# Package org.eclipse.e4.core.di.suppliers

Application programming interfaces for dependency injection object suppliers.

## Package Specification

This package provides application programming interfaces for suppliers of objects that are searched by the dependency injection framework.

Injector takes the actual values to be injected from object suppliers. There are two types of object suppliers: primary and extended. A primary supplier has to be specified for each injection request. Extended suppliers apply to all injection requests.

Interface Summary
IObjectDescriptor: This interface describes objects created by the dependency injection.
IRequestor: Requestor represents an atomary operation performed during the injection.

Class Summary
ExtendedObjectSupplier: The base class for an "object supplier" - something that knows how to instantiate objects corresponding to the object descriptor.
PrimaryObjectSupplier: The base class for an "object supplier" - something that knows how to instantiate objects corresponding to the object descriptor.
