Sets the string value. Decodes and replaces this string's value as if it was a base64-encoded String. Encodes and replaces this string's value according to base64-encoding. Appends the provided string to current value. Inserts the provided string at the beginning. Overwrites the string value from its beginning with the given string. If the provided string is longer than current value, then the resulting value equals the provided string. If the provided string is shorter than current value, then the resulting value ends with the trailing characters from current value. Cuts heading and trailing characters of current string. Truncate the string to a given length. Replaces all occurrences of a string by another string. Sets the string value with a randmly generated string of a given size. Creates a new pattern (aka regular expression) for further search and capture of elements in the current string. Use "match" to trigger the next matching attempt, or "slice" to split the string into substrings, considering the pattern as a separator. Patterns are based on Java's java.util.regex package. http://docs.oracle.com/javase/1.6.0/docs/api/java/util/regex/Pattern.html Resets the pattern matching process at the beginning of the string, using the previously set pattern. Finds the next match of current pattern, optionally skipping a number of matches. When necessary and only if matching is successful, use "capture" to extract elements from the matching substring. Sets a variable with the substring that matched current pattern, as stated in the regular expression by a capture group. This substring will then be available through expression ${handler_id:my_variable}. Replaces all substrings that matches the current pattern with the given string. Slices the current value into substrings, using the current pattern as a separator (see "setPattern"). Resulting slices are available through variables slice#1 ... slice#n, or slice for current slice when using "nextSlice". Variable slice++ gives next slice. Variable clice# gives the number of slices. Give control help. Replaces this string's current value with its digest (aka hash) according to the chosen algorithm. Decodes current string considered as URL-encoded. Encodes current string accorgin to the URL encoding rules. True if current string contains the given string, false otherwise. False if current string contains the given string, true otherwise. True if current string equals the given string, false otherwise. True if current string differs from the given string, false otherwise. True if current string equals the given string, whatever letters are upper case or lower case, false otherwise. True if current string differs from the given string, whatever letters are upper case or lower case, false otherwise. True if at least one more string slice is available through a subsequent call to nextSlice or reference to variable slice++. True if no more string slice is available through a subsequent call to nextSlice or reference to variable slice++. True if current string is empty, false otherwise. True if current string is not empty, false otherwise. True if current string length equals the given value, false otherwise. True if current string length differs from the given value, false otherwise. True if current string length is strictly greater than the given value, false otherwise. True if current string length is greater than, or equals, the given value, false otherwise. True if current string length is strictly less than the given value, false otherwise. True if current string length is less than, or equals, the given value, false otherwise. True if the last pattern matching was successful, false otherwise. False if the last pattern matching was successful, true otherwise. True if current string is greater than the given string, with regard to the alphabetical ordering, false otherwise. True if current string is less than the given string, with regard to the alphabetical ordering, false otherwise. True if current string is greater than, or equals the given string, with regard to the alphabetical ordering, false otherwise. True if current string is less than, or equals the given string, with regard to the alphabetical ordering, false otherwise.
