getting

abstract fun getting(key: K): Provider<V>(source)

Returns a provider that resolves to the value of the mapping of the given key. It will have no value if the property has no value, or if it does not contain a mapping for the key.

The returned provider will track the value of this property and query its value when it is queried.

This method is equivalent to


    map(m -> m.get(key))
but possibly more efficient.

Return

a Provider for the value
