Example in JsonQL.Demos Project

Classes in namespace JsonQL.Demos.CustomJsonQL.Compilation demonstrate how to add new functions, operators, and Json path functions.

Note

Custom functions, custom literals (e.g., JsonQLReleaseDate), operators, path functions used in examples in JsonQL.Demos use meaningless names to avoid potential conflicts with adding similar functions, operators and path functions in JsonQL in the future.

The sections that follow provide descriptions of implemented custom functions, literal, etc, and then a summary example is provided in section Summary Examples.
