Usage

From source file:jetx.ext.common.StringMethods.java

/**
 * <p>Swaps the case of a String changing upper and title case to
 * lower case, and lower case to upper case.</p>
 *
 * <ul>/*from   w  w  w  .  ja v a 2s  . co m*/
 *  <li>Upper case character converts to Lower case</li>
 *  <li>Title case character converts to Lower case</li>
 *  <li>Lower case character converts to Upper case</li>
 * </ul>
 *
 * <p>For a word based algorithm, see {@link org.apache.commons.lang3.text.WordUtils#swapCase(String)}.
 * A {@code null} input String returns {@code null}.</p>
 *
 * <pre>
 * StringMethods.swapCase(null)                 = null
 * StringMethods.swapCase("")                   = ""
 * StringMethods.swapCase("The dog has a BONE") = "tHE DOG HAS A bone"
 * </pre>
 *
 * <p>NOTE: This method changed in Lang version 2.0.
 * It no longer performs a word based algorithm.
 * If you only use ASCII, you will notice no change.
 * That functionality is available in org.apache.commons.lang3.text.WordUtils.</p>
 *
 * @param str  the String to swap case, may be null
 * @return the changed String, {@code null} if null String input
