Filter filters the tree and returns the iterator of nodes that satisfy the given query.

FilterNode evaluates a query and returns a results as a boolean value.

FilterInt evaluates a query and returns a results as an int value.

FilterNode filters the tree and returns a single node that satisfy the given query.

FilterNumber evaluates a query and returns a results as a float64 value.

FilterString evaluates a query and returns a results as a string value.

FilterValue evaluates a query and returns a results as a value.

Iterate function is similar to Next() but returns the `Node`s in a channel.

NewContext creates a new query context.

NewIterator constructs a new Iterator starting from the given `Node` and iterating with the traversal strategy given by the `order` parameter.

LevelOrder (aka breadth-first) traversal.

PositionOrder by node position in the source file.

PostOrder traversal.

PreOrder traversal.

Iterator allows for traversal over a UAST tree.

TreeOrder represents the traversal strategy for UAST trees.
