ICompositeRepository (Eclipse Platform API Specification)

Type Parameters:

T - The type of repository content. Typically this is either IInstallableUnit or IArtifactKey.

All Superinterfaces:

IAdaptable, IQueryable<T>, IRepository<T>
```
public interface ICompositeRepository<T>
extends IRepository<T>
```
A composite repository doesn't directly contain any contents, but rather contains only a list of child repositories. The composite repository aggregates content from the children and acts as a single repository containing the union of all child contents. When a composite repository is queried programmatically, it will appear to contain all elements that currently exist in one or more of its children.

Since:

2.0
