deferred class EIFFEL_NODE
Summary
top
Provides two basic operations: display for debug purposes, and generate for more generic node handling.
Any other operation should be provided by an external VISITOR.
See also: EIFFEL_NON_TERMINAL_NODE, EIFFEL_LIST_NODE, EIFFEL_TERMINAL_NODE, EIFFEL_IMAGE
Direct parents
Inherit list: VISITABLE
Insert list: EIFFEL_NODE_HANDLER
Known children
Inherit list: EIFFEL_LIST_NODE, EIFFEL_NON_TERMINAL_NODE, EIFFEL_TERMINAL_NODE
