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