Detailed Description

Configuration storage using SQLite.

This implementation of the Configuration interface uses SQLite to store the configuration.

The configuration uses two databases, one is used to store the host-specific configuration and the other one is used to store the default values. Only the default database is meant to reside under version control.

See init() for the structure of the databases. This class strictly serializes all accesses to the database such that only one thread at a time can modify the database.


Member Enumeration Documentation

Transaction type.

See SQLite Documentation for BEGIN TRANSACTION.

Enumerator:
TRANSACTION_DEFERRED 

Deferred transaction, lock acquired late.

TRANSACTION_IMMEDIATE 

Immediately acquire lock, reading remains possible.

TRANSACTION_EXCLUSIVE 

Immediately acquire lock, no more reading or writing possible.

Definition at line 100 of file sqlite.h.
