Void	set(V value, MetaParam.Writable... metas) Set this value along with optional metadata parameters.

Method Detail

set

Void set(V value,
         MetaParam.Writable... metas)

Set this value along with optional metadata parameters. DESIGN RATIONALE:

• It returns 'Void' instead of 'void' in order to avoid the need to add overloaded methods in functional map that take Consumer instead of Function. This is what of those annoying side effects of the java language, which didn't make `void` an Object.

remove

Void remove()

Removes the value and any metadata parameters associated with it. DESIGN RATIONALE:

• It returns 'Void' instead of 'void' in order to avoid the need to add overloaded methods in functional map that take Consumer instead of Function. This is what of those annoying side effects of the java language, which didn't make `void` an Object.
• Why not have a single `set(Optional...)` operation that takes Optional.empty() instead of having a set(Object, MetaParam.Writable[]) and remove()? The two-method approach feels cleaner and less cumbersome than having to always pass in Optional to set().
