Nested Phases

Nested Phases

Anchors that have nested anchors, such as
Group
, have nested phases. For example, if a
Group
anchor runs in the main phase of a Parser, a
Marker
anchor that is nested in the
Group
runs in a nested initial phase. The nested initial phase is part of the Parser main phase, but it is before the other anchors in the
Group
.
Another example is a
RepeatingGroup
anchor, which searches for both separators and for nested anchors. In order to identify the nested anchors correctly, it searches for the separators before it searches for the nested anchors.
