Public Member Functions
	AvailableConnections (Class<? extends DatabaseConnection > clazz)

Detailed Description

The AvailableConnections enum defines the supported database connections (SQLITE, POSTGRES, MSACCESS) and provides a method to retrieve a database connection instance based on the selected type.

Each enum constant corresponds to a specific database connection implementation, and upon initialization, it tries to instantiate the associated connection class using reflection.

The getConnection() method retrieves a configured connection instance, ensuring that the necessary configuration properties are available before establishing a connection.

The supported connection types are:

• SQLITE - SQLite database connection.
• POSTGRES - PostgreSQL database connection.
• MSACCESS - MS Access database connection.
