saveConfig

Saves the current configuration values to the config.yml file.

This method performs a complete configuration save operation, writing all current configuration values from memory back to the configuration file. This is useful for programmatic configuration changes or configuration management commands.

Save Operation Process:

1. Database Configuration Saving:

• Writes all database connection parameters to their respective keys

• Includes host, port, database name, credentials, and SSL settings

• Preserves connection pool size and other performance settings

2. Debug Configuration Saving:

• Saves debug mode enablement flag

• Preserves log level settings for consistent debugging

3. Gameplay Settings Saving:

• Writes welcome message system configuration

• Preserves autosave interval and other gameplay settings

4. File Persistence:

• Calls plugin.saveConfig() to write changes to disk

• Ensures atomic file operations to prevent corruption

• Maintains YAML formatting and structure

Configuration Sections Written:

Database Section:

• database.host: MySQL server hostname or IP address

• database.port: MySQL server port number

• database.name: Database schema name

• database.username: Database authentication username

• database.password: Database authentication password

• database.useSSL: SSL encryption enablement flag

• database.connectionPoolSize: HikariCP connection pool size

Debug Section:

• debug.enabled: Debug mode enablement flag

• debug.logLevel: Logging verbosity level

Settings Section:

• settings.enableWelcomeMessage: Welcome message system enablement

• settings.welcomeMessage: Welcome message template

• settings.autosave_interval_minutes: Automatic save interval

Use Cases:

• Administrative commands that modify configuration

• Plugin setup wizards or configuration GUIs

• Programmatic configuration management

• Migration or upgrade procedures

Thread Safety: This method should be called from the main server thread to ensure thread safety with Bukkit's configuration system and file operations.

Error Handling:

• File I/O errors are handled by Bukkit's configuration system

• Malformed configuration values are written as provided

• Backup of existing configuration is handled by Bukkit

Performance Considerations:

• Configuration saving involves file I/O and should be used judiciously

• Frequent configuration saves may impact server performance

• Configuration changes take effect immediately after loading

Data Integrity:

• Bukkit's configuration system provides atomic file operations

• Original configuration file is preserved during save operations

• YAML structure and formatting are maintained
