26 * An event protocol parameter class for token delimited textual event protocols that may be specialized by event
27 * protocol plugins that require plugin specific parameters.
29 * <p>The following parameters are defined:
31 * <li>startDelimiterToken: the token string that delimits the start of text blocks that contain events.
32 * <li>endDelimiterToken: the token string that delimits the end of text blocks that contain events, this parameter is
33 * optional and defaults to null.
34 * <li>delimiterAtStart: indicates if the first text block should have a delimiter at the start (true), or whether
35 * processing of the first block should begin at the start of the text (false). The parameter is optional and defaults
