Interface IRequiredCapability

All Superinterfaces:

IRequirement

All Known Implementing Classes:

RequiredCapability

public interface IRequiredCapability
extends IRequirement

A required capability represents some external constraint on an IInstallableUnit. Each capability represents something an IInstallableUnit needs that it expects to be provided by another IInstallableUnit. Capabilities are entirely generic, and are intended to be capable of representing anything that an IInstallableUnit may need either at install time, or at runtime.

Capabilities are segmented into namespaces. Anyone can introduce new capability namespaces. Some well-known namespaces are introduced directly by the provisioning framework.
