Method Detail

convertToConcurrentCompositeConfiguration

public static ConcurrentCompositeConfiguration convertToConcurrentCompositeConfiguration(CombinedConfiguration config)

Convert CombinedConfiguration into ConcurrentCompositeConfiguration as the later has better performance and thread safety.

Parameters:

config - Configuration to be converted

getAllNamedConfiguration

public static java.util.Map<java.lang.String,Configuration> getAllNamedConfiguration(Configuration conf)

Gets all named sub-configuration from a configuration in a map. This method examines each sub-configuration which is an instance of ConcurrentCompositeConfiguration or CombinedConfiguration and extract the named configurations out of them.

Parameters:

conf - Configuration to get all the named sub-configurations

Returns:

map where key is the name of the sub-configuration and value is the sub-configuration

getProperties

public static java.util.Properties getProperties(Configuration config)

Utility method to obtain Properties given an instance of AbstractConfiguration. Returns an empty Properties object if the config has no properties or is null.

Parameters:

config - Configuration to get the properties

Returns:

properties extracted from the configuration

loadProperties

public static void loadProperties(java.util.Properties props,
                                  Configuration config)

getConfigFromPropertiesFile
