Class NamedReferenceTransition

java.lang.Object

ca.phon.fsa.FSATransition<IPAElement>

ca.phon.phonex.PhonexTransition

ca.phon.phonex.NamedReferenceTransition

All Implemented Interfaces:

Cloneable

public class NamedReferenceTransition
extends PhonexTransition

Transition for named references in phonex expressions. (e.g., \{1}, \{C}). The group reference may be negated (e.g., \{^1}, \{^C}). When used in aligned expressions, the group reference may be a group which is not currently matched. In this case, the fsa will initially follow the transition and defer the match until the information is available. This is possible because aligned expressions will never increase the tape position and execute on a different tape consisting of the aligned elements.
