Method Detail

loadConfiguration

public static Configuration loadConfiguration()

Loads the global configuration from the environment. Fails if an error occurs during loading. Returns an empty configuration object if the environment variable is not set. In production this variable is set but tests and local execution/debugging don't have this environment variable set. That's why we should fail if it is not set.

Returns:

Returns the Configuration

loadConfiguration

public static Configuration loadConfiguration(Configuration dynamicProperties)

Loads the global configuration and adds the given dynamic properties configuration.

Parameters:

dynamicProperties - The given dynamic properties

Returns:

Returns the loaded global configuration with dynamic properties

loadConfiguration

public static Configuration loadConfiguration(String configDir)

Loads the configuration files from the specified directory.

YAML files are supported as configuration files.

Parameters:

configDir - the directory which contains the configuration files

loadConfiguration

public static Configuration loadConfiguration(String configDir,
                                              @Nullable
                                              Configuration dynamicProperties)

Loads the configuration files from the specified directory. If the dynamic properties configuration is not null, then it is added to the loaded configuration.

Parameters:

configDir - directory to load the configuration from

dynamicProperties - configuration file containing the dynamic properties. Null if none.

Returns:

The configuration loaded from the given configuration directory

isSensitive
