SnapshotSeq

Appends a string element to this sequence, if it doesn't already exist in the sequence.

If the string element already exists in this sequence, this method returns itself. If not, this method returns a new MultiSelOptionSeq with the passed value appended to the end of the original MultiSelOptionSeq.

Removes a string element to this sequence, if it already exists in the sequence.

If the string element does not already exist in this sequence, this method returns itself. If the element is contained in this sequence, this method returns a new MultiSelOptionSeq with the passed value removed from the the original MultiSelOptionSeq, leaving any other elements in the same order.

Selects an element by its index in the sequence.

This method invokes apply on the underlying immutable IndexedSeq[String], passing in idx, and returns the result.

The length of this sequence.

This method invokes length on the underlying immutable IndexedSeq[String] and returns the result.

An alternate way to present the result of the snap method of trait Snapshots that puts each variable or expression on its own line.

Here's an example:

scala> snap(a, b, c, d, e, f).lines
res4: String =
a was 1
b was 2
c was 3
d was 4
e was null
f was null

The default way to present the result of the snap method of trait Snapshots.

Here's an example:

scala> snap(a, b, c, d, e, f)
res3: org.scalactic.SnapshotSeq = a was 1, b was 2, c was 3, d was 4, e was null, f was null
