class Reffable
Defined at line 27 of file ../../src/ui/lib/escher/base/reffable.h
Reffable is a threadsafe ref-counted base class that is suitable for use with fxl::RefPtr.
It provides a virtual OnZeroRefCount() method that subclasses can override to avoid immediate
destruction when their ref-count becomes zero.
Use this class similarly to fxl::RefCountedThreadSafe. For example, instead
of:
class Foo : public RefCountedThreadSafe
<Foo
> { ...
simply say:
class Foo : public Reffable { ...

return false are responsible for ensuring that the object is eventually
destroyed.
