Purge uses ConstantsTrait

Defines the possible purge directions for graph edges in ArangoDB.

These constants indicate which documents should be automatically removed when an edge vertex is deleted:

OUTBOUND : Purge the target (to) documents when the source (from) vertex is removed.
INBOUND : Purge the source (from) documents when the target (to) vertex is removed.
BOTH : Purge both from and to documents when either vertex is removed.

These values are intended for use with edge traversal rules in graph queries and edge deletion callbacks.
