MapProperty

@ManagedType
@SupportsKotlinAssignmentOverloading
interface MapProperty<K, V> : Provider<Map<K, V>> , HasConfigurableValue, SupportsConvention(source)

Represents a property whose type is a Map of keys of type K and values of type V. Retains iteration order.

Instances of this interface are not thread-safe for reading and writing. It is not safe to share the same MapProperty instance between different projects.

Note: This interface is not intended for implementation by build script or plugin authors.

Since

5.1

Parameters

<K>

the type of keys.

<V>

the type of values.

Create an instance of this as a managed property (preferred).

Create an instance of this manually.
