Model Providers

Identifier:
org.eclipse.core.resources.modelProviders

Since:
3.2

Description:
A model provider serves two purposes. Firstly, it is a means of grouping the resource mappings of a single model together for the purposes of performing operations, display, etc. Also, it provides a means of mapping a set of file system resources to the resource mappings that describe how a model maps to resources.
