Macro Definition Documentation

DEFINE_FIELD

#define DEFINE_FIELD	(		name,
			storageObjectType,
			default_type,
			fieldPath,
			description )

Value:

 \
  template<typename VTYPE = default_type> \
  inline std::unique_ptr<IO::ReadDataWrapper<storageObjectType, VTYPE>> name() \
      const \
  { \
    return std::make_unique<IO::ReadDataWrapper<storageObjectType, VTYPE>>( \
        m_io, AQNWB::mergePaths(m_path, fieldPath)); \
  }

Defines a lazy-loaded field accessor function.

This macro generates a function that returns a lazy-loaded wrapper for a field.

Note

The Doxyfile.in defines a simplified expansion of this function for generating the documentation for the autogenerated function. This means: 1) When updating the macro here, we also need to ensure that the expansion in the Doxyfile.in is still accurate and 2) the docstring that is defined by the macro here is not being used by Doxygen but the version generated by its on PREDEFINED expansion.

Parameters

name	The name of the function to generate.
storageObjectType	The type of storage object (Attribute or Dataset).
default_type	The default type of the field.
fieldPath	The path to the field.
description	A detailed description of the field.

REGISTER_SUBCLASS

#define REGISTER_SUBCLASS	(		T,
			NAMESPACE )

Value:

  REGISTER_SUBCLASS_WITH_TYPENAME(T, NAMESPACE, #T)

Macro to register a subclass with the RegisteredType class registry.

This macro is a convenience wrapper around the main REGISTER_SUBCLASS macro, providing a default value for TYPENAME.

Parameters

T	The subclass type to register. The name must match the type in the schema.
NAMESPACE	The namespace of the subclass type in the format schema

REGISTER_SUBCLASS_IMPL

#define REGISTER_SUBCLASS_IMPL

(

T

)

Value:

bool T::registered_ = T::registerSubclass();

Macro to initialize the static member registered_ to trigger registration.

This macro ensures that the registration of the subclass occurs when the program starts.

Parameters

T	The subclass type to register.

REGISTER_SUBCLASS_WITH_TYPENAME

#define REGISTER_SUBCLASS_WITH_TYPENAME	(		T,
			NAMESPACE,
			TYPENAME )

Value:

  static bool registerSubclass() \
  { \
    AQNWB::NWB::RegisteredType::registerSubclass( \
        NAMESPACE "::" #T, \
        [](const std::string& path, std::shared_ptr<IO::BaseIO> io) \
            -> std::unique_ptr<AQNWB::NWB::RegisteredType> \
        { return std::make_unique<T>(path, io); }, \
        TYPENAME, \
        NAMESPACE); \
    return true; \
  } \
  static bool registered_; \
  virtual std::string getTypeName() const override \
  { \
    return TYPENAME; \
  } \
  virtual std::string getNamespace() const override \
  { \
    return NAMESPACE; \
  }

Macro to register a subclass with the RegisteredType class registry.

This macro defines:

• A static method registerSubclass that triggers registration of the subclass type when the subclass type is loaded.
• A static member registered_ that ensures the registration occurs.
• override getTypeName for the class to return the correct type name
• override getNamespace for the class to return the correct namespace used

Parameters

T	The subclass type to register. The name must match the type in the schema.
NAMESPACE	The namespace of the subclass type in the format schema
TYPENAME	The name of the type (usually the class name).
