Returns true iff the read alignment spans a gap and the flanking contigs have in different orientation (according to this alignment).
Returns true iff the read alignment is an back extension, ie. it is an extension and reaches over the back of the reference contig.
Returns true iff the read alignment is an extension, ie. it is a front or back extension.
Returns true iff the read alignment is an front extension, ie. it is an extension and reaches over the front of the reference contig.
Returns true iff the read alignment spans a gap, ie. two alignments of the same read on different reference contigs are involved.
If readAlignment is a gap return true iff the first alignment's contigA.id is lower than the second alignment's; otherwise returns true.
Returns true iff the read alignment spans a gap and the flanking contigs have in the same orientation (according to this alignment).
Returns true iff the read alignment is valid, ie. it is either an extension or gap.
Get the type of the read alignment.
Alignment of a read against the reference. This is either one or two alignment chains which belong to the same read and one or two reference contig(s).
