The Guildhall APIs

The diagram above depicts Guildhall's architecture. All references to the host system are confined to the Host Abstraction Layer. Above that layer only Guildhall APIs are used. On Mac nearly everything in the HAL references Core functionality via C++. A few things, such as cursor control and the basic interface to the event system, are handled at the NSApplication level using objective C. You can click on any of the sections to get more information, or you can use the alphabetized list in the sidebar. Most of the subsections mention the classes defined therein.
