## Member Function Documentation

void* qi::TypeImpl< void >::clone | ( | void * |  | ) |
| inline override virtual

Allocate a storage and copy the value given as an argument.

Implements qi::TypeInterface.

Definition at line 317 of file typeimpl.hxx.

void qi::TypeImpl< void >::destroy | ( | void * |  | ) |
| inline override virtual

Free all resources of a storage.

Implements qi::TypeInterface.

Definition at line 318 of file typeimpl.hxx.

const TypeInfo& qi::TypeImpl< void >::info | ( |  | ) |
| inline override virtual

Get the TypeInfo corresponding to this type.

Implements qi::TypeInterface.

Definition at line 308 of file typeimpl.hxx.

void* qi::TypeImpl< void >::initializeStorage | ( | void * | ptr | ) |
| inline override virtual

Initialize and return a new storage, from nothing or a T*.

If ptr is not null, it should be used as a storage (the method can usually just return ptr in that case).

Implements qi::TypeInterface.

Definition at line 315 of file typeimpl.hxx.

TypeKind qi::TypeImpl< void >::kind | ( |  | ) |
| inline override virtual

Get the kind of the data.

This is used to downcast the TypeInterface object to a specialized interface.

Reimplemented from qi::TypeInterface.

Definition at line 319 of file typeimpl.hxx.

bool qi::TypeImpl< void >::less | ( | void * | a,
|  | void * | b
| ) |  |
| inline override virtual

Return true if a is less than b

Less must always work: compare pointers if you have to.

Implements qi::TypeInterface.

Definition at line 320 of file typeimpl.hxx.

void* qi::TypeImpl< void >::ptrFromStorage | ( | void ** |  | ) |
| inline override virtual

Get pointer to type from pointer to storage.

This allows for storing an integer value (for instance) directily into the pointer and avoid an allocation.

This method should be called on storage before casting it to a specific type.

Implements qi::TypeInterface.
