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

Public constructors
Public methods
close
public 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
public 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
public 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
public 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. |
