Class BoostInfoTree

java.lang.Object

net.named_data.jndn.util.BoostInfoTree

public class BoostInfoTree
extends Object

BoostInfoTree is provided for compatibility with the Boost INFO property list format used in ndn-cxx. Each node in the tree may have a name and a value as well as associated sub-trees. The sub-tree names are not unique, and so sub-trees are stored as dictionaries where the key is a sub-tree name and the values are the sub-trees sharing the same name. Nodes can be accessed with a path syntax, as long as nodes in the path do not contain the path separator '/' in their names.
