Detailed Description

template<class T_R>
class DBCache< T_R >

This is the interface class of a database cacher.

A transaction cacher is actually a wrapper around a transaction reader (see: class TransactionReader). In general a database cacher collects the same transactions together and stores them in an efficient way. You can get each transaction one-by-one. For this use nextTransactionBIS or nextTransactionUAC methods.

There are many transaction cacher. They differ in the data structure that stores the transactions.

• OrderedVectorDBCache stores the transactions in a simple ordered vector,
• OrderedArrayDBCache stores the transactions in a vector of ordered vectors,
• TrieDBCache stores the transactions in a general trie,
• RBTreeDBCache is a transaction cacher that store the transactions in a red-black tree,
• BuildTreeDBCache is a Patricia trie database cacher.
