Module age_names 

Apache AGE graph and label name validation.

AGE validates names with anchored regular expressions built from the Unicode ID_Start and ID_Continue classes (name_validation.c):

• graph names: ^[ID_Start_][ID_Continue.-]*[ID_Continue]$, 3 to 63 bytes
• label names: ^[ID_Start_][ID_Continue]*$, 1 to 63 bytes

Lengths are byte lengths because AGE measures them with strlen.

Constants

EDGE_DEFAULT_LABEL_NAME

Name of the AGE default edge label that every graph owns.

MAX_GRAPH_NAME_LEN

AGE MAX_GRAPH_NAME_LEN.

MAX_LABEL_NAME_LEN

AGE MAX_LABEL_NAME_LEN (NAMEDATALEN - 1).

MIN_GRAPH_NAME_LEN

AGE MIN_GRAPH_NAME_LEN.

MIN_LABEL_NAME_LEN

AGE MIN_LABEL_NAME_LEN.

VERTEX_DEFAULT_LABEL_NAME

Name of the AGE default vertex label that every graph owns.

Functions

is_valid_graph_name

AGE is_valid_graph_name: 3 to 63 bytes, an ID_Start character or underscore first, ID_Continue characters plus . and - in the middle, and an ID_Continue character last.

is_valid_label_name

AGE is_valid_label_name: 1 to 63 bytes, an ID_Start character or underscore first, and ID_Continue characters after it.
