|
void |
addAll(Provider<? extends java.lang.Iterable<? extends T>> provider) |
Adds zero or more elements to the property value.
|
void |
addAll(T... elements) |

|
HasMultipleValues<T> |
empty() |
Sets the value of this property to an empty collection, and replaces any existing value.
|
void |
finalizeValue() |
Disallows further changes to the value of this property.
|
void |
set(java.lang.Iterable<? extends T> elements) |
Sets the value of the property to the elements of the given iterable, and replaces any existing value.
|
void |
set(Provider<? extends java.lang.Iterable<? extends T>> provider) |

This method can also be used to clear the value of the property, by passing null
as the value.

The given provider will be queried when the value of this property is queried. This property will have no value when the given provider has no value.

elements
- The elements to addvoid addAll(java.lang.Iterable<? extends T> elements)
The given iterable will be queried when the value of this property is queried.
elements
- The elements to add.void addAll(Provider<? extends java.lang.Iterable<? extends T>> provider)
The given provider will be queried when the value of this property is queried. This property will have no value when the given provider has no value.
provider
- Provider of elementsvoid finalizeValue()

will fail.
When this property has elements provided by a Provider
, the value of the provider is queried when this method is called and the value of the provider will no longer be tracked.
Note that although the value of the property will not change, the resulting collection may contain mutable objects. Calling this method does not guarantee that the value will become immutable.
