Primitive type string
The primitive type of strings of characters.
Known direct subtypes
Predicates
| charAt | Returns a one-character string containing the character in the receiver at the given index (which ranges from 0 through length minus one) |
| indexOf | Returns all the offsets at which the given string occurs in the receiver |
| indexOf | Returns the index of n’th occurrence of the given string within receiver, starting at the given offset |
| isLowercase | Holds when the receiver contains no upper-case letters |
| isUppercase | Holds when the receiver contains no lower-case letters |
| length | Returns the length of the receiver (in UTF-16 code units) |
| matches | Holds when the receiver matches the pattern. Patterns are matched by case sensitive string matching, and there are two wildcards: _ matches a single character, and % matches any sequence of characters. To match the actual characters _ or % in the pattern, they must be escaped using backslashes. For example, |
| prefix | Returns the substring of the receiver ending at the given offset |
| regexpCapture | When the given regexp matches the entire receiver, returns the substring matched by the given capture group |
| regexpFind | Returns a substring of the receiver which matches the given regexp. Also returns the offset within the receiver at which the match occurred (occurrenceOffset), and the number of matches which occur at smaller offsets (occurrenceIndex) |
| regexpMatch | Holds when the given regexp matches the entire receiver |
| regexpReplaceAll | Returns a copy of the receiver with every substring which matches the given regexp is replaced by the replacement |
| replaceAll | Returns a copy of the receiver with all occurrences of the target replaced by the replacement |
| splitAt | Returns all of the substrings obtained by splitting the receiver at every occurrence of the argument |
| splitAt | Returns the n’th substring obtained by splitting the receiver at every occurrence of the argument |
| substring | Returns the substring of the receiver which starts and ends at the given indices |
| suffix | Returns the substring of the receiver starting at the given offset |
| toDate | Returns the date, if any, obtained by parsing the receiver |
| toFloat | Returns the floating point number, if any, obtained by parsing the receiver |
| toInt | Returns the integer, if any, obtained by parsing the receiver |
| toLowerCase | Returns a copy of the receiver with all uppercase characters replaced by lowercase ones |
| toString | Returns the receiver |
| toUpperCase | Returns a copy of the receiver with all lowercase characters replaced by uppercase ones |
| trim | Returns a copy of the receiver with all whitespace removed from the beginning and end of the string (where whitespace is defined as unicode codepoints ‘\u0000’ through ‘\u0020’ inclusive) |
