WordSegmentFinder
public
class
WordSegmentFinder
extends SegmentFinder
Implementation of SegmentFinder
using words as the text segment. Word boundaries are
found using WordIterator
. Whitespace characters are excluded, so they are not included in
any text segments.
For example, the text "Hello, World!" would be subdivided into four text segments: "Hello",
",", "World", "!". The space character does not belong to any text segments.
