Methods

dropBuffer

aggregatorPadDropBuffer

Arguments

:: (HasCallStack, MonadIO m, IsAggregatorPad a)

=> a

pad: the pad where to drop any pending buffer

-> m Bool

Returns: TRUE if there was a buffer queued in pad, or FALSE if not.

Drop the buffer currently queued in pad.

hasBuffer

aggregatorPadHasBuffer

Arguments

:: (HasCallStack, MonadIO m, IsAggregatorPad a)

=> a

pad: the pad to check the buffer on

-> m Bool

Returns: True if the pad has a buffer available as the next thing.

isEos

Arguments

:: (HasCallStack, MonadIO m, IsAggregatorPad a)

=> a

pad: an aggregator pad

-> m Bool

Returns: True if the pad is EOS, otherwise False.

peekBuffer

Arguments

:: (HasCallStack, MonadIO m, IsAggregatorPad a)

=> a

pad: the pad to get buffer from

-> m Buffer

Returns: A reference to the buffer in pad or NULL if no buffer was queued. You should unref the buffer after usage.
