Introduction

The LexEVS APIs fall into three primary categories:

• Core Services Includes - Core services include the LexBIGService, LexBIGServiceManager, CodedNodeSet and CodedNodeGraph classes, which provide the initial entry points for programmatic access to all system features and data.
• Service Extensions - The extension mechanism provides for pluggable system features. Current extension points allow for the introduction of custom load and indexing mechanisms; unique query, sort, and filter mechanisms; and generic functional extensions which can be advertised for availability to client programs.
• Utilities - Utility classes, such as those implementing iterator support, are provided by the system to provide convenience and optimize the handling of resources accessed through the runtime.

In the lower right section, there are two halves - the top half and the bottom half. The top half is used to apply restrictions. The bottom half provides query options and resolution.

If you select a Coded Node Graph in the lower left section of the LexEVS GUI, the lower right section will look like this:

Again, there are two halves to the lower right section. The top half allows restrictions to be applied to the selected Code Graph, and it works the same as it does for a Coded Node Set. Please see the section above on applying restrictions to a Coded Node Set.
