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.

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 matchassert "New York, NY 10292-0098".find(/(\d{5})-?(\d{4})/) == "10292-0098"
- Parameters:
self
- a CharSequenceregex

self
- a CharSequenceregex
- the capturing regex CharSequenceclosure
- 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

-
find
public static java.lang.String find(java.lang.CharSequence self, java.util.regex.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 CharSequencepattern
- the compiled regex Pattern- Returns:
- a String containing the matched portion, or null if the regex pattern doesn't match
- Since:
- 1.8.2
-
find
public static java.lang.String find(java.lang.CharSequence self, java.util.regex.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
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:->
return "-$match-"} == nullassert "New York, NY 10292-0098".find(~/\d{5}/) { match
If we have capture groups in our expression, our closure has one parameter for the match, followed by one for each of the capture groups:->
return "-$match-"} == "-10292-"assert "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { match, zip, plusFour
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 match == "10292-0098" assert zip == "10292" assert plusFour == "0098" return zip } == "10292"assert "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { array
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 array[0] == "10292-0098" assert array[1] == "10292" assert array[2] == "0098" return array[1] } == "10292"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 CharSequencepattern
- the compiled regex Patternclosure
- 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

replace
public 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:
self
- a CharSequencereplacements

replace
public static java.lang.String replace(java.lang.CharSequence self, int capacity, java.util.Map<java.lang.CharSequence,java.lang.CharSequence> replacements)
Replaces all occurrences of replacement CharSequences (supplied via a map) within a provided CharSequence with control over the internally created StringBuilder's capacity. 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 CharSequencecapacity
- an optimization parameter, set to size after replacements or a little larger to avoid resizing overheadsreplacements
- a map of before (key) and after (value) pairs processed in the natural order of the map- Returns:

tr
public static java.lang.String tr(java.lang.CharSequence self, java.lang.CharSequence sourceSet, java.lang.CharSequence replacementSet) throws java.lang.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 translatedsourceSet
- the set of characters to translate fromreplacementSet
- the set of replacement characters- Returns:
- The resulting translated String
- Throws:
java.lang.ClassNotFoundException
