Class Generated::PackType

An actual type of a pack expression at the instatiation point.

In the following example, PackType will appear around makeTuple call site as Pack{String, Int}:

func makeTuple<each T>(_ t: repeat each T) -> (repeat each T) { ... }
makeTuple("A", 2)

PackType

Predicates

getAPrimaryQlClass	Gets the name of a primary CodeQL class to which this element belongs.
getAnElement	Gets any of the elements of this pack type.
getElement	Gets the `index`th element of this pack type (0-based).
getImmediateElement	Gets the `index`th element of this pack type (0-based).
getNumberOfElements	Gets the number of elements of this pack type.

Inherited predicates

getABaseType	Gets any base type of this type. Expands protocols added in extensions and expands type aliases. For example in the following code, `B` has base type `A`:	from Type
getADerivedType	Gets a type derived from this type. Expands type aliases, for example in the following code, `B` derives from type `A`.	from Type
getCanonicalType	Gets the canonical type of this type.	from Type
getFullName	Gets the full name of this `Type`. For example in: `swift struct A { struct B { // ... } }` The name and full name of `A` is `A`. The name of `B` is `B`, but the full name of `B` is `A.B`.	from Type
getFullyUnresolved		from Element
getImmediateCanonicalType	Gets the canonical type of this type.	from Type
getName	Gets the name of this type.	from Type
getPrimaryQlClasses	Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.	from Element
getResolveStep	Gets the most immediate element that should substitute this element in the explicit AST, if any. Classes can override this to indicate this node should be in the “hidden” AST, mostly reserved for conversions and syntactic sugar nodes like parentheses.	from Element
getUnderlyingType	Gets this type after any type aliases have been resolved. For example in the following code, the underlying type of `MyInt` is `Int`: `typealias MyInt = Int`	from Type
isUnknown	Holds if this element is unknown.	from Element
resolve	Gets the element that should substitute this element in the explicit AST, applying `getResolveStep` transitively.	from Element
toString	Gets the string representation of this element.	from Type
