Detailed Description

template<class T>
class zserio::ppmr::PropagatingPolymorphicAllocator< T >

Propagating version of the polymorphic allocator. This one is propagated on container copy and assignment.

Constructor & Destructor Documentation

PropagatingPolymorphicAllocator() [1/4]

template<class T >

zserio::ppmr::PropagatingPolymorphicAllocator< T >::PropagatingPolymorphicAllocator ( std::pmr::memory_resource *  resource = std::pmr::get_default_resource() )

inlinenoexcept

Constructor.

Note that this is intentionally non-explicit to allow to pass MemoryResource wherever the PropagatingPolymorphicAllocator is required.

Parameters

resource

Memory resource. According to the C++ standard the resource may not be NULL. Since it implies undefined behaviour, we define a non-standard extension here. When the resource is NULL, std::pmr::get_default_resource() is used instead!

Member Function Documentation

allocate()

template<class T >

value_type * zserio::ppmr::PropagatingPolymorphicAllocator< T >::allocate ( std::size_t  size )

inline

Allocates memory for n values.

Parameters

size	Number of values to allocate memory for.

Definition at line 82 of file PropagatingPolymorphicAllocator.h.

construct()

template<class T >

template<typename U , typename... Args>

void zserio::ppmr::PropagatingPolymorphicAllocator< T >::construct ( U *  ptr, Args &&...  args  )

inline

Constructs an object in allocated memory.

Parameters

ptr	Pointer to memory where the object will be constructed.
args	Parameters to be forwarded to the object constructor.

Definition at line 106 of file PropagatingPolymorphicAllocator.h.

deallocate()

template<class T >

void zserio::ppmr::PropagatingPolymorphicAllocator< T >::deallocate ( value_type *  memory, std::size_t  size  )

inlinenoexcept

Deallocates memory for n values.

Parameters

memory	Pointer to the memory to deallocate.
size	Number of values held by the memory pointed to by memory. Shall be the same size as was used for allocation of memory.
