StringGroovyMethods (groovy 3.0.4 API)

org.codehaus.groovy.runtime.StringGroovyMethods

```
public class StringGroovyMethods
extends DefaultGroovyMethodsSupport
```
This class defines new groovy methods which appear on String-related JDK classes (String, CharSequence, Matcher) inside the Groovy environment. Static methods are used with the first parameter being the destination class, e.g. public static String reverse(String self) provides a reverse() method for String.
NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.

  - public static String find(CharSequence self, CharSequence regex)
    
    Finds the first occurrence of a regular expression String within a String. If the regex doesn't match, null will be returned.
    For example, if the regex doesn't match the result is null:
```
     assert "New York, NY".find(/\d{5}/) == null
 
```
    If it does match, we get the matching string back:
```
      assert "New York, NY 10292-0098".find(/\d{5}/) == "10292"
 
```
    If we have capture groups in our expression, we still get back the full match
```
      assert "New York, NY 10292-0098".find(/(\d{5})-?(\d{4})/) == "10292-0098"
 
```
    Parameters:
    self - a CharSequence
    regex - the capturing regex
    Returns:
    a String containing the matched portion, or null if the regex doesn't match
    See Also:
    find(CharSequence, java.util.regex.Pattern)
    Since:
    1.8.2
  - public static String find(CharSequence self, CharSequence regex, @ClosureParams(value=FromString.class, options={"java.util.List","java.lang.String[]"}) Closure closure)
    
    Returns the result of calling a closure with the first occurrence of a regular expression found within a CharSequence. If the regex doesn't match, the closure will not be called and find will return null.
    Parameters:
    self - a CharSequence
    regex - the capturing regex CharSequence
    closure - the closure that will be passed the full match, plus each of the capturing groups (if any)
    Returns:
    a String containing the result of calling the closure (calling toString() if needed), or null if the regex pattern doesn't match
    See Also:
    find(CharSequence, java.util.regex.Pattern, groovy.lang.Closure)
    Since:
    1.8.2
  - public static String find(CharSequence self, Pattern pattern)
    
    Finds the first occurrence of a compiled regular expression Pattern within a String. If the pattern doesn't match, null will be returned.
    For example, if the pattern doesn't match the result is null:
```
     assert "New York, NY".find(~/\d{5}/) == null
 
```
    If it does match, we get the matching string back:
```
      assert "New York, NY 10292-0098".find(~/\d{5}/) == "10292"
 
```
    If we have capture groups in our expression, the groups are ignored and we get back the full match:
```
      assert "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) == "10292-0098"
 
```
    If you need to work with capture groups, then use the closure version of this method or use Groovy's matcher operators or use eachMatch.
    Parameters:
    self - a CharSequence
    pattern - the compiled regex Pattern
    Returns:
    a String containing the matched portion, or null if the regex pattern doesn't match
    Since:
    1.8.2
  - public static String find(CharSequence self, Pattern pattern, @ClosureParams(value=FromString.class, options={"java.util.List","java.lang.String[]"}) Closure closure)
    
    Returns the result of calling a closure with the first occurrence of a compiled regular expression found within a String. If the regex doesn't match, the closure will not be called and find will return null.
    For example, if the pattern doesn't match, the result is null:
```
     assert "New York, NY".find(~/\d{5}/) { match -> return "-$match-"} == null
 
```
    If it does match and we don't have any capture groups in our regex, there is a single parameter on the closure that the match gets passed to:
```
      assert "New York, NY 10292-0098".find(~/\d{5}/) { match -> return "-$match-"} == "-10292-"
 
```
    If we have capture groups in our expression, our closure has one parameter for the match, followed by one for each of the capture groups:
```
      assert "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { match, zip, plusFour ->
          assert match == "10292-0098"
          assert zip == "10292"
          assert plusFour == "0098"
          return zip
      } == "10292"
 
```
    If we have capture groups in our expression, and our closure has one parameter, the closure will be passed an array with the first element corresponding to the whole match, followed by an element for each of the capture groups:
```
      assert "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { array ->
          assert array[0] == "10292-0098"
          assert array[1] == "10292"
          assert array[2] == "0098"
          return array[1]
      } == "10292"
 
```
    If a capture group is optional, and doesn't match, then the corresponding value for that capture group passed to the closure will be null as illustrated here:
```
      assert "adsf 233-9999 adsf".find(~/(\d{3})?-?(\d{3})-(\d{4})/) { match, areaCode, exchange, stationNumber ->
          assert "233-9999" == match
          assert null == areaCode
          assert "233" == exchange
          assert "9999" == stationNumber
          return "$exchange$stationNumber"
      } == "2339999"
 
```
    Parameters:
    self - a CharSequence
    pattern - the compiled regex Pattern
    closure - the closure that will be passed the full match, plus each of the capturing groups (if any)

    a String containing the result of calling the closure (calling toString() if needed), or null if the regex pattern doesn't match
    Since:
    1.8.2
  - public static List<String> findAll(CharSequence self, CharSequence regex)
    
    Returns a (possibly empty) list of all occurrences of a regular expression (provided as a CharSequence) found within a CharSequence.
    For example, if the regex doesn't match, it returns an empty list:
```
 assert "foo".findAll(/(\w*) Fish/) == []
 
```
    Any regular expression matches are returned in a list, and all regex capture groupings are ignored, only the full match is returned:
```
 def expected = ["One Fish", "Two Fish", "Red Fish", "Blue Fish"]
 assert "One Fish, Two Fish, Red Fish, Blue Fish".findAll(/(\w*) Fish/) == expected

 assert "foo".replaceFirst('o', 'X') == 'fXo'
 
```
    Parameters:
    self - the CharSequence that is to be matched
    pattern - the regex Pattern to which the CharSequence of interest is to be matched

 assert "/tmp:/usr".tokenize(pathSep) == ["/tmp", "/usr"]
 
```
    Parameters:
    self - a CharSequence
    delimiter - the delimiter
    Returns:
    a List of tokens
    See Also:
    StringTokenizer.StringTokenizer
    Since:
    1.8.2
  - @SuppressWarnings("unchecked") public static List<String> tokenize(CharSequence self, CharSequence delimiters)
    
    Tokenize a CharSequence based on the given CharSequence. Each character in the CharSequence is a separate delimiter.
    Parameters:
    self - a CharSequence
    delimiters - the delimiters
    Returns:
    a List of tokens
    See Also:
    StringTokenizer.StringTokenizer
    Since:
    1.8.2
  - public static String tr(CharSequence self, CharSequence sourceSet, CharSequence replacementSet)
    
    Translates a CharSequence by replacing characters from the sourceSet with characters from replacementSet. If the first character from sourceSet appears in the CharSequence, it will be replaced with the first character from replacementSet. If the second character from sourceSet appears in the CharSequence, it will be replaced with the second character from replacementSet. and so on for all provided replacement characters.
    Here is an example which converts the vowels in a word from lower to uppercase:
```
 assert 'hello'.tr('aeiou', 'AEIOU') == 'hEllO'
 
```
    A character range using regex-style syntax can also be used, e.g. here is an example which converts a word from lower to uppercase:
```
 assert 'hello'.tr('a-z', 'A-Z') == 'HELLO'
 
```
    Hyphens at the start or end of sourceSet or replacementSet are treated as normal hyphens and are not considered to be part of a range specification. Similarly, a hyphen immediately after an earlier range is treated as a normal hyphen. So, '-x', 'x-' have no ranges while 'a-c-e' has the range 'a-c' plus the '-' character plus the 'e' character.
    Unlike the unix tr command, Groovy's tr command supports reverse ranges, e.g.:
```
 assert 'hello'.tr('z-a', 'Z-A') == 'HELLO'
 
```
    If replacementSet is smaller than sourceSet, then the last character from replacementSet is used as the replacement for all remaining source characters as shown here:
```
 assert 'Hello World!'.tr('a-z', 'A') == 'HAAAA WAAAA!'
 
```
    If sourceSet contains repeated characters, the last specified replacement is used as shown here:
```
 assert 'Hello World!'.tr('lloo', '1234') == 'He224 W4r2d!'
 
```
    The functionality provided by tr can be achieved using regular expressions but tr provides a much more compact notation and efficient implementation for certain scenarios.
    Parameters:
    self - the CharSequence that is to be translated
    sourceSet - the set of characters to translate from
    replacementSet - the set of replacement characters
    Returns:
    The resulting translated String
    See Also:
    StringUtil.tr
    Since:
    1.8.2
  - public static String uncapitalize(CharSequence self)
    
    Convenience method to uncapitalize the first letter of a CharSequence (typically the first letter of a word). Example usage:
```
 assert 'H'.uncapitalize() == 'h'
 assert 'Hello'.uncapitalize() == 'hello'
 assert 'Hello world'.uncapitalize() == 'hello world'
 assert 'Hello World'.uncapitalize() == 'hello World'
 assert 'hello world' ==
     'Hello World'.split(' ').collect{ it.uncapitalize() }.join(' ')
 
```
    Parameters:
    self - The CharSequence to uncapitalize
    Returns:
    A String containing the uncapitalized toString() of the CharSequence
    Since:
    2.4.8
  - public static String unexpand(CharSequence self)
    
    Replaces sequences of whitespaces with tabs using tabStops of size 8.
    Parameters:
    self - A CharSequence to unexpand
    Returns:
    an unexpanded String
    Since:
    1.8.2
  - public static String unexpand(CharSequence self, int tabStop)
    
    Replaces sequences of whitespaces with tabs.
    Parameters:
    self - A CharSequence to unexpand
    tabStop - The number of spaces a tab represents
    Returns:
    an unexpanded String
    Since:
    1.8.2
  - public static String unexpandLine(CharSequence self, int tabStop)
    
    Replaces sequences of whitespaces with tabs within a line.
    Parameters:
    self - A line to unexpand
    tabStop - The number of spaces a tab represents
    Returns:
    an unexpanded String
    Since:
    1.8.2
