    • isTrue

      public static boolean isTrue(String value)
      Tests the String 'value': return 'false' if its 'false', '0', or 'no' - else 'true'

      Follow in 'C' tradition of boolean values: false is specific (0), everything else is true;

    • isTrueExplicitly

      public static boolean isTrueExplicitly(Object value, boolean defaultVal)
      Tests the Object 'value': if its null, return default. if its a Boolean, return booleanValue() if its an Integer, return 'false' if its '0' else 'true' if its a String, return isTrueExplicitly((String)value). All other types return 'true'

    • isTrueExplicitly

    • isTrue

      public static boolean isTrue(Object value, boolean defaultVal)
      Tests the Object 'value': if its null, return default. if its a Boolean, return booleanValue() if its an Integer, return 'false' if its '0' else 'true' if its a String, return 'false' if its 'false', 'no', or '0' - else 'true' All other types return 'true'

      public static boolean isTrue(Object value)

    • isFalse

      public static boolean isFalse(String value)
      Tests the String 'value': return 'true' if its 'false', '0', or 'no' - else 'false'

      Follow in 'C' tradition of boolean values: false is specific (0), everything else is true;

      public static boolean isFalseExplicitly(Object value, boolean defaultVal)
      Tests the Object 'value': if its null, return default. if its a Boolean, return !booleanValue() if its an Integer, return 'true' if its '0' else 'false' if its a String, return isFalseExplicitly((String)value). All other types return 'false'

    • isFalseExplicitly

      public static boolean isFalseExplicitly(Object value)

    • isJavaId

      public static boolean isJavaId(String id)

    • split

      public static String[] split(String str, char separatorChar)

      Splits the provided text into an array, separator specified. This is an alternative to using StringTokenizer.

      The separator is not included in the returned String array. Adjacent separators are treated as one separator.

      A null input String returns null.

       StringUtils.split(null, *)         = null
 StringUtils.split("", *)           = []
 StringUtils.split("a.b.c", '.')    = ["a", "b", "c"]
 StringUtils.split("a..b.c", '.')   = ["a", "b", "c"]
 StringUtils.split("a:b:c", '.')    = ["a:b:c"]
 StringUtils.split("a\tb\nc", null) = ["a", "b", "c"]
 StringUtils.split("a b c", ' ')    = ["a", "b", "c"]
      Parameters:
      str - the String to parse, may be null
      separatorChar - the character used as the delimiter, null splits on whitespace
      Returns:
      an array of parsed Strings, null if null String input

      public static int indexOfIgnoreCase(String string, String search)
      Scans the parameter string for the parameter search ignoring case when comparing characters.
      Parameters:
      string -

      Returns:
      -1 if the string was not found or the index of the first matching character

    • replace

      public static final String replace(String name, String oldT, String newT)

      newT - new text to use
      Returns:
      replacement string

    • callStackToString

      public static String callStackToString()
      Get a string containing the stack of the current location. Note This utility is useful in debug scenarios to dump out the call stack.
      Returns:
      String

    • stackToString

      public static String stackToString(Throwable e)
      Get a string containing the stack of the specified exception

      e -
      Returns:

    • getObjectIdentity

      public static String getObjectIdentity(Object obj)
      Mimics the default Object.toString() produces a string of the form: obj.getClass().getName() + "@" + object's hashCode. This method can be used to print the debug message when you want just the short name or if using the toString will cause full expansion of underlying data structures. The returned value can also be used as an identity key.
      Returns:
      obj.getClass().getName() + "@" + Integer.toHexString(System.identityHashCode(obj));
