com.etherios.connector.preferences.configuration.ConfigurationManager

public class ConfigurationManager
extends java.lang.Object

This class takes care of reading and writing all the configuration parameters of Cloud Connector from the record store or from the configuration file connector_config.txt.

When reading a setting it first look for it in the record store, if it is not there the configuration file is read.

The path of the configuration file can be provided as a parameter in the constructor of the object or specifying the system property "connector.config.file.path". If none of them is defined the file embedded in the jar will be used.

The methods in this class are used by the PreferencesManager class to get the Connector Configuration values and by the DefaultConnectorLogger class to get the logging configuration.

The list of parameters is found at PreferencesConstants
