chunk of data from a stream into the internal filter's buffer. The
methods reads buffSize bytes from
the current position in the stream. No need to use this method if you
use SFRecord's binding capabilities - it will be called internally as
variable = object.Read(stream)
stream - A stream to read - SFStream or an object that
supports IStream interface.
returned value: Boolean success indicator
The returned value will be True only if the entire buffer is filled
from the stream. If the end of the stream is reached before that -
False will be returned.
SFFilter can read/write data in chunks equal to its current buffer
size (in bytes). Actual value access is done later by using the PutVar/GetVar
or Put/Get methods over the internal buffer. This allows the library
internally to optimize the access to the stream and the application to
do so on its own if low level access is desired.
