RadixTree

What

A radix tree in c++ 14. Smart Pointer, Mutex, stl containers.

How

Feed the radixTree with the loadString method.

Alternaly, you can use the CLI. Run the tree with the -d flag and then :

• feed the tree via STDIN (or, for example, redirect a file with <)
• enter the key word start to start searching in the tree

Output example :

~/repo/sbc/src/radix/build master_1234_radix
11:07:09 ❯ ./radix_tree -d -v
Enter some key to add (or start to start to search) : dog
Enter some key to add (or start to start to search) : did
Enter some key to add (or start to start to search) : dogs
Enter some key to add (or start to start to search) : doe
Enter some key to add (or start to start to search) : start
There is 4 entries for 6 leafs.

----------[LeafID]:[1]----------
[g]/[dog] = [0]
[RootID]:	5
[ChildIDs]:	4
----------[LeafID]:[2]----------
[d]/[] = []
[RootID]:	0
[ChildIDs]:	3 5
----------[LeafID]:[3]----------
[id]/[did] = [1]
[RootID]:	2
[ChildIDs]:
----------[LeafID]:[4]----------
[s]/[dogs] = [2]
[RootID]:	1
[ChildIDs]:
----------[LeafID]:[5]----------
[o]/[] = []
[RootID]:	2
[ChildIDs]:	6 1
----------[LeafID]:[6]----------
[e]/[doe] = [3]
[RootID]:	5
[ChildIDs]:

Usage

~/repo/sbc/src/radix/build master_1234_radix
18:26:00 ❯ ./radix_tree -h -d
Usage : ./radix_tree [-v|-vv|-vvv] -h

        -v|-vv|-vvv:    Level of verbosity of the radix trie.
        -d:             Enable the cli / debug mode.
        -h:             Display this screen.

Build

Requirement

• cmake & make
• clang or gcc (c++14 compatible)

Created

• a binary file radix_tree; which is the RadixTree class compiled with a funny CLI
• a shared library, libradix.so; ready to be integrated 🤓

Use it

The RadixTree class take a void * as value indexed. To be quick, the radix tree index with std::string key and store some void * data.

Build it

$ cd build
$ cmake ../
$ # OR to build with debug flag
$ cmake ../ -DDEFINE_DEBUG_RADIX=1
$ # OR to build with debug compile flag
$ cmake ../ -DDEFINE_DEBUG_COMPILE=1
$ make -j4

TODO

• longest prefix match method 🚀
• cli match
• cli feed
