WebAn implementation of the Radix Tree data structure in Java. A radix tree maps strings to values, allowing efficient string lookup and prefix queries. This implementation mostly implements the java.util.Map interface, minus the following: keySet, values, and entrySet methods currently return new sets rather than views. License

Redis Radix Tree Example Omar Qunsul

A common extension of radix trees uses two colors of nodes, 'black' and 'white'. To check if a given string is stored in the tree, the search starts from the top and follows the edges of the input string until no further progress can be made. If the search string is consumed and the final node is a black node, the search has failed; if it is white, the search has succeeded. This enables us to add a large range of strings with a common prefix to the tree, using white nodes, then remove a smal… WebDec 8, 2024 · This library provides a Go implementation of the Adaptive Radix Tree (ART).
