Member Function Documentation

void* qi::TypeImpl< void >::clone ( void *  )

inlinevirtual

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 *  )

inlinevirtual

Free all resources of a storage.

Implements qi::TypeInterface.

Definition at line 318 of file typeimpl.hxx.

const TypeInfo& qi::TypeImpl< void >::info ( )

inlinevirtual

Get the TypeInfo corresponding to this type.

Implements qi::TypeInterface.

Definition at line 310 of file typeimpl.hxx.

void* qi::TypeImpl< void >::initializeStorage ( void *  ptr )

inlinevirtual

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 ( )

inlinevirtual

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  )

inlinevirtual

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 **  )

inlinevirtual

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.

Definition at line 316 of file typeimpl.hxx.
