CWE module

The CWE module is the convenience surface — every method here delegates to CWE::Catalog.default. For a longer-lived catalog reference, capture CWE.catalog once.

Id parsing

Method	Returns	Notes
`CWE.parse_id?(s : String)`	`Int32?`	nil on bad input
`CWE.parse_id(s : String)`	`Int32`	raises `CWE::ParseError`

Recognized forms: "CWE-79", "cwe-79", "CWE_79", "CWE:79", "79", "0079". Leading/trailing whitespace is stripped.

Lookups

Method	Returns
`CWE.find(id)`	`Weakness?`
`CWE.find!(id)`	`Weakness` (raises `NotFoundError`)
`CWE[id]`	`Weakness` (raises `NotFoundError`)
`CWE[id]?`	`Weakness?`
`CWE.includes?(id)`	`Bool`
`CWE.all`	`Array(Weakness)`
`CWE.each { \|w\| ... }`	iterates
`CWE.size`	`Int32` (weakness count)
`CWE.entry(id)`	`Weakness \| Category \| View \| Nil`

Search & filters

Method	Returns
`CWE.search(q : String)`	`Array(Weakness)`
`CWE.search_by_name(q : String)`	`Array(Weakness)`
`CWE.with_abstraction(level : Abstraction)`	`Array(Weakness)`
`CWE.with_status(status : Status)`	`Array(Weakness)`

Relationships

All accept an optional view_id: filter.

Method	Returns
`CWE.parents_of(id, view_id: nil)`	`Array(Weakness)`
`CWE.children_of(id, view_id: nil)`	`Array(Weakness)`
`CWE.ancestors_of(id, view_id: nil)`	`Array(Weakness)`
`CWE.descendants_of(id, view_id: nil)`	`Array(Weakness)`
`CWE.pillar_of(id)`	`Weakness?`

Categories & Views

Method	Returns
`CWE.category(id)`	`Category?`
`CWE.category!(id)`	`Category`
`CWE.categories`	`Array(Category)`
`CWE.view(id)`	`View?`
`CWE.view!(id)`	`View`
`CWE.views`	`Array(View)`
`CWE.members_of(id)`	`Array(Weakness)` (resolved members of a Category or View)

Metadata

Method	Returns
`CWE.catalog`	`Catalog`
`CWE.catalog_version`	`String` (e.g. `"4.20"`)
