Enclosing class:

SegmentSequence

public static final class SegmentSequence.Builder
extends Object

A builder for creating a composed string or a toSegmentSequence(). It may be a more efficient alternative to StringBuilder because the strings are not copied to a character-based buffer until toString() is called. At that time, the total number of characters needed is known, so a character array can be allocated and used direct to create a string. Using the empty string as the delimiter is particularly useful for that purpose.
