A method and apparatus for proving hover help support is described. In one embodiment, the method includes loading a documentation file generated from application source code. The method may also include parsing the documentation file to determine a context of elements within the documentation file. Furthermore, the method may include generating a model of the documentation file based on the context of the elements and storing the model in a memory.

Hover help support for application source code

A metadata repository for use in an integrated development environment is provided. The metadata repository is layered to define levels of common behaviour useful to different types of application development tools. The most general use tools have access to metadata at the level of simple constructed types; more specialised tools have access to components that contain properties of a target language; highly specialised tools have access to composed partitionable part metadata that can be used for constructing distributed applications.

Hierarchical metadata store for an integrated development environment

When data, such as tool data, is commonly accessible, there is a danger that concurrent user processes will make overlapping modifications and leave the data in an incomplete or incomprehensible state. The invention provides a locking mechanism to guard against this. The lock objects are maintained in pool or repository. Two types of lock objects are provided; shareable locks that may be shared by many user processes and permit only read access to the locked data, and exclusive locks, useable by only one user process at a time, that permit the owning process to modify the locked data.
