Returns
Size of values.

Int GetAlignment ( ) const

Returns the alignment of values of this data type. This might by an extended alignment.

Returns
Alignment of values.

◆ GetValueKind()

Returns the kind of values of this data type. This is a coarse classification to distinguish between e.g. value types, pointers, references, arrays and tuples.

Returns
Kind of values.

◆ CheckValueKind()

Bool CheckValueKind ( VALUEKIND  test) const

Tests the value kind of this data type for the given flags (by using the bitwise and).

Returns
True if the value kind of this data type has one of the given flags, false otherwise.

◆ GetUnqualifiedType()

const DataTypeImpl* GetUnqualifiedType ( ) const

Returns the unqualified type of this data type. Currently the only possible qualification is a const qualification. So when this data type represents const T, the returned data type represents T. If the type is already an unqualified type, this functions returns the type itself.

Returns
This type with any qualifications removed (or this type itself if it is already unqualified).

◆ GetUnderlyingType()

const DataType& GetUnderlyingType ( ) const

Returns the underlying type of this data type. The underlying data type is a layout-compatible more fundamental type, such as the unqualified version T for const T, or the tuple type Tuple<T, T, T> for Vec3<T>.

Returns
The underlying type of this type, or nullptr.

◆ GetElementType()

const DataType& GetElementType ( ) const

Returns the element type of this data type. The element type is used for some parametric types such as pointers or references, so for example the element type of {T*} or {StrongRef<T>} is T.

Returns
The element type of this type, or nullptr.

◆ GetDecayedType()

const DataTypeImpl* GetDecayedType ( ) const

Returns the decayed type of this data type (in the sense of std::decay). I.e., at first this removes any l- or r-value-reference-qualification, and then it returns the unqualified type of the result.

Returns
The decayed type of this type, maybe this type itself.

◆ HasTypeArguments()

Bool HasTypeArguments ( ) const

Returns true if this data type has valid type arguments, so that it is legal to call GetTypeArguments().

Returns
True if this type has valid type arguments, false otherwise.

◆ GetTypeArguments()

const TypeArguments& GetTypeArguments ( ) const

Returns the type arguments of this data type. Type arguments are set for some instantiations of parametric types. For example, the 3-dimensional Vector is an instantiation of the parametric type Vec with the arguments (Float, 3).

Returns
The type arguments of this type.

◆ GetParametricType()

const ParametricTypeInterface* GetParametricType ( ) const

Returns the parametric type which instantiated this type. For example if this type is Vector, the function returns the parametric type Vec.

Returns
The parametric type which instantiated this type, or nullptr.

◆ GetSimdInfo()

const SimdInfo& GetSimdInfo ( ) const

Returns the SimdInfo of this type. This type has to be a SIMD type (or a qualified version thereof), otherwise the behavior is undefined.

  • If this type is a non-virtual interface, the new instance will be created by NewObj.
  • If this type is an array type TODO: (Ole) implement
  • If this type is a virtual interface type, an error is returned because only classes can be instantiated, not interfaces.
