Creates a CompositeConfiguration object with a specified in memory
configuration.
|
CompositeConfiguration(Configuration inMemoryConfiguration,
Collection configurations)
Creates a CompositeConfiguration with a specified in memory
configuration, and then adds the given collection of configurations.

remove()
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.getKeys
