int com.quadcap.io.DotStuffInputStream.read (  byte  b[], int  off, int  len )  throws IOException

Reads up to len bytes of data from this input stream into an array of bytes. This method blocks until some input is available. 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 total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached. Exceptions: IOException  if an I/O error occurs. Definition at line 149 of file DotStuffInputStream.java.

int com.quadcap.io.DotStuffInputStream.read (   )  throws IOException

Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. 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. The read method of DotStuffInputStream returns -1 when the characteristic 'single dot on a line by itself' end signature, and removes all leading dots otherwise. Returns: the next byte of data, or -1 if the end of the stream is reached. Exceptions: IOException  if an I/O error occurs. Definition at line 90 of file DotStuffInputStream.java.

Referenced by com.quadcap.io.Test.testDot().

long com.quadcap.io.DotStuffInputStream.skip (  long  n  )  throws IOException

Skips over and discards n bytes of data from the input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned. Parameters: n  the number of bytes to be skipped. Returns: the actual number of bytes skipped. Exceptions: IOException  if an I/O error occurs.
