Method Detail

readInternal

protected final void readInternal(byte[] b,
                                  int offset,
                                  int len)
                           throws IOException

InputStream methods

Specified by:

readInternal in class InputStream

Parameters:

b - the array to read bytes into

offset - the offset in the array to start storing bytes

len - the number of bytes to read

Throws:

IOException

close

public final void close()
                 throws IOException

Description copied from class: InputStream

Closes the stream to futher operations.

Specified by:

close in class InputStream

Throws:

IOException

seekInternal

protected final void seekInternal(long position)
                           throws IOException

Random-access methods

Specified by:

seekInternal in class InputStream

Throws:

IOException

See Also:

InputStream.readInternal(byte[],int,int)

finalize

protected final void finalize()
                       throws IOException

Overrides:

finalize in class Object

Throws:

IOException

clone

public Object clone()

Description copied from class: InputStream

Returns a clone of this stream.

Clones of a stream access the same data, and are positioned at the same point as the stream they were cloned from.

Expert: Subclasses must ensure that clones may be positioned at different points in the input from each other and from the stream they were cloned from.

Overrides:

clone in class InputStream

isFDValid

boolean isFDValid()
            throws IOException

Method used for testing. Returns true if the underlying file descriptor is valid.

Throws:

IOException
