JavaScript implementation of Double-Array trie.
Node.js example
var doublearray = require('./doublearray.js');
var words = [
{ k: 'a', v: 1 },
{ k: 'abc', v: 2 },
{ k: '奈良', v: 3 },
{ k: '奈良先端', v: 4 },
{ k: '奈良先端科学技術大学院大学', v: 5 }
];
var trie = doublearray.builder().build(words);
Browser example
var words = [
{ k: 'a', v: 1 },
{ k: 'abc', v: 2 },
{ k: '奈良', v: 3 },
{ k: '奈良先端', v: 4 },
{ k: '奈良先端科学技術大学院大学', v: 5 }
];
var trie = doublearray.builder().build(words);
Method chaining
var trie = doublearray
.builder()
.append('a', 1)
.append('abc', 2)
.append('奈良', 3)
.append('奈良先端', 4)
.append('奈良先端科学技術大学院大学', 5)
.build();
trie.contain('a'); // -> true
trie.lookup('abc'); // -> 2
trie.commonPrefixSearch('奈良先端科学技術大学院大学');
// -> [ { v: 3, k: '奈良' },
// { v: 4, k: '奈良先端' },
// { v: 5, k: '奈良先端科学技術大学院大学' } ]
Get BASE or CHECK buffer as Int32Array of typed array
var base_buffer = trie.bc.getBaseBuffer();
var check_buffer = trie.bc.getCheckBuffer();
Load and create a new DoubleArray object from original buffers
var loaded_trie = doublearray.load(base_buffer, check_buffer);
