Returns an iterator over the values of this record.

Usage

From source file:org.sonar.scanner.config.DefaultConfiguration.java

/**
 * In most cases we expect a single record. <br>Having multiple records means the input value was splitted over multiple lines (this is common in Maven).
 * For example:/*from  w ww .j  a v  a2  s  . c o m*/
 * <pre>
 *   &lt;sonar.exclusions&gt;
 *     src/foo,
 *     src/bar,
 *     src/biz
 *   &lt;sonar.exclusions&gt;
 * </pre>
 * In this case records will be merged to form a single list of items. Last item of a record is appended to first item of next record.
 * <p>
 * This is a very curious case, but we try to preserve line break in the middle of an item:
 * <pre>
 *   &lt;sonar.exclusions&gt;
 *     a
 *     b,
 *     c
 *   &lt;sonar.exclusions&gt;
 * </pre>
 * will produce ['a\nb', 'c']
