Class StringConfigSource

java.lang.Object
  com.tomgibara.pronto.config.source.StringConfigSource

All Implemented Interfaces:

ConfigSource

public class StringConfigSource
extends java.lang.Object
implements ConfigSource

Instances of this class convert a single string into a set of properties as follows: 1) The string is split at each semicolon. 2) Each component is split at a colon into a key and a value. 3) Each key-value pair is trimmed and added to the map This encoding should be superficially familiar to those familiar with CSS style properties. Note that there are no mechanisms for escaping colons and semicolons. Keys may not be duplicated.
