Overview

How we track the Assess properties attached to objects

Finalized objects should run through this class as the Finalizers have tightly coupled dependencies on each other.

.copy(source, target) ⇒ Object

Copy the properties from one object to the next, assuming the target does not already have its own properties.

Parameters:

Parameters:

  • source (Object) —

    the thing to duplicate

Returns:

  • (Object) —

    the duplicate of the original, or the original if it does not respond to duplication
