Method Detail

convertToConcurrentCompositeConfiguration

public static ConcurrentCompositeConfiguration convertToConcurrentCompositeConfiguration(org.apache.commons.configuration.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,org.apache.commons.configuration.Configuration> getAllNamedConfiguration(org.apache.commons.configuration.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(org.apache.commons.configuration.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,
                                  org.apache.commons.configuration.Configuration config)

getConfigFromPropertiesFile
