 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 areverse()method forString.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.

replacepublic static java.lang.String replace(java.lang.CharSequence self, java.util.Map<java.lang.CharSequence,java.lang.CharSequence> replacements)Replaces all occurrences of replacement CharSequences (supplied via a map) within a provided CharSequence.assert 'foobar'.replace(f:'b', foo:'bar') == 'boobar' assert 'foobar'.replace(foo:'bar', f:'b') == 'barbar' def replacements = [foo:'bar', f:'b', b: 'f', bar:'boo'] assert 'foobar'.replace(replacements) == 'barfar' - Parameters:

This method uses a StringBuilder internally. Java auto-expands a StringBuilder's capacity if needed. In rare circumstances, the overhead involved with repeatedly expanding the StringBuilder may become significant. If you have measured the performance of your application and found this to be a significant bottleneck, use this variant to have complete control over the internally created StringBuilder's capacity.assert 'foobar'.replace(9, [r:'rbaz']) == 'foobarbaz' assert 'foobar'.replace(1, [fooba:'']) == 'r' - Parameters:
- self- a CharSequence
- capacity- an optimization parameter, set to size after replacements or a little larger to avoid resizing overheads

- Returns:
- a String formed from the provided CharSequence after performing all of the replacements

trpublic static java.lang.String tr(java.lang.CharSequence self, java.lang.CharSequence sourceSet, java.lang.CharSequence replacementSet) throws java.lang.ClassNotFoundExceptionTranslates 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
- Throws:
- java.lang.ClassNotFoundException
