Member Function Documentation

◆ GetId()

const Id& GetId ( ) const

Returns the identifier of this data type. Data type identifiers of primary types look like int32, pointer types are identified by a * suffix as in {float64*}, tuple types by a parenthesized list of its member types as in {(int32,float64*)}.

Returns: Unique identifier of this type.

◆ ToString() [1/2]

String ToString ( const FormatStatement * formatStatement = nullptr ) const

Returns a String representation of this @CLASS.

Parameters

[in] formatStatement Nullptr or additional formatting instruction.

Returns: String representation of this @CLASS.

◆ GetSize()

Int GetSize ( ) const

Returns the size of values of this data type.

Returns: Size of values.

◆ GetAlignment()

Int GetAlignment ( ) const

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

Returns: Alignment of values.

◆ GetValueKind()

VALUEKIND GetValueKind ( ) const

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).

Parameters

[in] test The flags to test.

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(). Even with HasTypeArguments() returning true, GetTypeArguments().count can be 0 for types like ArrayContainer<>. Hence one often has to perform this kind of double validation.

if (type.HasTypeArguments() && type.GetTypeArguments().count > 0)
{
  auto firstMemberType = type.GetTypeArguments().args[0];
  // ...
}

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.

Returns: SimdInfo of this type.

◆ GetImplementation()

const NonvirtualInterfaceImplementation* GetImplementation ( ) const

Returns the interface implementation of this type as nullptr-terminated array. This function may only be invoked if this type is an interface type.

Returns: The interface implementation of this interface type.

◆ GetInterfaces()

const InterfaceDefinition* const* GetInterfaces ( ) const

Returns the interfaces of this object type as nullptr-terminated array. This function may only be invoked if this type is an object type.

Returns: The interfaces of this object type.

◆ GetNullValue()

const Generic* GetNullValue ( ) const

Returns a pointer to a default-constructed object of this type.

Returns: Pointer to default-constructed object of this type, or nullptr in case of an error (for example if type is abstract).

◆ Create()

Result<void*> Create ( ) const

Creates a new instance of this type.

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.
Otherwise, the new instance will be initialized by the default constructor. For reference types, this means that the reference will point to nullptr.
Returns
New instance of this data type. The caller owns the new instance.
