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, `"anythingstring%".matches("%string\\%")` holds.
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)
