Detailed Description

template<class T, class Key = word, class Hash = string::hash>
class Foam::HashTable< T, Key, Hash >

An STL-conforming hash table.

Note: Hashing index collisions are handled via chaining using a singly-linked list with the colliding entry being added to the head of the linked list. Thus copying the hash table (or indeed even resizing it) will often result in a different hash order. Use a sorted table-of-contents when the hash order is important.
