Member Function Documentation

virtual void jcpp::BufferedReader::close

(

)

[inline, virtual]

Close the underlying file descriptor.

Implements jcpp::Reader.

                       {
    in->close();
  }

virtual void jcpp::BufferedReader::mark

(

)

[inline, virtual]

Mark this point in the read stream.

Reimplemented from jcpp::Reader.

                      {
    en((char *)"not allowed to use mark() in Reader");
  }

virtual boolean jcpp::BufferedReader::markSupported

(

)

[inline, virtual]

Determine if this stream supports marking the stream.

Reimplemented from jcpp::Reader.

                                  {
    return FALSE;
  }

virtual int jcpp::BufferedReader::read

(

)

[virtual]

Read a single character off the stream.

Implements jcpp::Reader.

virtual int jcpp::BufferedReader::read	(	char *	cbuf,
		int	length
	)		[inline, virtual]

Read length bytes into the buffer pointed to by cbuf.

Reimplemented from jcpp::Reader.

                                           {
    return read(cbuf, 0 , length);
  }

int jcpp::BufferedReader::preRead	(	char *	cbuf,
		int	off,
		int	length
	)		[private]

This reads a blob of characters, but does not necessarily fulfill the request. A negative return value means an error has occurred.

virtual int jcpp::BufferedReader::read	(	char *	cbuf,
		int	off,
		int	length
	)		[virtual]

Read <em length /em> bytes into the buffer pointed to by <em cbuf /em> beginning at the offset <em off /em>.

Implements jcpp::Reader.

virtual boolean jcpp::BufferedReader::ready

(

)

[inline, virtual]

Answers TRUE if the stream is ready to be read.

Implements jcpp::Reader.

                          {
    return (nextChar < nChars) || in->ready();
  }

virtual void jcpp::BufferedReader::reset

(

)

[inline, virtual]

Reset the stream back to the previously set mark, if supported, error otherwise.

Reimplemented from jcpp::Reader.

                       {
    en((char *)":-( Reader::reset() not supported");
  }

virtual long jcpp::BufferedReader::skip

(

long

length

)

[virtual]

Skip length bytes or to end-of-file whichever comes first.

Implements jcpp::Reader.

virtual CFREE char* jcpp::BufferedReader::readLine

(

)

[virtual]

Read a line, the terminating newline is replaced with a null.

int jcpp::BufferedReader::findLineInBuffer

(

)

[private]

See if a newline char appears in the current buffer, if so return the index pointing to the newline, otherwise retrun -1.

void jcpp::BufferedReader::fill

(

)

[private]

Fill the buffer; note that this may block.

void jcpp::BufferedReader::en

(

char *

str

)

[inline, protected]

Generic error stream.

Reimplemented from jcpp::Reader.

                     {
    ::fprintf(stderr, "%s\n", str);
  }
