Class TierAligner

java.lang.Object

ca.phon.session.alignment.TierAligner

public final class TierAligner
extends Object

Helper class for aligning two tiers of a record. Tier values are first filtered using tier alignment rules and then left-aligned. The result is a list of tuples where each tuple contains an element from the top tier and an element from the bottom tier. If one tier has more elements than the other, nulls are used to fill in the gaps (i.e., 'indels.')
