Detailed Description

template<typename MemberType, typename TParameterType, TParameterType parameter_type_param, BufferModifiability modifiability, BufferOwnership ownership, BufferType buffer_type_param>
class kamping::internal::GenericDataBuffer< MemberType, TParameterType, parameter_type_param, modifiability, ownership, buffer_type_param >

A more generic version of a DataBuffer which stores an object of type.

Template Parameters

MemberType	with its associcated
ParameterType.	In difference to DataBuffer, GenericDataBuffer does not require the wrapped object to expose neither data(), resize() nor value_type.
MemberType	Type of the wrapped object.
TParameterType	Type of the parameter_type_param (required for parameter selection within plugins).
parameter_type_param	Parameter type represented by this buffer.
modifiability	modifiable if a KaMPIng operation is allowed to modify the underlying container. constant otherwise.
ownership	owning if the buffer should hold the object. referencing if only a reference to an existing object should be held.
buffer_type_param	Type of buffer, i.e., in_buffer, out_buffer, or in_out_buffer.
