Class object.TypeInfo

Runtime type information about a type. Can be retrieved for any type using a TypeidExpression.

class TypeInfo ;


flags[get] uintGet 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] ulongReturn alignment of type
tsize[get] ulongReturns size of the type.


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.
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
postblit (p) Run the postblit on the object and all its sub-objects
swap (p1, p2) Swaps two instances of the type.
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.
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.
toHash () Compute hash function for Object.
toString () Convert Object to a human readable string.
