The object model represented by the Progress.Json.ObjectModel package is based on the JavaScript concepts of objects and arrays. The programming model for the ABL JSON parser is to complete the parsing all at once to generate a tree of constructs. These constructs represent JSON objects and arrays.
The following figure shows the inheritance relationship between the parser classes:

Note: Objects of type JsonObject, JsonArray, and ObjectModelParser from the Progress.Json.ObjectModel package can be passed between an AppServer and an ABL client. For more information on passing objects between an AppServer and an ABL client, see OpenEdge Application Server: Developing AppServer Applications.
