class hdmf.build.classgenerator.ClassGeneratorManager

Bases: object

property custom_generators

register_generator(generator)

Add a custom class generator to this ClassGeneratorManager.

Generators added later are run first. Duplicates are moved to the top of the list.

Parameters:

generator (type) – the CustomClassGenerator class to register

generate_class(data_type, spec, parent_cls, attr_names, type_map, post_init_method=None)

Get the container class from data type specification. If no class has been associated with the data_type from namespace, a class will be dynamically created and returned.

Parameters:

• data_type (str) – the data type to create a AbstractContainer class for

• spec (BaseStorageSpec) – The spec for the class to be generated.

• parent_cls (type) – Parent class used for docval ancestor args.

• attr_names (dict) – The names of the attributes from the spec.

• type_map (TypeMap)

• post_init_method (Callable) – The function used as a post_init method to validate the class generation.

Returns:

the class for the given namespace and data_type

Return type:

type

exception hdmf.build.classgenerator.TypeDoesNotExistError

Bases: Exception

class hdmf.build.classgenerator.CustomClassGenerator(*args, **kwargs)

Bases: object

Subclass this class and register an instance to alter how classes are auto-generated.

classmethod apply_generator_to_field(field_spec, bases, type_map)

Return True to signal that this generator should return on all fields not yet processed.

classmethod process_field_spec(classdict, docval_args, parent_cls, attr_name, not_inherited_fields, type_map, spec)

Add __fields__ to the classdict and update the docval args for the field spec with the given attribute name. :param classdict: The dict to update with __fields__ (or a different parent_cls._fieldsname). :param docval_args: The list of docval arguments. :param parent_cls: The parent class. :param attr_name: The attribute name of the field spec for the container class to generate. :param not_inherited_fields: Dictionary of fields not inherited from the parent class. :param type_map: The type map to use. :param spec: The spec for the container class to generate.

classmethod post_process(classdict, bases, docval_args, spec)

Convert classdict[‘__fields__’] to tuple and update docval args for a fixed name and default name. :param classdict: The class dictionary to convert with ‘__fields__’ key (or a different bases[0]._fieldsname) :param bases: The list of base classes. :param docval_args: The dict of docval arguments. :param spec: The spec for the container class to generate.

classmethod set_init(classdict, bases, docval_args, not_inherited_fields, name)

class hdmf.build.classgenerator.MCIClassGenerator(*args, **kwargs)

Bases: CustomClassGenerator

classmethod apply_generator_to_field(field_spec, bases, type_map)

Return True if the field spec has quantity * or +, False otherwise.

classmethod process_field_spec(classdict, docval_args, parent_cls, attr_name, not_inherited_fields, type_map, spec)

Add __clsconf__ to the classdict and update the docval args for the field spec with the given attribute name. :param classdict: The dict to update with __clsconf__. :param docval_args: The list of docval arguments. :param parent_cls: The parent class. :param attr_name: The attribute name of the field spec for the container class to generate. :param not_inherited_fields: Dictionary of fields not inherited from the parent class. :param type_map: The type map to use. :param spec: The spec for the container class to generate.

classmethod post_process(classdict, bases, docval_args, spec)

Add MultiContainerInterface to the list of base classes. :param classdict: The class dictionary. :param bases: The list of base classes. :param docval_args: The dict of docval arguments. :param spec: The spec for the container class to generate.

classmethod set_init(classdict, bases, docval_args, not_inherited_fields, name)
