Examples of configurationAt()

org.apache.commons.configuration.HierarchicalConfiguration.configurationAt()

Returns a hierarchical subnode configuration object that wraps the configuration node specified by the given key. This method provides an easy means of accessing sub trees of a hierarchical configuration. In the returned configuration the sub tree can directly be accessed, it becomes the root node of this configuration. Because of this the passed in key must select exactly one configuration node; otherwise an IllegalArgumentException will be thrown.

The difference between this method and the {@link #subset(String)} method is that subset() supports arbitrary subsets of configuration nodes while configurationAt() only returns a single sub tree. Please refer to the documentation of the SubnodeConfiguration class to obtain further information about subnode configurations and when they should be used.

With the supportUpdate flag the behavior of the returned SubnodeConfiguration regarding updates of its parent configuration can be determined. A subnode configuration operates on the same nodes as its parent, so changes at one configuration are normally directly visible for the other configuration. There are however changes of the parent configuration, which are not recognized by the subnode configuration per default. An example for this is a reload operation (for file-based configurations): Here the complete node set of the parent configuration is replaced, but the subnode configuration still references the old nodes. If such changes should be detected by the subnode configuration, the supportUpdates flag must be set to true. This causes the subnode configuration to reevaluate the key used for its creation each time it is accessed. This guarantees that the subnode configuration always stays in sync with its key, even if the parent configuration's data significantly changes. If such a change makes the key invalid - because it now no longer points to exactly one node -, the subnode configuration is not reconstructed, but keeps its old data. It is then quasi detached from its parent.
@param key the key that selects the sub tree @param supportUpdates a flag whether the returned subnode configurationshould be able to handle updates of its parent @return a hierarchical configuration that contains this sub tree @see SubnodeConfiguration @since 1.5
org.apache.commons.configuration2.BaseHierarchicalConfiguration.configurationAt()
{@inheritDoc} The result of this implementation depends on the{@code supportUpdates} flag: If it is false, a plain{@code BaseHierarchicalConfiguration} is returned using the selected nodeas root node. This is suitable for read-only access to properties. Because the configuration returned in this case is not connected to the parent configuration, updates on properties made by one configuration are not reflected by the other one. A value of true for this parameter causes a tracked node to be created, and result is a {@link SubnodeConfiguration} based on this tracked node. Thisconfiguration is really connected to its parent, so that updated properties are visible on both. @see SubnodeConfiguration @throws ConfigurationRuntimeException if the key does not select a singlenode
