Detailed Description

Defines several indirection policies for slam.

Indirection policies encompass the underlying storage for indirection buffers for a SLAM set, relation or map. A valid indirection policy must support the following interface:

• [required]
• type alias IndirectionResult – the type of the result of an indirection (const/nonconst and ref/nonref)
• indirection() : IntType – returns the value of the element after indirection
• hasIndirection(): bool – returns whether there is an indirection buffer
• isValid() : bool – indicates whether the Indirection policy of the set is valid
• [optional]
  • operator(): IntType – alternate accessor for indirection
  • data() : ElementType* – allows direct access to the underlying buffer (when this exists)

Note

Slam's Sets, Relations and Maps are not responsible for allocating/deallocating their own memory
