Detailed Description

template<typename ImplementationType, ContextCapability... SupportedCapabilities>
class UE::Editor::DataStorage::Queries::TQueryContextImpl< ImplementationType, SupportedCapabilities >

Base used for context implementations. This will verify if a context is correctly implemented. Classes that implement capabilities should use this template to automatically satisfy the requirements of a query contract. Any missing functionality will be filled in by this template with a placeholder function that asserts. The supported capabilities are automatically extracted from the implementation type but can be overruled by providing a list of capabilities as extra template arguments. Note that any capabilities provided this way do need to be implemented by the implementation type.
