Class `object.TypeInfo_Class`

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


						
				class TypeInfo_Class
				
  : TypeInfo
				;

Fields

Name	Type	Description
`base`	`TypeInfo_Class`	base class
`depth`	`ushort`	inheritance distance from Object
`interfaces`	`Interface[]`	interfaces this class implements
`m_init`	`byte[]`	class static initializer (init.length gives size in bytes of class)
`name`	`string`	class name
`nameSig`	`uint[4]`	unique signature for `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 and overloads for `opEquals` should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for `null` on the typed overload.
`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.
