Returns a list of values built from the characters of this and the other char sequences with the same index Appends all elements yielded from results of transform function being invoked on each character Returns a Map containing the characters from the given char sequence indexed by the key replacement for that match. Populates and returns the destination mutable map with key-value pairs, Pads the string to the specified length at the end with the specified character or space. Converts the string into a regular expression Regex with the specified single option. Returns the index within this char sequence of the last occurrence of the specified string, Returns the index within this char sequence of the first occurrence of the specified string, Kotlin strings are mostly similar to Java strings but has some new added functionalities. Returns true if this char sequence contains at least one match of the specified regular expression regex. Returns a string containing characters of the original string at specified indices. Returns the first character having the largest value according to the provided comparator or null if there are no characters. The nice thing about standard libraries is that functions from it can be replaced by intrinsics if so desired. }. Returns the smallest value according to the provided comparator Accumulates value starting with initial value and applying operation from left to right or null if the string is not a valid representation of a number. Returns a string having leading whitespace removed. Parses the string as a Short number and returns the result Ensures that this value lies in the specified range minimumValue..maximumValue. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Returns the length of this char sequence. or null if the string is not a valid representation of a number. Correct me if I’m wrong but I don’t think tirmMargin or trimIndent are ever used with dynamic multiline strings. = null, hint: String? where key is provided by the keySelector function applied to each character of the given char sequence Groups values returned by the valueTransform function applied to each character of the original char sequence Returns a string containing all characters except first characters that satisfy the given predicate. Parses the string as an UByte number and returns the result Returns a character at the given index or null if the index is out of bounds of this char sequence. https://eclipse.org/xtend/documentation/203_xtend_expressions.html#templates. the first and the last lines if they are blank (notice difference blank vs empty). Implementations must fulfil the following Strings are story sequences. Kotlin 1.3.40 will actually support intrinsics for these functions, see https://youtrack.jetbrains.com/issue/KT-17755. Returns a list containing successive accumulation values generated by applying operation from left to right Trims leading whitespace characters followed by marginPrefix from every line of a source string and removes The “solution” is in the String.trim... functions that you can use to trim as desired. Kotlin has great support and many contributors in its fast-growing global community. Returns a subsequence of this char sequence. Replaces invalid input sequences with a default character. Returns a Map containing key-value pairs provided by transform function Indicates whether some other object is "equal to" this one. Finds the first occurrence of any of the specified strings in this char sequence, I don’t have real numbers for this but I’d imagine that in most cases a multiline string in a dynamic trimMargin is just a bug and not intended, so maybe changing this is not as bad of a breaking change than it seems. or null if the string is not a valid representation of a number. Returns this char sequence if it's not empty Detects a common minimal indent like it does trimIndent and replaces it with the specified newIndent. See Packages. Splits this char sequence around matches of the given regular expression. Returns true if this char sequence is not empty. Creates a new byte input stream for the string. Splits this char sequence into several char sequences each not exceeding the given size Replace part of string before the last occurrence of given delimiter with the replacement string. Applies the given transform function to each character in the original char sequence while second string contains characters for which predicate yielded false. starting from the specified startIndex and optionally ignoring the case. It may also be possible to translate the dynamic bits of the string into a call that is wrapped in its own trim function that can is given the needed information for correct wrapping by the compiler. Returns the first character matching the given predicate, or null if no such character was found. to current accumulator value and each character with its index in the original char sequence. What more could you want? or we can call the toRegex method on a String: "a Otherwise, returns this string. Returns the index of the last character in the char sequence or -1 if it is empty. I don’t know what would be the best rule the follow when removing this extra spaces, but I am sure it is possible to figure out some solution. or null if the string is not a valid representation of a number. Groups values returned by the valueTransform function applied to each character of the original char sequence where first string contains characters for which predicate yielded true, 私は最近のような、KotlinのStringにInputStreamの内容全体を読み込むためのコードを見た: // input is of type InputStream val baos = ByteArrayOutputStream() input.use { it.copyTo(baos) } val inputAsString = baos.toString() も:それ自動 Returns true if this nullable char sequence is either null or empty or consists solely of whitespace characters. Returns true if this string is equal to the contents of the specified CharSequence, false otherwise. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Returns the longest string suffix such that this char sequence and other char sequence both end with this suffix, Returns a list containing successive accumulation values generated by applying operation from left to right Returns single character, or null if the char sequence is empty or has more than one character. Kotlin val s = """ This is my multi-line string. or null if the string is not a valid representation of a number. to the specified other object, a negative number if it's less than other, or a positive number an each char sequence representing a view over the window of the given size Parses the string as a ULong number and returns the result. Creates a range from this Comparable value to the specified that value. Parses the string as a UShort number and returns the result. implemented as instances of this class. Replace part of string after the last occurrence of given delimiter with the replacement string. Kotlin makes use of double quotes to construct a literal series. Detects indent by marginPrefix as it does trimMargin and replace it with newIndent. Returns the last character matching the given predicate, or null if no such character was found. Accumulates value starting with initial value and applying operation from right to left Returns a string with the first n characters removed. Otherwise returns this string unchanged. Returns a sequence of snapshots of the window of the given size Returns true if this char sequence starts with the specified prefix. Encodes the contents of this string using the specified character set and returns the resulting byte array. Kotlin では main メソッドのためにわざわざクラスを作る必要がありません。 また、 Kotlin では println がメソッドではなくクラスに属さない関数として実装されています。 そのため System.out を書く必要がありません。 関数は static メソッドのようなものなので、 static も書く必要がありません。 And multiline string keeping extra left spaces is just crazy. Have you ever? Splits this char sequence to a sequence of strings around occurrences of the specified delimiters. Returns a lazy Iterable that wraps each character of the original char sequence Finds the index of the last occurrence of any of the specified strings in this char sequence, Maybe something like this would be good enough for you? Uses the provided format as a format string and returns a string obtained by substituting the specified arguments, Returns a new string obtained by replacing each substring of this char sequence that matches the given regular expression Kotlin strings are also immutable in nature means we can not change elements and length of the String. Returns true if a substring of this char sequence starting at the specified offset startIndex starts with the specified prefix. I don’t know what would be the best rule the follow when removing this extra spaces, but I am sure it is possible Doesn't affect a line if it doesn't contain marginPrefix except the first and the last blank lines. using the specified keySelector function to extract a key from each character. Would be very nice to have such a functionality. with the given replacement. Returns a subsequence of this char sequence specified by the given range of indices. among all values produced by selector function applied to each character in the char sequence. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Returns the smallest value among all values produced by selector function Contribute to square/kotlinpoet development by creating an account on GitHub.

Populates and returns the destination mutable map with key-value pairs Converts the string into a regular expression Regex with the default options. Returns the character (Unicode code point) at the specified index. Returns the index within this string of the first occurrence of the specified character, starting from the specified startIndex. Returns true if this nullable char sequence is either null or empty. Returns a string with the last n characters removed. Replace part of string after the first occurrence of given delimiter with the replacement string. All string literals in Kotlin programs, such as "abc", are by the key returned by the given keySelector function applied to the character Parses the string as an Int number and returns the result Kotlin - Split String to Lines - To split string to lines in Kotlin programming, you may use String.lines() function. Returns a string having trailing characters from the chars array removed. Returns true if this char sequence is not empty and contains some characters except of whitespace characters. Parses the string as an UShort number and returns the result taking care not to split surrogate pairs. snapshot is a string. Splits this char sequence to a list of lines delimited by any of the following character sequences: CRLF, LF or CR. Removes the part of a string at a given range. Meaning, string literals such as … 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). String is one of the basic type in any programming languages, including Kotlin. to each character, its index in the original char sequence and current accumulator value that starts with initial value. an each char sequence representing a view over the window of the given size to each character and current accumulator value. to each character and current accumulator value that starts with the first character of this char sequence. Applies the given transform function to each character of the original char sequence In many use cases, the developer will know whether to expect line breaks in the dynamic parts, and can choose accordingly. Returns a new character sequence that is a subsequence of this character sequence, starting from the specified startIndex and optionally ignoring the case. Returns a random character from this char sequence, or null if this char sequence is empty. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Returns true if this CharSequence has Unicode surrogate pair at the specified index. Returns zero if this object is equal If this string ends with the given suffix, returns a copy of this string Returns a list containing only the non-null results of applying the given transform function EditText Multiline
