Typedef Documentation

EntrySelector

using nfd::name_tree::EntrySelector = typedef std::function<bool(const Entry&)>

a predicate to accept or reject an Entry in find operations

Definition at line 38 of file name-tree-iterator.hpp.

EntrySubTreeSelector

using nfd::name_tree::EntrySubTreeSelector = typedef std::function<std::pair<bool, bool>(const Entry&)>

a predicate to accept or reject an Entry and its children

Returns

.first indicates whether entry should be accepted; .second indicates whether entry's children should be visited

Definition at line 55 of file name-tree-iterator.hpp.

HashFunc

using nfd::name_tree::HashFunc = typedef std::conditional<(sizeof(HashValue) > 4), Hash64, Hash32>::type

a type with compute static method to compute hash value from a raw buffer

Definition at line 57 of file name-tree-hashtable.cpp.

HashSequence

using nfd::name_tree::HashSequence = typedef std::vector<HashValue>

a sequence of hash values

See also

computeHashes

Definition at line 43 of file name-tree-hashtable.hpp.

HashValue

using nfd::name_tree::HashValue = typedef size_t

a single hash value

Definition at line 38 of file name-tree-hashtable.hpp.

Range

using nfd::name_tree::Range = typedef boost::iterator_range<Iterator>

a Forward Range of name tree entries

This type has .begin() and .end() methods which return Iterator. This type is usable with range-based for.

Function Documentation

computeHash()

HashValue nfd::name_tree::computeHash	(	const Name &	name,
		size_t	prefixLen
	)

computes hash value of name.getPrefix(prefixLen)

computeHashes()

HashSequence nfd::name_tree::computeHashes	(	const Name &	name,
		size_t	prefixLen = std::numeric_limits< size_t >::max()
	)

computes hash values for each prefix of name.getPrefix(prefixLen)

Returns

a hash sequence, where the i-th hash value equals computeHash(name, i)

foreachNode()

template<typename N , typename F >

void nfd::name_tree::foreachNode	(	N *	head,
		const F &	func
	)

Template Parameters

N	either Node or const Node
F	a functor with signature void F(N*)

Note

It's safe to delete the node in the function.

Definition at line 94 of file name-tree-hashtable.hpp.
