    If it does match, we get the matching string back:
```
     assert "10292" == "New York, NY 10292-0098".find(/\d{5}/)
```
    If we have capture groups in our expression, we still get back the full match
```
     assert "10292-0098" == "New York, NY 10292-0098".find(/(\d{5})-?(\d{4})/)
```
    Parameters:
    
    regex - the capturing regex
    
    Returns:
    
    a String containing the matched portion, or null if the regex doesn't match

    String#find(java.util.regex.Pattern)
  - public String find(CharSequence regex, 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:
    
    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
    
    Since:
    
    1.8.2
    
    See Also:
    
    String#find(java.util.regex.Pattern, groovy.lang.Closure)
  - public String find(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 null == "New York, NY".find(~/\d{5}/)
```
    If it does match, we get the matching string back:
```
     assert "10292" == "New York, NY 10292-0098".find(~/\d{5}/)
```
    If we have capture groups in our expression, the groups are ignored and we get back the full match:
```
     assert "10292-0098" == "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/)
```
    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:
    
    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
    
    See Also:
    
    String#find(java.util.regex.Pattern)
  - public String find(Pattern pattern, 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 null == "New York, NY".find(~/\d{5}/) { match -> return "-$match-"}
```
    If it does match and we don't have any capture groups in our regex, there is a single parameter on the closure that the match gets passed to:
```
     assert "-10292-" == "New York, NY 10292-0098".find(~/\d{5}/) { match -> return "-$match-"}
```
    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 "10292" == "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
     }
```
    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 "10292" == "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { match, zip, plusFour ->
         assert array[0] == "10292-0098"
         assert array[1] == "10292"
         assert array[2] == "0098"
         return array[1]
     }
```
    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 "2339999" == "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"
     }
```
    Parameters:
    
    pattern - the compiled regex Pattern
    
    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
    
    Since:
    
    1.8.2
    
    See Also:
    
    String#find(java.util.regex.Pattern, groovy.lang.Closure)
  - public List findAll(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 expected == "One Fish, Two Fish, Red Fish, Blue Fish".findAll(/(\w*) Fish/)
```
    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:
    
    regex - the capturing regex CharSequence
    
    Returns:

    CharSequence#findAll(Pattern)
  - public List findAll(CharSequence regex, Closure closure)
    
    Finds all occurrences of a regular expression string within a CharSequence. Any matches are passed to the specified closure. The closure is expected to have the full match in the first parameter. If there are any capture groups, they will be placed in subsequent parameters.
    If there are no matches, the closure will not be called, and an empty List will be returned.
    For example, if the regex doesn't match, it returns an empty list:
```
assert [] == "foo".findAll(/(\w*) Fish/) { match, firstWord -> return firstWord }
```
    Any regular expression matches are passed to the closure, if there are no capture groups, there will be one parameter for the match:
```
assert ["couldn't", "wouldn't"] == "I could not, would not, with a fox.".findAll(/.ould/) { match -> "${match}n't"}
```
    If there are capture groups, the first parameter will be the match followed by one parameter for each capture group:
```
def orig = "There's a Wocket in my Pocket"
assert ["W > Wocket", "P > Pocket"] == orig.findAll(/(.)ocket/) { match, firstLetter -> "$firstLetter > $match" }
```
    Parameters:
    
    regex - the capturing regex CharSequence
    
    closure - will be passed the full match plus each of the capturing groups (if any)
    
    Returns:
    
    a List containing all results from calling the closure with each full match (and potentially capturing groups) of the regex within the CharSequence, an empty list will be returned if there are no matches

    See Also:
    
    CharSequence#findAll(Pattern, groovy.lang.Closure)
  - public List findAll(Pattern pattern)
    
    Returns a (possibly empty) list of all occurrences of a regular expression (in Pattern format) found within a CharSequence.
    For example, if the pattern 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 expected == "One Fish, Two Fish, Red Fish, Blue Fish".findAll(~/(\w*) Fish/)
```
    Parameters:
    
    pattern - the compiled regex Pattern
    
    Returns:
    
    a List containing all full matches of the Pattern within the CharSequence, an empty list will be returned if there are no matches

    If there are no matches, the closure will not be called, and an empty List will be returned.
    For example, if the pattern doesn't match, it returns an empty list:
```
assert [] == "foo".findAll(~/(\w*) Fish/) { match, firstWord -> return firstWord }
```
    Any regular expression matches are passed to the closure, if there are no capture groups, there will be one parameter for the match:

  - public String tr(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:
    
    sourceSet - the set of characters to translate from
    
    replacementSet - the set of replacement characters
    
    Returns:
    
    The resulting translated String
