Weakness

CWE::Weakness represents a single CWE entry. Instances are constructed once when the embedded catalog is loaded and are then immutable.

Edge helpers

w.related_with("ChildOf")     # Array(Related)
w.parent_relations            # alias for related_with("ChildOf")
w.child_relations             # ParentOf edges (rare; use Catalog#children_of)
w.peer_relations              # PeerOf
w.can_precede_relations       # CanPrecede
w.can_follow_relations        # CanFollow

Convenience accessors

w.owasp_mappings  # TaxonomyMapping entries with taxonomy_name starting with "OWASP"
w.capec_ids       # alias for related_attack_patterns
w.deprecated?     # true if status is Deprecated or name starts with "DEPRECATED:"
w.summary         # "CWE-79: Improper Neutralization of Input ... (Base, Stable)"

Comparable, Equality, Hash

Weakness includes Comparable(Weakness) and is ordered by numeric id. Equality is by id, so cross-catalog instances with the same id compare equal and hash the same:

[CWE.find!(79), CWE.find!(20)].sort.first.id  # => 20
CWE.find!(79) == CWE.find!("CWE-79")          # => true

set = Set(CWE::Weakness).new
set << CWE.find!(79)
set << CWE.find!("CWE-79")
set.size # => 1
