- the last regex matcher
- Since:
- 1.0
-
sleep
public static void sleep(java.lang.Object self, long milliseconds)
Sleep for so many milliseconds, even if interrupted.- Parameters:
self
- placeholder variable used by Groovy categories; ignored for default static methodsmilliseconds
- the number of milliseconds to sleep- Since:

-
parse
public static java.util.Date parse(java.util.Date self, java.lang.String format, java.lang.String input) throws java.text.ParseException
Parse a String into a Date instance using the given pattern. This convenience method acts as a wrapper forSimpleDateFormat
.Note that a new SimpleDateFormat instance is created for every invocation of this method (for thread safety).
- Parameters:
self
- placeholder variable used by Groovy categories; ignored for default static methodsformat
- pattern used to parse the input string.input
- String to be parsed to create the date instance- Returns:
- a new Date instance representing the parsed input string
- Throws:
java.text.ParseException
- if there is a parse error- Since:
- 1.5.7
- See Also:
DateFormat.parse(java.lang.String)
-
parse
public static java.util.Date parse(java.util.Date self, java.lang.String format, java.lang.String input, java.util.TimeZone zone) throws java.text.ParseException
Parse a String into a Date instance using the given pattern and TimeZone. This convenience method acts as a wrapper forSimpleDateFormat
.Note that a new SimpleDateFormat instance is created for every invocation of this method (for thread safety).
- Parameters:
self
- placeholder variable used by Groovy categories; ignored for default static methodsformat
- pattern used to parse the input string.input
- String to be parsed to create the date instancezone
- TimeZone to use when parsing- Returns:
- a new Date instance representing the parsed input string
- Throws:
java.text.ParseException
- if there is a parse error- Since:
- 2.4.1
- See Also:
DateFormat.parse(java.lang.String)
-
parseToStringDate
public static java.util.Date parseToStringDate(java.util.Date self, java.lang.String dateToString) throws java.text.ParseException
Parse a String matching the pattern EEE MMM dd HH:mm:ss zzz yyyy containing US-locale-constants only (e.g. Sat for Saturdays). Such a string is generated by the toString method ofDate
Note that a new SimpleDateFormat instance is created for every invocation of this method (for thread safety).
- Parameters:
self
- placeholder variable used by Groovy categories; ignored for default static methodsdateToString
- String to be parsed to create the date instance. Must match the pattern EEE MMM dd HH:mm:ss zzz yyyy with US-locale symbols- Returns:
- a new Date instance representing the parsed input string
- Throws:
java.text.ParseException
- if there is a parse error
-
getBundle
public static java.util.ResourceBundle getBundle(java.util.ResourceBundle self, java.lang.String bundleName)
Works exactly like ResourceBundle.getBundle(String). This is needed because the java method depends on a particular stack configuration that is not guaranteed in Groovy when calling the Java method.- Parameters:
self
- placeholder variable used by Groovy categories; ignored for default static methodsbundleName
- the name of the bundle.- Returns:
- the resource bundle
- Since:
- 1.6.0
- See Also:
ResourceBundle.getBundle(java.lang.String)
-
getBundle
public static java.util.ResourceBundle getBundle(java.util.ResourceBundle self, java.lang.String bundleName, java.util.Locale locale)
Works exactly like ResourceBundle.getBundle(String, Locale). This is needed because the java method depends on a particular stack configuration that is not guaranteed in Groovy when calling the Java method.- Parameters:
self
- placeholder variable used by Groovy categories; ignored for default static methodsbundleName
- the name of the bundle.locale
- the specific locale- Returns:
- the resource bundle
- Since:
- 1.6.0
- See Also:
ResourceBundle.getBundle(java.lang.String, java.util.Locale)

createTempDir
public static java.io.File createTempDir(java.io.File self) throws java.io.IOException
- Throws:
java.io.IOException
-
createTempDir
public static java.io.File createTempDir(java.io.File self, java.lang.String prefix, java.lang.String suffix) throws java.io.IOException
- Throws:
java.io.IOException

currentTimeSeconds
public static long currentTimeSeconds(java.lang.System self)
Get the current time in seconds- Parameters:
self
- placeholder variable used by Groovy categories; ignored for default static methods- Returns:
