Detailed Description

Underlying structure for the PositionStream object.

PositionStreams are used for accessing Attributes. Each one represents a stream of corpus positions, representing positions where a given item occurs.

Field Documentation

Attribute* attribute

The Attribute on which this PositionStream has been opened.
