public ByteArraySeekableStream(byte[] buf)

Method Detail

seek

public void seek(long desired)
          throws IOException

Description copied from class: SeekableInputStream

Seek to the given offset from the start of the file. The next read() will be from that location. Can't seek past the end of the stream.

Specified by:

seek in class SeekableInputStream

Parameters:

desired - the desired offset

Throws:

IOException - Thrown if an error occurred while seeking inside the input stream.

getPos

public long getPos()
            throws IOException

Description copied from class: SeekableInputStream

Gets the current position in the input stream.

Specified by:

getPos in class SeekableInputStream

Returns:

current position in the input stream

Throws:

IOException - Thrown if an I/O error occurred in the underlying stream implementation while accessing the stream's position.

read

public int read()
         throws IOException

Specified by:

read in class InputStream

Throws:

IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Description copied from class: SeekableInputStream

Reads up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer.

Specified by:

read in class SeekableInputStream

Throws:

IOException

read

public int read(byte[] b)
         throws IOException

Overrides:

read in class InputStream

Throws:

IOException

skip

public long skip(long n)
          throws IOException

Overrides:

skip in class InputStream

Throws:

IOException

available

public int available()
              throws IOException

Overrides:

available in class InputStream

Throws:

IOException

mark

public void mark(int readlimit)

Overrides:

mark in class InputStream

reset

public void reset()
           throws IOException

Overrides:

reset in class InputStream

Throws:

IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class InputStream

close

public void close()
           throws IOException

Description copied from class: SeekableInputStream

Closes this input stream and releases any system resources associated with the stream.

The close method of InputStream does nothing.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in class SeekableInputStream

Throws:

IOException - if an I/O error occurs.
