Public Member Functions

 Serializable (Context *context)
 Construct.
 
 ~Serializable () override
 Destruct.
 
virtual void OnSetAttribute (const AttributeInfo &attr, const Variant &src)
 Handle attribute write access. Default implementation writes to the variable at offset, or invokes the set accessor.
 
virtual void OnGetAttribute (const AttributeInfo &attr, Variant &dest) const
 Handle attribute read access. Default implementation reads the variable at offset, or invokes the get accessor.
 
virtual const Vector< AttributeInfo > * GetAttributes () const
 Return attribute descriptions, or null if none defined.
 
virtual const Vector< AttributeInfo > * GetNetworkAttributes () const
 Return network replication attribute descriptions, or null if none defined.
 
virtual bool Load (Deserializer &source)
