TypeInfo

Runtime type information about a type. Can be retrieved for any type using a $(GLINK2 expression,TypeidExpression, TypeidExpression).

class TypeInfo {

size_t getHash(scope const void* p);

bool equals(in void* p1, in void* p2);

int compare(in void* p1, in void* p2);

size_t tsize();

void swap(void* p1, void* p2);

inout(TypeInfo) next();

const(void)[] initializer();

uint flags();

const(OffsetTypeInfo)[] offTi();

void destroy(void* p);

void postblit(void* p);

size_t talign();

int argTypes(out TypeInfo arg1, out TypeInfo arg2);

immutable(void)* rtInfo();

}

Functions

argTypes int argTypes(out TypeInfo arg1, out TypeInfo arg2): Return internal info on arguments fitting into 8byte. See X86-64 ABI 3.2.3
compare int compare(in void* p1, in void* p2): Compares two instances for <, ==, or >.
destroy void destroy(void* p): Run the destructor on the object and all its sub-objects
equals bool equals(in void* p1, in void* p2): Compares two instances for equality.
flags uint flags(): Get flags for type: 1 means GC should scan for pointers, 2 means arg of this type is passed in XMM register
getHash size_t getHash(scope const void* p): Computes a hash of the instance of a type.
initializer const(void)[] 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.
next inout(TypeInfo) next(): Get TypeInfo for 'next' type, as defined by what kind of type this is, null if none.
offTi const(OffsetTypeInfo)[] offTi(): Get type information on the contents of the type; null if not available
postblit void postblit(void* p): Run the postblit on the object and all its sub-objects
rtInfo immutable(void)* rtInfo(): Return info used by the garbage collector to do precise collection.
swap void swap(void* p1, void* p2): Swaps two instances of the type.
talign size_t talign(): Return alignment of type
tsize size_t tsize(): Returns size of the type.
