Interface DtmfStream.SampleSource

Enclosing class:

DtmfStream

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface DtmfStream.SampleSource

A source of double PCM samples for DtmfStream.fromSource(SampleSource, DtmfConfig). Callers implement this as a functional interface, typically a lambda wrapping a file, socket, or pre-buffered array.

The return value follows the InputStream convention: a non-negative integer is the number of samples written into buffer starting at offset, and -1 signals end-of-stream.

Method Summary

int	readInto(double[] buffer, int offset, int length)	Read up to length samples into buffer[offset .. offset + length).

Method Details

readInto

int readInto(double[] buffer,
 int offset,
 int length)

Read up to length samples into buffer[offset .. offset + length).

Parameters:

buffer - destination buffer; non-null

offset - starting index; 0 <= offset <= buffer.length

length - maximum number of samples to write; 0 <= length && offset + length <= buffer.length

Returns:

the number of samples written (0 <= n <= length), or -1 to signal end-of-stream
