InAux

Returns true if the auxiliary input is completed (and closed) and from now on the same constant value will be returned. Similar to isDone on Main handlers, although an auxiliary handler will never call back directly if the input is closed.

The number of further input or output frames available.

Whether further input or output is available.

Returns the next input value and advances the internal offset. This may result in the old buffer being freed and a new buffer being grabbed, so one should always go back to check hasNext or available in the same loop, until the input is exhausted.

Returns the next input value without advancing the internal offset.
