      • getConfigProperties

        public java.util.Properties getConfigProperties()
        Specified by:
        getConfigProperties in interface Configuration
        Returns:
        the properties object that stores the configuration

      • setConfigProperties

        public void setConfigProperties​(java.util.Properties configProperties)
        Description copied from interface: Configuration
        Configuration of the script engine comes from standard Java properties. Calling this method the caller can set the properties for the configuration. The properties passed as argument will be used as configuration solely and will NOT be merged with the keys and values of other property files.

        The fact that all other, possibly already loaded properties are not taken into account does not affect the fact that the configuration implementation itself may search other sources in addition to the properties to locate values for certain configuration keys.

        Specified by:
        setConfigProperties in interface Configuration
        Parameters:
        configProperties - the configProperties to set

      • getConfigValue

        public java.util.Optional<java.lang.String> getConfigValue​(java.lang.String key)
        Description copied from interface: Configuration
        Get the value of the key.
        Specified by:
        getConfigValue in interface Configuration
        Parameters:
        key - the configuration key for which the value is looked up.
        Returns:
        the string value of the configuration or null if the key is not configured.

      • getConfigValueList

        public java.util.List<java.lang.String> getConfigValueList​(java.lang.String key)
        Description copied from interface: Configuration
        Returns a list of strings that are the values assigned to the key in the configuration. List of strings in the configuration should be defined using the notation key'.n' where 'n' starts with zero and should increment by one continuously.
        Specified by:
        getConfigValueList in interface Configuration
        Parameters:
        key - parameter
        Returns:
        the list of configured strings
