public interface ByteInput
extends Closeable

An input stream of bytes.

Method Summary

int	available() Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.
int	read() Reads the next byte of data from the input stream.
int	read(byte[] b) Read some bytes from the input stream into the given array.
int	read(byte[] b, int off, int len) Read some bytes from the input stream into the given array.
long	skip(long n) Skips over and discards up to n bytes of data from this input stream.

Method Detail

read

int read()
         throws IOException

Reads the next byte of data from the input stream. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Returns:

the next byte, or -1 if the end of stream has been reached

Throws:

IOException - if an error occurs

read

int read(byte[] b)
         throws IOException

Read some bytes from the input stream into the given array. Returns the number of bytes actually read (possibly zero), or -1 if the end of stream has been reached.

Parameters:

b - the destination array

Returns:

the number of bytes read (possibly zero), or -1 if the end of stream has been reached

Throws:

IOException - if an error occurs

read

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

Read some bytes from the input stream into the given array. Returns the number of bytes actually read (possibly zero), or -1 if the end of stream has been reached.

Parameters:

b - the destination array

off - the offset into the array into which data should be read

len - the number of bytes to attempt to fill in the destination array

Returns:

the number of bytes read (possibly zero), or -1 if the end of stream has been reached

Throws:

IOException - if an error occurs

available

int available()
              throws IOException

Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.

Returns:

the number of bytes

Throws:

IOException - if an error occurs

skip

long skip(long n)
          throws IOException

Skips over and discards up to n bytes of data from this input stream.

Parameters:

n - the number of bytes to attempt to skip

Returns:

the number of bytes skipped

Throws:

IOException - if an error occurs
