TypeInfo

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

class TypeInfo {

Functions

argTypes int argTypes(TypeInfo arg1, TypeInfo arg2): Return internal info on arguments fitting into 8byte. See X86-64 ABI 3.2.3
compare int compare(void* p1, 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(void* p1, void* p2): Compares two instances for equality.
getHash size_t getHash(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.
initializer const(void)[] initializer(): Undocumented in source.
offTi const(OffsetTypeInfo)[] offTi(): Get type information on the contents of the type; null if not available
opEquals bool opEquals(Object o): Undocumented in source. Be warned that the author may not have intended to support it.
postblit void postblit(void* p): Run the postblit on the object and all its sub-objects
swap void swap(void* p1, void* p2): Swaps two instances of the type.
toHash size_t toHash(): Undocumented in source. Be warned that the author may not have intended to support it.
toString string toString(): Undocumented in source. Be warned that the author may not have intended to support it.

Properties

flags uint flags [@property getter]: Get flags for type: 1 means GC should scan for pointers, 2 means arg of this type is passed in XMM register
next inout(TypeInfo) next [@property getter]: Get TypeInfo for 'next' type, as defined by what kind of type this is, null if none.
rtInfo immutable(void)* rtInfo [@property getter]: Return info used by the garbage collector to do precise collection.
talign size_t talign [@property getter]: Return alignment of type
tsize size_t tsize [@property getter]: Returns size of the type.
