Function Documentation

◆ VtGetKnownValueTypeIndex()

constexpr int VtGetKnownValueTypeIndex ( )
constexpr

Provide compile-time value type indexes for types that are "known" to Vt – specifically, those types that appear in VT_VALUE_TYPES.

Note that VtArray and VtValue can work with other types that are not these "known" types.

VtGetKnownValueTypeIndex can only be used with known types. Querying a type that is not known to Vt results in a compilation error. The set of known types and their indexes are not guaranteed to be stable across releases of the library.

Most clients should prefer VtVisitValue over direct use of the type index as VtVisitValue provides convenient and efficient access to the held value.

Definition at line 236 of file types.h.

◆ VtGetNumKnownValueTypes()

constexpr int VtGetNumKnownValueTypes ( )
constexpr

Definition at line 218 of file types.h.

◆ VtIsKnownValueType()

constexpr bool VtIsKnownValueType ( )
constexpr

Returns true if T is a type that appears in VT_VALUE_TYPES.
