Public Constructors

public FileDescriptorReadOnlyFilter (int mode, ParcelFileDescriptor pfd)

public FileDescriptorReadOnlyFilter (int mode, FileDescriptorReadOnlyFilter fileDescriptorFilter)

Public Methods

public void close ()

public long onCreateInputIterator (Object o)

public void onDestroy (Object o)

public long onFlush (Object o)

The abstract function in which the output data is flushed.

Parameters
o The user data from passed in via #CustomFilter(int, Object).
Returns
  • If successful, the value is 0; otherwise, it is non-zero.

public long onRead (byte[] bytes, Object o)

The abstract function in which the input data are read.

Parameters
bytes The buffer to contain the data to read, which has already been allocated.
o The user data from passed in via #CustomFilter(int, Object).
Returns
  • The number of bytes read. It should return 0 if it fails or reaches the end of the input stream.

public long onSeek (long offset, int origin, Object o)

The abstract function in which the position indicator of the filter is set.

Parameters
offset Number of bytes to offset from origin. A positive value implies the indicator is moved forward, and a negative value implies the indicator is moved backward.
origin Position from where offset is added. It is specified by one of the following: SEEK_SET, SEEK_CUR, SEEK_END.
o The user data from passed in via #CustomFilter(int, Object).
Returns
  • The new position of the indicator set. If successful, the value is 0; otherwise, it is non-zero.

public long onTell (Object o)

The abstract function in which the position indicator of the filter is queried.

Parameters
o The user data from passed in via #CustomFilter(int, Object).
Returns
  • The position of the indicator.

public long onWrite (byte[] bytes, Object o)

The abstract function in which the data are output.

Parameters
bytes The buffer to contain the data to write out.
o The user data from passed in via #CustomFilter(int, Object).
Returns
  • The number of bytes successfully written.
