buf

The buffer.

count

The number of characters to use in the buffer.

pos

The position in the buffer.

InputStreamBuffer(byte[])

Creates an InputStreamBuffer, given an array of bytes.

InputStreamBuffer(byte[], int)

Creates an InputStreamBuffer, given an array of bytes.

available()

Returns the number of available bytes in the buffer.

read()

Reads a byte.

read(byte[], int, int)

Reads into an array of bytes.

reset()

Resets the buffer to the beginning.

skip(int)

Skips bytes of input.

  protected byte buf[]

The buffer.

  protected int pos

The position in the buffer.

  protected int count

The number of characters to use in the buffer.

  public InputStreamBuffer(byte buf[])

Creates an InputStreamBuffer, given an array of bytes.

Parameters:

buf - the input buffer (not copied)

InputStreamBuffer

  public InputStreamBuffer(byte buf[],
                           int length)

Creates an InputStreamBuffer, given an array of bytes.

Parameters:

buf - the input buffer (not copied)

length - the number of bytes in the buffer

  public synchronized int read()

Reads a byte.

Returns:

the byte read, or -1 if the end of the stream is reached.

Overrides:

read in class InputStream

read

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

Reads into an array of bytes. For efficiency, this method should be overridden in a subclass (the default implementation reads 1 byte at a time).

Parameters:

b - the buffer into which the data is read

off - the start offset of the data

len - the maximum number of bytes read

Returns:

the actual number of bytes read; -1 is returned when the end of the stream is reached.

Overrides:

read in class InputStream

skip

  public synchronized int skip(int n)

Skips bytes of input.

Parameters:

n - bytes to be skipped

Returns:

actual number of bytes skipped

Overrides:

skip in class InputStream

available

  public synchronized int available()

Returns the number of available bytes in the buffer.

Returns:

the number of available bytes

Overrides:

available in class InputStream

reset

  public synchronized void reset()

Resets the buffer to the beginning.

Overrides:

reset in class InputStream
