In many ways, EGL is like other programming languages. It includes familiar constructs such as loops and transfers of control. It is built on a set of types, each of which defines the operations and values that are available for each “instance” of the type. Last, it involves a process for validating source code and for converting the source code into a less abstract form, closer to the runtime need.
EGL is unusual in its reliance on stereotypes, which are declarations used by the software that converts the source code to another form such as Java or JavaScript. These declarations add simplicity. They let you write similar code even as you code for different runtime systems.
Other topics clarify what a stereotype is, starting with a review of the process for converting source code. Also included is an overview of the EGL types.
