## Class StringGroovyMethods

- java.lang.Object
- - org.codehaus.groovy.runtime.DefaultGroovyMethodsSupport
  - - 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.

      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

                                    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)

          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
      See Also:
        `find(String, java.util.regex.Pattern)`

    - #### find

          public static String find(CharSequence self,
                                    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 "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)
      Returns:
        a String containing the result of calling the closure (calling toString() if needed), or null if the regex pattern doesn't match

      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:

    - #### matchesPartially

          public static boolean matchesPartially(Matcher matcher)

      Given a matcher that matches a string against a pattern, this method returns true when the string matches the pattern or if a longer string, could match the pattern. For example:

               def emailPattern = /\w+@\w+\.\w{2,}/

               def matcher = "john@doe" =~ emailPattern
               assert matcher.matchesPartially()

               matcher = "john@doe.com" =~ emailPattern
               assert matcher.matchesPartially()

               matcher = "john@@" =~ emailPattern
               assert !matcher.matchesPartially()

      Parameters:
        `matcher` - the Matcher
      Returns:
        true if more input to the String could make the matcher match the associated pattern, false otherwise.

          public static String padLeft(CharSequence self,
                                       Number numberOfChars,
                                       CharSequence padding)

      Pad a CharSequence to a minimum length specified by `numberOfChars`, adding the supplied padding CharSequence as many times as needed to the left. If the CharSequence is already the same size or bigger than the target `numberOfChars`, then the toString() of the original CharSequence is returned. An example:

           println 'Numbers:'
           [1, 10, 100, 1000].each{ println it.toString().padLeft(5, '*') }
           [2, 20, 200, 2000].each{ println it.toString().padLeft(5, '*_') }

      will produce output like:

           Numbers:
           ****1
           ***10
           **100
           *1000
           *_*_2
           *_*20
           *_200
           *2000

      Parameters:
        `self` - a CharSequence object
        `numberOfChars` - the total minimum number of characters of the resulting CharSequence
        `padding` - the characters used for padding
      Returns:
        the CharSequence padded to the left as a String

      Pad a CharSequence to a minimum length specified by `numberOfChars` by adding the space character to the right as many times as needed. If the CharSequence is already the same size or bigger than the target `numberOfChars`, then the toString() of the original CharSequence is returned. An example:

           ['A', 'BB', 'CCC', 'DDDD'].each{ println it.padRight(5) + it.size() }

      will produce output like:

      Replaces all occurrences of a captured group by the result of calling a closure on that text.

      Examples:

               assert "hello world".replaceAll("(o)") { it[0].toUpperCase() } == "hellO wOrld"

               assert "foobar-FooBar-".replaceAll("(([fF][oO]{2})[bB]ar)", { Object[] it -> it[0].toUpperCase() }) == "FOOBAR-FOOBAR-"

               // Here,
               //   it[0] is the global string of the matched group
               //   it[1] is the first string in the matched group
               //   it[2] is the second string in the matched group

               assert "foobar-FooBar-".replaceAll("(([fF][oO]{2})[bB]ar)", { x, y, z -> z.toUpperCase() }) == "FOO-FOO-"

               //   y is the first string in the matched group
               //   z is the second string in the matched group

      Note that unlike String.replaceAll(String regex, String replacement), where the replacement string treats '$' and '\' specially (for group substitution), the result of the closure is converted to a string and that value is used literally for the replacement.
      Parameters:
        `self` - a CharSequence
        `regex` - the capturing regex
        `closure` - the closure to apply on each captured group

      Replaces all substrings of a CharSequence that match the given compiled regular expression with the given replacement.

      Note that backslashes (`\`) and dollar signs (`$`) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string; see `Matcher.replaceAll(java.lang.String)`. Use `Matcher.quoteReplacement(java.lang.String)` to suppress the special meaning of these characters, if desired.

           assert "foo".replaceAll('o', 'X') == 'fXX'

      Parameters:
        `self` - the CharSequence that is to be matched
        `pattern` - the regex Pattern to which the CharSequence of interest is to be matched
        `replacement` - the CharSequence to be substituted for the first match

    - #### tr

          public static String tr(CharSequence self,
                                  CharSequence sourceSet,
                                  CharSequence replacementSet)
                           throws ClassNotFoundException

      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`
