constructor

new UnicodeTrieBuilder(initialValue?, errorValue?): UnicodeTrieBuilder
Parameters
- Optional initialValue: number
- Optional errorValue: number
Returns UnicodeTrieBuilder

Methods

freeze

freeze(): UnicodeTrie
Returns UnicodeTrie
The compacted and frozen data as a new UnicodeTrie instance.

get

get(codePoint, fromLSCP?): number
Parameters
- codePoint: number
  Code point to lookup.
- Optional fromLSCP: boolean
  Is this a lead surrogate code point.
Returns number

set

set(codePoint, value): this
Parameters
- codePoint: number
  Code point to set.
- value: number
  New value at code point.
Returns this

setRange

setRange(start, end, value, overwrite?): this
Parameters
- start: number
  Start code point.
- end: number
  End code point.
- value: number
  Value to set.
- Optional overwrite: boolean
  Overwrite existing values.
Returns this

toBuffer

toBuffer(): Buffer
Generates a Node Buffer containing the serialized and compressed trie.

Note: This only works on Node. Use toUint8Array otherwise.

uint32_t highStart; uint32_t errorValue; uint32_t uncompressedDataLength; uint8_t trieData[dataLength];

Returns Buffer
A Node Buffer.

toUint8Array

toUint8Array(): Uint8Array
Generates a packed Uint8Array containing the serialized and compressed trie.

Note: This only works on Node. Use toUint8Array otherwise.

uint32_t highStart; uint32_t errorValue; uint32_t uncompressedDataLength; uint8_t trieData[dataLength];

Returns Uint8Array
A packed Uint8Array.
