Class `object.TypeInfo_Class`

Runtime type information about a class. Can be retrieved from an object instance by using the .classinfo property.


						
				class TypeInfo_Class
				
  : TypeInfo
				;

Fields

Name	Type	Description
`base`	`TypeInfo_Class`	base class
`interfaces`	`Interface[]`	interfaces this class implements
`m_init`	`byte[]`	class static initializer (init.length gives size in bytes of class)
`name`	`string`	class name
`vtbl`	`void*[]`	virtual function pointer table

Properties

Name	Type	Description
`flags`[get]	`uint`	Get flags for type: 1 means GC should scan for pointers, 2 means arg of this type is passed in SIMD register(s) if available
`next`[get]	`inout(TypeInfo)`	Get TypeInfo for 'next' type, as defined by what kind of type this is, null if none.
`rtInfo`[get]	`immutable(void)*`	Return info used by the garbage collector to do precise collection.
`talign`[get]	`ulong`	Return alignment of type
`tsize`[get]	`ulong`	Returns size of the type.

Methods

Name	Description
`create` ()	Create instance of Object represented by 'this'.
`find` (classname)	Search all modules for TypeInfo_Class corresponding to classname.
`isBaseOf` (child)	Returns true if the class described by `child` derives from or is the class described by this `TypeInfo_Class`. Always returns false if the argument is null.
`argTypes` (arg1, arg2)	Return internal info on arguments fitting into 8byte. See X86-64 ABI 3.2.3
`compare` ()	Compares two instances for <, ==, or >.
`destroy` (p)	Run the destructor on the object and all its sub-objects
`equals` ()	Compares two instances for equality.
`factory` (classname)	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`getHash` (p)	Computes a hash of the instance of a type.
`initializer` ()	Return default initializer. If the type should be initialized to all zeros, an array with a null ptr and a length equal to the type size will be returned. For static arrays, this returns the default initializer for a single element of the array, use `tsize` to get the correct size.
`offTi` ()	Get type information on the contents of the type; null if not available
`opCmp` (o)	Compare with another Object obj.
`opEquals` (o)	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides for `opEquals` should attempt to compare objects by their contents.
`postblit` (p)	Run the postblit on the object and all its sub-objects
`swap` (p1, p2)	Swaps two instances of the type.
`toHash` ()	Compute hash function for Object.
`toString` ()	Convert Object to a human readable string.
