------------------------------------------
Summary: Add methods to HierarchicalConfiguration to obtain sub
configurations for child elements
Key: CONFIGURATION-517
URL: https://issues.apache.org/jira/browse/CONFIGURATION-517
Project: Commons Configuration
Issue Type: New Feature
Affects Versions: 1.9
Reporter: Oliver Heger
So far, there is no direct way for a hierarchical configuration to obtain all
elements contained in a given section (i.e. the child elements of a specific
key). This can be achieved by operating on a {{ConfigurationNode}} object
directly, but this is a low-level API, and for further processing of the
element's content it might be necessary to create a {{SubNodeConfiguration}}
around the node again.
Therefore, it makes sense to extend the API of {{HierarchicalConfiguration}}. A
method can be added - similar to {{configurationsAt()}} - which expects a key,
locates the corresponding node, and then creates {{SubNodeConfiguration}}
objects for all direct children of this node.
It would also be useful to provide a way to query a configuration for the name
of its root element. This makes it easier to deal with dynamic configuration
structures.
