Enclosing class:

Bitstream<T>

public static interface Bitstream.ByteStream<T>

General byte stream.

Method Summary

Methods

Modifier and Type	Method and Description
boolean	canInput() Return true if stream can handle input, i.e.
boolean	canOutput() Return true if stream can handle output, i.e.
void	close() Closing the underlying stream, implies flush().
void	flush() Synchronizes all underlying output stream operations, or do nothing.
T	getStream() Returns the underlying stream
void	mark(int readLimit) Set markpos to current position, allowing the stream to be reset().
long	position() Returns the byte position in the stream.
int	read() Reads one byte from the stream.
void	reset() Reset stream position to markpos as set via mark(int).
void	setStream(T stream) Sets the underlying stream, without close()ing the previous one.
long	skip(long n) It is implementation dependent, whether backward skip giving a negative number is supported or not.
int	write(byte val) Writes one byte, to the stream.

Method Detail

setStream

void setStream(T stream)

Sets the underlying stream, without close()ing the previous one.

getStream

T getStream()

Returns the underlying stream

close

void close()
           throws IOException

Closing the underlying stream, implies flush().

Implementation will null the stream references, hence setStream(Object) must be called before re-using instance.

Throws:

IOException

flush

void flush()
           throws IOException

Synchronizes all underlying output stream operations, or do nothing.

Throws:

IOException

canInput

boolean canInput()

Return true if stream can handle input, i.e. read().

canOutput

boolean canOutput()

Return true if stream can handle output, i.e. write(byte)

position

long position()

Returns the byte position in the stream.

skip

long skip(long n)
          throws IOException

It is implementation dependent, whether backward skip giving a negative number is supported or not.

Parameters:

n - number of bytes to skip

Returns:

actual skipped bytes

Throws:

IOException

mark

void mark(int readLimit)
          throws UnsupportedOperationException

Set markpos to current position, allowing the stream to be reset().

Parameters:

readLimit -

Throws:

UnsupportedOperationException - is not supported, i.e. if stream is not an input stream.

reset

void reset()
           throws UnsupportedOperationException,
                  IllegalStateException,
                  IOException

Reset stream position to markpos as set via mark(int).

markpos is kept, hence reset() can be called multiple times.

Throws:

UnsupportedOperationException - is not supported, i.e. if stream is not an input stream.

IllegalStateException - if markpos has not been set via mark(int) or reset operation failed.

IOException - if reset operation failed.

read

int read()
         throws UnsupportedOperationException,
                IOException

Reads one byte from the stream.

Returns Bitstream.EOS is end-of-stream is reached, otherwise the resulting value.

Throws:

IOException

UnsupportedOperationException - is not supported, i.e. if stream is not an input stream.

write

int write(byte val)
          throws UnsupportedOperationException,
                 IOException

Writes one byte, to the stream.

Returns Bitstream.EOS is end-of-stream is reached, otherwise the written value.

Throws:

IOException

UnsupportedOperationException - is not supported, i.e. if stream is not an output stream.
