getChildIteratorAtLevel in class ZipArchiveDataNode

Parameters:

level - the required starting substring of the name of all ZipEntries to be represented in the result

parent - the DataNode whose children the resulting nodes will be

Returns:

an Iterator over DataNode objects corresponding to the ZipEntry objects specified by level

Throws:

IOException
