NamingConvention Objects

class NamingConvention(ABC)

[view_source]

Initializes naming convention to generate identifier with max_length if specified. Base naming convention is case sensitive by default

PATH_SEPARATOR

Subsequent nested fields will be separated with the string below, applies both to field and table names

is_case_sensitive

@property
@abstractmethod
def is_case_sensitive() -> bool

[view_source]

Tells if given naming convention is producing case insensitive or case sensitive identifiers.

normalize_identifier

@abstractmethod
def normalize_identifier(identifier: str) -> str

[view_source]

Normalizes and shortens the identifier according to naming convention in this function code

normalize_table_identifier

def normalize_table_identifier(identifier: str) -> str

[view_source]

Normalizes and shortens identifier that will function as a dataset, table or schema name, defaults to normalize_identifier

make_path

def make_path(*identifiers: str) -> str

[view_source]

Builds path out of identifiers. Identifiers are neither normalized nor shortened

break_path

def break_path(path: str) -> Sequence[str]

[view_source]

Breaks path into sequence of identifiers

normalize_path

def normalize_path(path: str) -> str

[view_source]

Breaks path into identifiers, normalizes components, reconstitutes and shortens the path

normalize_tables_path

def normalize_tables_path(path: str) -> str

[view_source]

Breaks path of table identifiers, normalizes components, reconstitutes and shortens the path

shorten_fragments

def shorten_fragments(*normalized_idents: str) -> str

[view_source]

Reconstitutes and shortens the path of normalized identifiers

name

@classmethod
def name(cls) -> str

[view_source]

Naming convention name is the name of the module in which NamingConvention is defined

shorten_identifier

@staticmethod
@lru_cache(maxsize=None)
def shorten_identifier(normalized_ident: str,
                       identifier: str,
                       max_length: int,
                       collision_prob: float = _DEFAULT_COLLISION_PROB) -> str

[view_source]

Shortens the name to max_length and adds a tag to it to make it unique. Tag may be placed in the middle or at the end
