Cooper Base Library (cooper.jar)

The Cooper Base Library (contained in cooper.jar) is a small library that can be optionally used in Elements projects for the Java and Android platform. It provides some of the core types, classes and functions that are needed for more advanced language features of Oxygene, C# and Swift, such as Future Types, Await support, advanced delegate support, LINQ, and more.

Source Code

The Cooper Base Library is open source and implemented fully in Oxygene. You can find the source code on GitHub, and contributions and pull requests are more than welcome.

Note that you will usually need the very latest compiler to rebuild cooper.jar yourself, and in some cases, the git repository might even contain code that requires a later compiler than is available. Refer to the commit messages for details on this, and check out an older revision, if necessary.


The Cooper Base Library is divided into these namespaces:

Version Notes

cooper.jar was called com.remobjects.elements.rtl.jar in Elements 8.2 and below. Projects will automatically be migrated to use the cooper.jar reference when opened in Fire, Water or Visual Studio.
