(async) new UnicodeSet(pattern) → {Promise.<RangeGroup>}
This does not need to be called with new. Parses and evaluates a UnicodeSet string as a RangeGroup. This is an async function as it will lazily load the unicode character name and property data as it is needed.

Methods
(static) evaluate(node) → {Promise.<RangeGroup>}
Takes an AST as generated from UnicodeSet.parse and evaluates as a RangeGroup
| Name | Type | Description |
|---|---|---|
node | object | AST node to evaluate |
- Type:
- Promise.<RangeGroup>
(static) lazyEvaluate(node) → {Promise.<LazyGroup>}
Takes an AST as generated from UnicodeSet.parse and evaluates it into a lazily evaluated group
| Name | Type | Description |
|---|---|---|
node | object | AST node to evaluate |
- Type:
- Promise.<LazyGroup>
(static) parse(pattern) → {Promise.<Node>}
Parse a UnicodeSet pattern into an abstract syntax tree (AST). Some trivial transformations are performed on the tree to reduce groups, combine invert/complement, and combine nodes. The parsing is async, as it lazily loads unicode data as it becomes needed.
