org.apache.commons.configuration.interpol.InterpolatorSpecification

A simple value class defining a {@link ConfigurationInterpolator}.

Objects of this class can be used for creating new {@code ConfigurationInterpolator} instances; they contain all requiredproperties. It is either possible to set a fully initialized {@code ConfigurationInterpolator} directly which can be used as is.Alternatively, some or all properties of an instance to be newly created can be set. These properties include

a map with {@code Lookup} objects associated with a specific prefix
a collection with default {@code Lookup} objects (without a prefix)
a parent {@code ConfigurationInterpolator}

When setting up a configuration it is possible to define the {@code ConfigurationInterpolator} in terms of this class. The configurationwill then either use the {@code ConfigurationInterpolator} instanceexplicitly defined in the {@code InterpolatorSpecification} instance orcreate a new one.

Instances are not created directly, but using the nested {@code Builder}class. They are then immutable.
