SqliteConnection

SQLite connection using the default driver.

Implements: IReferenceable, IConfigurable, IOpenable

Description

The SqliteConnection class allows you to create SQLite connections using the default driver.

Important points

By defining a connection and sharing it through multiple persistence components you can reduce the number of used database connections.

Configuration parameters

  • connection(s):
    • discovery_key: (optional) key to retrieve the connection from IDiscovery
    • database: database file path
    • uri: resource URI with file:// protocol

References

  • *:logger:*:*:1.0 - (optional) ILogger components to pass log messages
  • *:discovery:*:*:1.0 - (optional) IDiscovery services
  • *:credential-store:*:*:1.0 (optional) credential stores to resolve credentials
