Feature Table Methods

The following methods allow creation and editing of named Feature Table objects.

SIS uses named Feature Table objects as a fast and efficient way of controlling the display, e.g. Brush, Pen, Symbol, of items. Named Feature Table objects consist of a hierarchy of Feature Codes, each of which has styling information which graphical items with the Feature Code will use when they are drawn. The Feature Codes hierarchy allows features of a similar type, e.g. Motorways, A-Roads, B-Roads, to be grouped together for fast switching on and off.

See SIS_OT_FTABLE for further details.
