Writes audio data to the mixer via this source data line. The requested number of bytes of data are read from the specified array, starting at the given offset into the array, and written to the data line's buffer. If the caller attempts to write more data than can currently be written (see
available
), this method blocks until the requested amount of data has been written. This applies even if the requested amount of data to write is greater than the data line's buffer size. However, if the data line is closed, stopped, or flushed before the requested amount has been written, the method no longer blocks, but returns the number of bytes written thus far.
The number of bytes that can be written without blocking can be ascertained using the available
method of the DataLine
interface. (While it is guaranteed that this number of bytes can be written without blocking, there is no guarantee that attempts to write additional data will block.)
The number of bytes to write must represent an integral number of sample frames, such that:
[ bytes written ] % [frame size in bytes ] == 0
The return value will always meet this requirement. A request to write a number of bytes representing a non-integral number of sample frames cannot be fulfilled and may result in an IllegalArgumentException
