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

NameTypeDescription
base TypeInfo_Classbase class
interfaces Interface[]interfaces this class implements
m_init byte[]class static initializer (init.length gives size in bytes of class)
name stringclass name
vtbl void*[]virtual function pointer table

Properties

NameTypeDescription
flags[get] uintGet flags for type: 1 means GC should scan for pointers, 2 means arg of this type is passed in XMM register
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] ulongReturn alignment of type
tsize[get] ulongReturns size of the type.

Methods

NameDescription
create Create instance of Object represented by 'this'.
find Search all modules for TypeInfo_Class corresponding to classname.
argTypes Return internal info on arguments fitting into 8byte. See X86-64 ABI 3.2.3
compare Compares two instances for <, ==, or >.
destroy Run the destructor on the object and all its sub-objects
equals Compares two instances for equality.
factory Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
getHash 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 Compare with another Object obj.
opEquals 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 Run the postblit on the object and all its sub-objects
swap Swaps two instances of the type.
toHash Compute hash function for Object.
toString Convert Object to a human readable string.
