## [Java] Interface ModelMap<T>

- org.gradle.api.Named

- All Superinterfaces:
    ModelElement, Named

  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.

  Parameters:
    `` - the contract type for all items
