Detailed Description

template<class SET>
class SG::SetIndexingPolicy< SET >

Indexing policy for a set-like container.

See ElementLinkTraits.h for a summary of the requirements for an indexing policy.

Indexes here are use IndexHolder, with the key of the container as the payload.

Member Function Documentation

isValid()

template<class SET >

static bool SG::SetIndexingPolicy< SET >::isValid ( const stored_index_type &  index )

static

Test to see if an index is valid.

Parameters

index

The index to test.

lookup()

template<class SET >

static ElementType SG::SetIndexingPolicy< SET >::lookup ( const stored_index_type &  index, const SET &  data  )

static

Retrieve from a container the element corresponding to an index.

Parameters

index	The index to fetch.
data	The container.

Will throw SG::ExcInvalidIndex if the index is invalid and SG::ExcIndexNotFound if the index is not in the container.

reset()

template<class SET >

static void SG::SetIndexingPolicy< SET >::reset ( stored_index_type &  index )

static

Make an index invalid.

Parameters

index[out]

The index to reset.

reverseLookup()

template<class SET >

static void SG::SetIndexingPolicy< SET >::reverseLookup ( const SET &  data, ElementConstReference  element, index_type &  same  )

static

Find the index of the (first) instance of ELEMENT in DATA.

Parameters

data	The container to search.
element	The element to find.
index[out]	The index in the container of element.

Throws SG::ExcElementNotFound if the element is not in the container.

storedToExternal()

template<class SET >

static index_type SG::SetIndexingPolicy< SET >::storedToExternal ( stored_index_type  index )

static

Convert from stored to external index types.

Parameters

index

The stored index.
