ParcelFileDescriptor.AutoCloseInputStream
public static class ParcelFileDescriptor.AutoCloseInputStream
extends FileInputStream
Known Direct Subclasses
|
An InputStream you can create on a ParcelFileDescriptor, which will take care of calling ParcelFileDescriptor.close()
for you when the stream is closed.

toString() Returns a string representation of the object. |
final void |
wait(long millis, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. |
final void |
wait(long millis) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed. |

Public methods
close
void close ()
Closes this file input stream and releases any system resources associated with the stream.
If this stream has an associated channel then the channel is closed as well.
read
int read ()
Reads a byte of data from this input stream. This method blocks if no input is yet available.
Returns |
int |
the next byte of data, or -1 if the end of the file is reached. |
read
int read (byte[] b,
int off,
int len)
Reads up to len
bytes of data from this input stream into an array of bytes. If len
is not zero, the method blocks until some input is available; otherwise, no bytes are read and 0
is returned.
Parameters |
b |
byte : the buffer into which the data is read. |
off |
int : the start offset in the destination array b |
len |
int : the maximum number of bytes read. |
Returns |
int |
the total number of bytes read into the buffer, or -1 if there is no more data because the end of the file has been reached. |
read
int read (byte[] b)
Reads up to b.length
bytes of data from this input stream into an array of bytes. This method blocks until some input is available.
Parameters |
b |
byte : the buffer into which the data is read. |
Returns |
int |
the total number of bytes read into the buffer, or -1 if there is no more data because the end of the file has been reached. |
