ABSTRACT:
A network interface includes a network view portion developed using a low-level, high-performance programming language such as C++, and a user interface portion developed using a higher level scripted programming language such as Tcl/Tk. Variables in the C++ network view portion are linked to corresponding variables in the Tcl/Tk user interface portion. The network view and user interface portions are developed in accordance with a general framework, which in an illustrative embodiment includes: (1) a set of network structures stored in a database; (2) a C++ component including a network base class to generate functions common to multiple views, and a display class derived from the network base class to generate operations specific to a particular view; and (3) a Tcl/Tk component including a standard user interface corresponding to the network base class associated with a given view, and a special interface corresponding to the display class derived from that network base class. The network base classes support a range of viewing functions including identification, selection, zooming, panning, rotation, elision, collapse, expand, repositioning and transforming. The invention may be used to generate many different types of network views, including a hemisphere view based on a conformal warping of a two-dimensional network map onto a three-dimensional object, an arc map view, and a helix view illustrating network data hierarchies.
