Method Detail

getBytesRead

public long getBytesRead()
Returns the number of bytes, which have been read by the stream.

Returns:
Number of bytes, which have been read so far.

available

public int available()
              throws IOException
Returns the number of bytes, which are currently available, without blocking.

Overrides:
available in class InputStream
Returns:
Number of bytes in the buffer.
Throws:
IOException - An I/O error occurs.

read

public int read()
         throws IOException
Returns the next byte in the stream.

Specified by:
read in class InputStream
Returns:
The next byte in the stream, as a non-negative integer, or -1 for EOF.
Throws:
IOException - An I/O error occurred.

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException
Reads bytes into the given buffer.

Overrides:
read in class InputStream
Parameters:
b - The destination buffer, where to write to.
off - Offset of the first byte in the buffer.
len - Maximum number of bytes to read.
Returns:
Number of bytes, which have been actually read, or -1 for EOF.
Throws:
IOException - An I/O error occurred.

close

public void close()
           throws IOException
Closes the input stream.

Specified by:
close in interface Closeable
Overrides:
close in class InputStream
Throws:
IOException - An I/O error occurred.

close

public void close(boolean pCloseUnderlying)
           throws IOException
Closes the input stream.

Parameters:
pCloseUnderlying - Whether to close the underlying stream (hard close)
Throws:
IOException - An I/O error occurred.

skip

public long skip(long bytes)
          throws IOException
Skips the given number of bytes.

Overrides:
skip in class InputStream
Parameters:
bytes - Number of bytes to skip.
Returns:
The number of bytes, which have actually been skipped.
Throws:
IOException - An I/O error occurred.

isClosed

public boolean isClosed()
Returns, whether the stream is closed.

Returns:
True, if the stream is closed, otherwise false.
