Detailed Description

Demonstrates some uses of the Symbian platform hash table APIs of the User Library component.

The class demonstrates how to construct and operate a hash set, a hash set of pointers, a hash map and a hash map of pointers.

• Construction of these includes
  • using the default hash and identity functions for integers and for descriptors
  • providing custom hash and identity functions
• Operation of these includes
  • inserting items
  • finding items
  • removing items
  • iterating through items
  • closing and cleanup
