Package org.gradle.model

# Interface ModelMap<T>

Type Parameters:
  `T` - the contract type for all items

All Superinterfaces:
  `Iterable<T>`, `ModelElement`, `Named`

All Known Subinterfaces:
  `BinaryContainer`, `ComponentSpecContainer`, `FunctionalSourceSet`, `TestSuiteContainer`

@Incubating public interface ModelMap<T> extends Iterable<T>, ModelElement
Model backed map like structure allowing adding of items where instantiation is managed.

`Managed` types may declare model map properties. Model maps can only contain managed types.
