Tree

class Tree(val type: NodeType, children: List<Any>, val positions: List<Int>, val length: Int, propValues: Map<Int, Any?> = emptyMap())

A syntax tree. Immutable, constructed by parsers. Children may be Tree or TreeBuffer instances.

Constructors

constructor(type: NodeType, children: List<Any>, positions: List<Int>, length: Int, propValues: Map<Int, Any?> = emptyMap())

The top node of this tree (wraps the tree as a SyntaxNode).

fun balance(config: BalanceConfig = BalanceConfig()): Tree

Balance a tree, making sure no children arrays grow too large for optimal performance.

Create a cursor that starts at the top of the tree.

fun cursorAt(pos: Int, side: Int = 0, mode: Int = 0): TreeCursor

Create a cursor positioned at a given position.

Iterate over all nodes in the tree within a range.

fun <T> prop(prop: NodeProp<T>): T?

Look up a per-node prop value.

fun resolve(pos: Int, side: Int = 0): SyntaxNode

Resolve to the innermost node at position pos.

Like resolve, but enters overlay-mounted trees.

Returns a NodeIterator pointing at the innermost node at pos, with its NodeIterator.next linking to enclosing nodes up to the top.
