|Constructor and Description|
|Modifier and Type||Method and Description|
Closes this stream.
Invoked when the garbage collector has detected that this instance is no longer reachable.
Reads a single byte from this stream and returns it as an integer in the range from 0 to 255.
Reads at most
public MicrophoneInputStream(int sampleRate, int fifoDepth) throws IOException
sampleRate- sample rate of the microphone, typically 11025 or 8000.
fifoDepth- depth of the real time fifo, measured in sampleRate clock ticks. This determines how long an application may delay before losing data.
public int read() throws IOException
public int read(byte b) throws IOException
read(buffer, 0, buffer.length).
public int read(byte b, int offset, int length) throws IOException
lengthbytes from this stream and stores them in the byte array
b- the byte array in which to store the bytes read.
offset- the initial position in
bufferto store the bytes read from this stream.
length- the maximum number of bytes to store in
IOException- if the stream is closed or another IOException occurs.
public void close() throws IOException
protected void finalize() throws Throwable
Note that objects that override
finalize are significantly more expensive than
objects that don't. Finalizers may be run a long time after the object is no longer
reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup.
Note also that finalizers are run on a single VM-wide finalizer thread,
so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary
for a class that has a native peer and needs to call a native method to destroy that peer.
Even then, it's better to provide an explicit
close method (and implement
Closeable), and insist that callers manually dispose of instances. This
works well for something like files, but less well for something like a
where typical calling code would have to deal with lots of temporaries. Unfortunately,
code that creates lots of temporaries is the worst kind of code from the point of view of
the single finalizer thread.
If you must use finalizers, consider at least providing your own
ReferenceQueue and having your own thread process that queue.
Unlike constructors, finalizers are not automatically chained. You are responsible for
Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
