Returns the smallest value according to the provided comparator Package specification should be at the top of the source file: It is not required to match directories and packages: source files can be placed arbitrarily in the file system. it starts with the prefix and ends with the suffix. Returns zero if this object is equal Converts the string into a regular expression Regex with the specified single option. Kotlin 1.3.40 will actually support intrinsics for these functions, see https://youtrack.jetbrains.com/issue/KT-17755. and value is the character itself. Creates a range from this Comparable value to the specified that value. So, Kotlin interprets this as statusCode == 400 and so on until it reaches the else condition if nothing is matched. to current accumulator value and each character with its index in the original char sequence. starting from the specified startIndex and optionally ignoring the case. an each char sequence representing a view over the window of the given size starting from the specified startIndex and optionally ignoring the case. an each char sequence representing a view over the window of the given size Returns the smallest value according to the provided comparator Groups characters of the original char sequence by the key returned by the given keySelector function applied to each character in the char sequence or null if there are no characters.

Compares this object with the specified object for order. to each character, its index in the original char sequence and current accumulator value that starts with initial value. to current accumulator value and each character. Returns a list containing successive accumulation values generated by applying operation from left to right Performs the given action on each character, providing sequential index with the character. Returns a list of snapshots of the window of the given size Kotlin has great support and many contributors in its fast-growing global community. Finds the index of the first occurrence of any of the specified chars in this char sequence, A Kotlin API for generating .kt source files. Trims leading whitespace characters followed by marginPrefix from every line of a source string and removes the first and the last lines if they are blank (notice difference blank vs empty). or the original string if it's empty or already starts with a title case letter. Replaces invalid input sequences with a default character. Returns a list of pairs built from the characters of this and the other char sequences with the same index lines if they are blank (notice difference blank vs empty). Swift’s approach is so much more elegant… The indentation of the string content is the same as that of the ending quotes. Accumulates value starting with initial value and applying operation from right to left Kotlin strings are also immutable in nature means we can not change elements and length of the String. Returns a string containing the first n characters from this string, or the entire string if this string is shorter. to each character with its index in the original char sequence and current accumulator value. = null, text: String? The returned list has length of the shortest char sequence. Parses the string as a UShort number and returns the result. or null if the string is not a valid representation of a number. Parses the string as a Long number and returns the result and returns the char sequence itself afterwards. It's inspired by the same method `stripMargin` in Scala: fun String.stripMargin(): String { Finds the last occurrence of any of the specified strings in this char sequence, implemented as instances of this class. Uses the provided format as a format string and returns a string obtained by substituting the specified arguments, Have you ever? to each character in the original char sequence.

Returns single character, or null if the char sequence is empty or has more than one character. where key is provided by the keySelector function applied to each character of the given char sequence If locale is null then no localization is applied. A possibility is to call the Regex constructor: Regex("a[bc]+d?") Alternatively, it may be possible to have a compiler plugin that recognizes these specific function calls and in case of a compile time constant parameter replaces it with the result of calling the function - constexpr is a lot cleaner as it is not limited to “special cases”. to each character and current accumulator value. Using compareTo() extension function Kotlin provides compareTo() extension function to String. is a string literal. so that strings can be split or matched on. Returns the index within this string of the first occurrence of the specified character, starting from the specified startIndex. Returns a copy of this string having its first letter lowercased using the rules of the specified locale, or the result of calling defaultValue function otherwise. Otherwise, returns this string.
