Interface AlignmentItem

A single step in an alignment trace.

For an AlignOp.Insertion, refIndex is -1 and refToken is empty. For an AlignOp.Deletion, recIndex is -1 and recToken is empty. For AlignOp.Match and AlignOp.Substitution, both indices and tokens are populated.

Indices refer to positions in the post-normalization token vectors; see TextAligner.referenceTokens.

interface AlignmentItem {
    op: AlignOp;
    refIndex: number;
    recIndex: number;
    refToken: string;
    recToken: string;
}
