  • Method Details

    • empty

      SetProperty<T> empty()
      Sets the value of this property to an empty collection, and replaces any existing value.
      Specified by:
      empty in interface HasMultipleValues<T>
      Returns:
      this property.

    • value

      SetProperty<T> value(@Nullable Iterable<? extends T> elements)
      Sets the value of the property to the elements of the given iterable, and replaces any existing value. This property will query the elements of the iterable each time the value of this property is queried.

      This is the same as HasMultipleValues.set(Iterable) but returns this property to allow method chaining.

      Specified by:
      value in interface HasMultipleValues<T>
      Parameters:
      elements - The elements, can be null.
      Returns:
      this

    • value

      SetProperty<T> value(Provider<? extends Iterable<? extends T>> provider)
      Sets the property to have the same value of the given provider, and replaces any existing value. This property will track the value of the provider and query its value each time the value of this property is queried. When the provider has no value, this property will also have no value.

      This is the same as HasMultipleValues.set(Provider) but returns this property to allow method chaining.

      Specified by:
      value in interface HasMultipleValues<T>
      Parameters:
      provider - Provider of the elements.
      Returns:
      this

    • convention

      SetProperty<T> convention(@Nullable Iterable<? extends T> elements)
      Specifies the value to use as the convention for this property. The convention is used when no value has been set for this property.
      Specified by:
      convention in interface HasMultipleValues<T>
      Parameters:
      elements - The elements, or null when the convention is that the property has no value.
      Returns:
      this

    • convention

      SetProperty<T> convention(Provider<? extends Iterable<? extends T>> provider)
      Specifies the provider of the value to use as the convention for this property. The convention is used when no value has been set for this property.
      Specified by:
      convention in interface HasMultipleValues<T>
      Parameters:
      provider - The provider of the elements
      Returns:
      this

    • unset

      SetProperty<T> unset()
      Unsets this object's explicit value, allowing the convention to be selected when evaluating this object's value.

      This is similar to calling value(Iterable) with a null argument.

      Specified by:
      unset in interface SupportsConvention

    • unsetConvention

      SetProperty<T> unsetConvention()
      Unsets this object's convention value.

      This is similar to calling convention(Iterable) with a null argument.

      Specified by:
      unsetConvention in interface SupportsConvention
