class Owner

Defined at line 19 of file ../../src/ui/lib/escher/base/owner.h

Subclasses of Owner manage the lifecycle of Ownable objects. When the

ref-count of an Ownable reaches zero, Owner::ReceiveOwnable() is invoked;

the Owner is then responsible for deciding whether to destroy it, recycle it,

etc. The Owner may only own Ownables that are parameterized with the same

TypeInfoT type.
