ConfigurationConfiguration interface the other get methods (that
return specific data types) will internally make use of this method. On
this level variable substitution is not yet performed. The returned
object is an internal representation of the property value for the passed
in key. It is owned by the Configuration object. So a caller
should not modify this object. It cannot be guaranteed that this object
will stay constant over time (i.e. further update operations on the
configuration may change its internal state).key - property to retrievepublic Iterator<String> getKeys()
Configurationremove() method is specific to
a concrete implementation. It may remove the corresponding
property from the configuration, but this is not guaranteed. In any case
it is no replacement for calling
Configuration.clearProperty(String) for this property. So it is
highly recommended to avoid using the iterator's remove()
method.public boolean isEmpty()
