void setMeta<T>(
  1. T value
)

Sets the metadata of type T to the specified value. Nodes can have arbitrary annotations on them set via setMeta and obtained via meta. This mechanism is used to, for instance, attach variable scopes to a subtree.

Implementation

void setMeta<T>(T value) {
  _metadata[T] = value;
}
