Partition
common/Partition.hpp
This type provides a concrete Partition of memory-slots capable of holding any of the specified list of types. The Partition is not aware of the types stored in the Partition memory, hence it provides no mechanism for deleting C++ objects when the Partition is clear()'ed.
This class implements AbstractPartition.
Template Parameters:
- ListOfTypes Type of the list of types.
- NUMBER_OF_ELEMENTS Type of the number of elements.

Public Types
| enum | @0 { INTS_PR_ELEMENT = (sizeof(typename meta::select_type_maxsize<SupportedTypesList>::type) + sizeof(int) - 1) / sizeof(int), SIZE_OF_ELEMENT = INTS_PR_ELEMENT * sizeof(int) } |
| Compile-time generated constants specifying the "element" or "slot" size used by this partition. | |
| typedef ListOfTypes | SupportedTypesList |
| Provides a generic public type containing the list of supported types. | |
Public Functions
| virtual uint16_t | capacity() const |
| Gets the capacity, i.e. | |
| virtual uint32_t | element_size() |
| Access to concrete element-size. | |
Protected Functions
| virtual void * | element(uint16_t index) |
| Access to stored element. | |
| virtual const void * | element(uint16_t index) const |
| Access to stored element, const version. | |
