Detailed Description

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.

Member Function Documentation

void ndn::BoostInfoTree::addSubtree	(	const std::string &	treeName,
		const ptr_lib::shared_ptr< BoostInfoTree > &	newTree
	)

Insert a BoostInfoTree as a sub-tree with the given name.

Parameters

treeName	The name of the new sub-tree.
newTree	The sub-tree to add.

const BoostInfoTree & ndn::BoostInfoTree::createSubtree	(	const std::string &	treeName,
		const std::string &	value = ""
	)

Create a new BoostInfo and insert it as a sub-tree with the given name.

Parameters

treeName	The name of the new sub-tree.
value	The value associated with the new sub-tree.

Returns

The created sub-tree.

const std::string* ndn::BoostInfoTree::getFirstValue ( const std::string &  key ) const

inline

Look up using the key and return string value of the first subtree.

Parameters

key	The key which may be a path separated with '/'.

Returns

A pointer to the string value or 0 if not found. Note that this pointer may no longer be valid after this BoostInfoTree is modified.

vector< const BoostInfoTree * > ndn::BoostInfoTree::operator[]

(

const std::string &

key

)

const

Look up using the key and return a list of the subtrees.

Parameters

key	The key which may be a path separated with '/'.

Returns

A new vector with pointers to the subtrees.
