## Public Types

- typedef Key key_type
    Each map entry is stored in a linked list where an entry consists of a pointer to the key/value pair and a flag to indicate whether the entry has been erased.
- typedef Value data_type
- typedef size_t size_type
- typedef XALAN_STD_QUALIFIER
  pair< const key_type, data_type > value_type
- typedef XalanList< Entry > EntryListType
- typedef XalanVector< typename
  EntryListType::iterator > BucketType
- typedef XalanVector< BucketType,
  ConstructWithMemoryManagerTraits<
  BucketType > > BucketTableType
- typedef XalanMapIterator<
  XalanMapIteratorTraits< value_type >,
  typename EntryListType::iterator > iterator
- typedef XalanMapIterator<
  XalanMapConstIteratorTraits<
  value_type >, typename EntryListType::iterator > const_iterator
- typedef MemoryManagedConstructionTraits<
  key_type >::Constructor FirstConstructor
- typedef MemoryManagedConstructionTraits<
  data_type >::Constructor SecondConstructor

| Each map entry is stored in a linked list where an entry consists of a pointer to the key/value pair and a flag to indicate whether the entry has been erased. The hash buckets are a vector of pointers into the entry list. Deleted entries are spliced into another list and marked 'erased'.
