Class StringTokenSet

java.lang.Object

org.osgl.util.StringTokenSet

All Implemented Interfaces:

Iterable<String>, Collection<String>, Set<String>

public class StringTokenSet
extends Object
implements Set<String>

StringTokenSet implement Set based on a list of String tokens separated by SEPARATOR.

Examples:

• "foo,bar" contains "foo" and "bar"
• ",,x,,y" contains three empty string and "x", "y"

This data structure is better to be used in case the string token set are unlikely to change and the number of string tokens are not very big (no bigger than 20)

This data structure is not thread safe
