Returns the ConfigurationInterpolator object that manages the lookup objects for resolving variables.

Usage

From source file:org.seedstack.seed.core.internal.application.ApplicationPlugin.java

private Configuration buildConfiguration(Props props, Props propsOverride,
        Map<String, Class<? extends StrLookup>> configurationLookups, String... profiles) {
    Map<String, String> finalConfiguration = new HashMap<String, String>();
    Map<String, String> configurationMap = new HashMap<String, String>();
    Map<String, String> configurationOverrideMap = new HashMap<String, String>();

    // Extract props to maps
    props.extractProps(configurationMap, profiles);
    propsOverride.extractProps(configurationOverrideMap, profiles);

    // Put defaults to final configuration
    finalConfiguration.putAll(defaultConfiguration);

    // Put nominal to final configuration
    finalConfiguration.putAll(configurationMap);

    // Apply removal behavior
    Iterator<Map.Entry<String, String>> overrideIterator = configurationOverrideMap.entrySet().iterator();
    while (overrideIterator.hasNext()) {
        String overrideKey = overrideIterator.next().getKey();
        if (overrideKey.startsWith("-")) {
            finalConfiguration.remove(overrideKey.substring(1));
            overrideIterator.remove();//from   ww w  . java  2  s. c o m
        }
    }

    // Put override to final configuration
    finalConfiguration.putAll(configurationOverrideMap);

    // Convert final configuration to an immutable Apache Commons Configuration
    MapConfiguration mapConfiguration = new MapConfiguration(
            new ImmutableMap.Builder<String, Object>().putAll(finalConfiguration).build());

    // Register configuration lookups
    for (Entry<String, Class<? extends StrLookup>> configurationLookup : configurationLookups.entrySet()) {
        mapConfiguration.getInterpolator().registerLookup(configurationLookup.getKey(),
                buildStrLookup(configurationLookup.getValue(), mapConfiguration));
    }

    return mapConfiguration;
