NAME

display_feature - abstract class for visualization networks

DESCRIPTION

Display_feature is an abstract class that provides instance variables and methods for manipulating visualization filters. It's primary purpose is to delegate unrecognizable messages to it's data_out. This may cause execution of the network in some cases (i.e., the network is automatically updated).

SUPERCLASS

generic_data_filter

INSTANCE VARIABLES

none

MESSAGES

does_not_understand an internal method to forward all unrecognized messages to its data_out. Will automatically create the data_out and execute the network as required.

create_data_out! creates a display_data output object and sets the data_out instance variable (inherited from generic_data_filter).

EXAMPLE

See particular examples such as warp_vector or delaunay.
