1187552 - Support direct ownership of C++ objects by Java objects

Status: RESOLVED FIXED

(Firefox for Android Graveyard :: General, defect)

Description

[(inactive) Jim Chen [:jchen] [:darchons]]

The initial work done in bug 1186530 includes a WeakPtr ownership model, where the Java object owns a WeakPtr to the actual C++ object. This bug will add a support for a direct ownership model where the Java object owns the C++ object itself.

Attachment: Support direct ownership of C++ objects by Java objects (v1)

Add a direct ownership model where the Java object owns the
corresponding C++ object directly, in addition to the WeakPtr model
where the Java object owns a WeakPtr to the C++ object. The WeakPtr
model is chosen when the implementing C++ class inherits from
SupportsWeakPtr. Otherwise, the direct ownership model is chosen. Under
the direct ownership model, a UniquePtr object must be used to attach
the containing C++ object to a Java object, to ensure ownership is
passed on to the Java object.

Attachment: Make NativeJSContainer use direct ownership model (v1)

Make NativeJSContainer/NativeJSObject Java objects own their
corresponding C++ objects directly, to reduce an extra
allocation/deallocation for each object and to simplify code.
