInputStream (ManagedPtr FilterInputStream)
class GObject o => IsFilterInputStream o
toFilterInputStream :: (MonadIO m, IsFilterInputStream o) => o -> m FilterInputStream
noFilterInputStream :: Maybe FilterInputStream
filterInputStreamGetBaseStream :: (HasCallStack, MonadIO m, IsFilterInputStream a) => a -> m InputStream
filterInputStreamGetCloseBaseStream :: (HasCallStack, MonadIO m, IsFilterInputStream a) => a -> m Bool
filterInputStreamSetCloseBaseStream :: (HasCallStack, MonadIO m, IsFilterInputStream a) => a -> Bool -> m ()
constructFilterInputStreamBaseStream :: (IsFilterInputStream o, IsInputStream a) => a -> IO (GValueConstruct o)
getFilterInputStreamBaseStream :: (MonadIO m, IsFilterInputStream o) => o -> m InputStream
constructFilterInputStreamCloseBaseStream :: IsFilterInputStream o => Bool -> IO (GValueConstruct o)
getFilterInputStreamCloseBaseStream :: (MonadIO m, IsFilterInputStream o) => o -> m Bool
setFilterInputStreamCloseBaseStream :: (MonadIO m, IsFilterInputStream o) => o -> Bool -> m ()

toFilterInputStream :: (MonadIO m, IsFilterInputStream o) => o -> m FilterInputStream Source #

Cast to FilterInputStream, for types for which this is known to be safe. For general casts, use castTo.

noFilterInputStream :: Maybe FilterInputStream Source #

A convenience alias for Nothing :: Maybe FilterInputStream.

Methods

getBaseStream

filterInputStreamGetBaseStream Source #

Arguments

:: (HasCallStack, MonadIO m, IsFilterInputStream a)
=> a	`stream`: a `FilterInputStream`.
-> m InputStream	Returns: a `InputStream`.

Gets the base stream for the filter stream.

getCloseBaseStream

filterInputStreamGetCloseBaseStream Source #

Arguments

:: (HasCallStack, MonadIO m, IsFilterInputStream a)
=> a	`stream`: a `FilterInputStream`.
-> m Bool	Returns: `True` if the base stream will be closed.

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

setCloseBaseStream

filterInputStreamSetCloseBaseStream Source #

Arguments

:: (HasCallStack, MonadIO m, IsFilterInputStream a)
=> a	`stream`: a `FilterInputStream`.
-> Bool	`closeBase`: `True` to close the base stream.
-> m ()

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

Properties

baseStream

No description available in the introspection data.

constructFilterInputStreamBaseStream :: (IsFilterInputStream o, IsInputStream a) => a -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “base-stream” property. This is rarely needed directly, but it is used by new.

getFilterInputStreamBaseStream :: (MonadIO m, IsFilterInputStream o) => o -> m InputStream Source #

Get the value of the “base-stream” property. When overloading is enabled, this is equivalent to

get filterInputStream #baseStream

closeBaseStream

No description available in the introspection data.

constructFilterInputStreamCloseBaseStream :: IsFilterInputStream o => Bool -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “close-base-stream” property. This is rarely needed directly, but it is used by new.

getFilterInputStreamCloseBaseStream :: (MonadIO m, IsFilterInputStream o) => o -> m Bool Source #

Get the value of the “close-base-stream” property. When overloading is enabled, this is equivalent to

get filterInputStream #closeBaseStream

setFilterInputStreamCloseBaseStream :: (MonadIO m, IsFilterInputStream o) => o -> Bool -> m () Source #

Set the value of the “close-base-stream” property. When overloading is enabled, this is equivalent to

set filterInputStream [ #closeBaseStream := value ]
