class Hashable
Defined at line 19 of file ../../src/ui/lib/escher/util/hashable.h
A simple base class for self-hashing objects. Copying and moving is allowed;
it's up to subclasses to disallow, if they want.
Not thread-safe.

bool operator== (const Hashable & other)Defined at line 35 of file ../../src/ui/lib/escher/util/hashable.h
bool operator!= (const Hashable & other)Defined at line 36 of file ../../src/ui/lib/escher/util/hashable.h
Protected Methods
void InvalidateHash ()Subclasses must call whenever the object's state changes such that
GenerateHash() would return a different result.

bool HasCachedHash ()Returns true if there is a cached hash value, i.e. if there has been no
call to InvalidateHash() since the last call of GenerateHash(). Mostly for
testing.
