Method Detail

read

public int read()
         throws IOException

Description copied from class: FilterInputStream

Reads a single byte from this FilterInputStream and returns the result as an int. The low-order byte is returned or -1 of the end of stream was encountered. This implementation returns a byte from the target stream.

Overrides:

read in class FilterInputStream

Returns:

the byte read or -1 if end of stream.

Throws:

IOException - If the stream is already closed or another IOException occurs.

read

public int read(byte[] buf,
                int off,
                int nbytes)
         throws IOException

Description copied from class: FilterInputStream

Reads at most count bytes from this FilterInputStream and stores them in byte array buffer starting at offset. Answer the number of bytes actually read or -1 if no bytes were read and end of stream was encountered. This implementation reads bytes from the target stream.

Overrides:

read in class FilterInputStream

Parameters:

buf - the byte array in which to store the read bytes.

off - the offset in buffer to store the read bytes.

nbytes - the maximum number of bytes to store in buffer.

Returns:

the number of bytes actually read or -1 if end of stream.

Throws:

IOException - If the stream is already closed or another IOException occurs.

skip

public long skip(long nbytes)
          throws IOException

Description copied from class: FilterInputStream

Skips count number of bytes in this InputStream. Subsequent read()'s will not return these bytes unless reset() is used. This implementation skips count number of bytes in the target stream.

Overrides:

skip in class FilterInputStream

Parameters:

nbytes - the number of bytes to skip.

Returns:

the number of bytes actually skipped.

Throws:

IOException - If the stream is already closed or another IOException occurs.
