Class CharTrieOfFewIgnoreCase

java.lang.Object

ch.randelshofer.fastdoubleparser.chr.CharTrieOfFewIgnoreCase

All Implemented Interfaces:

CharTrie

final class CharTrieOfFewIgnoreCase
extends Object
implements CharTrie

A trie for testing if a String is contained in a set of Strings.

This trie is a directed acyclic graph.

    Given: the strings: "NaN", "Inf"
    The trie will have the following structure:

    root ['N','n', 'I','i']
           │   │    │   │
           │   │    └─┬─┘
           │   │      └─→ node ['N','n']
           │   │                 │   │
           │   │                 └─┬─┘
           └─┬─┘                   └─→ node ['F','f']
             └─→ node ['A','a']
                        │   │
                        └─┬─┘
                          └─→ node ['N','N']
