kotlin multiline string

Returns a List containing all characters. Returns index of the last character matching the given predicate, or -1 if the char sequence does not contain such character. Otherwise returns this string unchanged. Ensures that this value is not greater than the specified maximumValue. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. to current accumulator value and each character. or null if the string is not a valid representation of a number. implemented as instances of this class. Returns a new MutableList filled with all characters of this char sequence. Returns a sequence of results of applying the given transform function to Returns a random character from this char sequence using the specified source of randomness. sliding along this char sequence with the given step, where each Finds the index of the first occurrence of any of the specified chars in this char sequence, and applies the given transform function to an each. or null if the string is not a valid representation of a number. Appends all characters matching the given predicate to the given destination. Returns a string with characters in reversed order. This seems like an ideal candidate for a compiler (not JVM) intrinsic. Contribute to square/kotlinpoet development by creating an account on GitHub. applied to each character and returns a map where each group key is associated with a list of corresponding characters. among all values produced by selector function applied to each character in the char sequence. Splits this char sequence to a list of lines delimited by any of the following character sequences: CRLF, LF or CR. Splits the original string into pair of strings, Returns the first character matching the given predicate, or null if no such character was found. There are two convenient functions in stdlib for stripping margin from multiline strings: trimMargin and trimIndent. Detects a common minimal indent like it does trimIndent and replaces it with the specified newIndent. String is one of the basic type in any programming languages, including Kotlin. Returns a Map containing the characters from the given char sequence indexed by the key by the key returned by the given keySelector function applied to the character Kotlinの標準入力の方法を2つご紹介しました。 1つ目はmain関数の引数に渡す方法、 2つ目はreadLine関数を使う方法でした。 readLine関数はJavaのBufferedReaderを内部的に使用しており、 String?型が返ってくることを想定して入力の Returns the first character yielding the largest value of the given function or null if there are no characters.

Returns the index within this char sequence of the last occurrence of the specified string, Have you ever? or null if the string is not a valid representation of a number. 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. Splits this char sequence into a sequence of strings each not exceeding the given size. to each character and current accumulator value that starts with initial value. Would be very nice to have such a functionality. Returns a substring specified by the given range of indices. Returns a list of values built from the characters of this and the other char sequences with the same index Using compareTo() extension function Kotlin provides compareTo() extension function to String. requirements: Returns the character of this string at the specified index.

Removes the part of a string at the given range. Returns a string having leading characters from the chars array removed. Xtend has solved this really nicely: Replace part of string before the last occurrence of given delimiter with the replacement string. Ensures that this value lies in the specified range. Populates and returns the destination mutable map with key-value pairs for each character of the given char sequence, The String class in Kotlin contains strings of characters. starting from the specified startIndex and optionally ignoring the case. an each char sequence representing a view over the window of the given size or null if the string is not a valid representation of a number. Kotlin 1.3.40 will actually support intrinsics for these functions, see https://youtrack.jetbrains.com/issue/KT-17755. Accumulates value starting with initial value and applying operation from right to left It’s useful, yes, but it can’t be done if it doesn’t work properly.

Finds the first occurrence of any of the specified strings in this char sequence, starting from the specified startIndex and optionally ignoring the case. Returns the largest value among all values produced by selector function and value is the character itself. It would probably be best implemented in an optimistic fashion (assuming that it doesn’t need to wrap). 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. Returns true if at least one character matches the given predicate.

Appends all elements yielded from results of transform function being invoked on each character of original char sequence, to the given destination. Prepends indent to every line of the original string. provided by transform function applied to each character of the given char sequence. So if you’re debugging this code, and you want to log the exact query string, or copy paste it into an sqlite3 (or your SQL client of choice) to play around with it, it’s going to be ugly.

Returns the largest value according to the provided comparator using the specified locale. Parses the string as a signed Byte number and returns the result using the specified locale. among all values produced by selector function applied to each character in the char sequence 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. String s = """ This is a very long string which needs to wrap across multiple lines because otherwise my code is unreadable. to current accumulator value and each character. Fortunately, Kotlin has this handled as well. Returns the single character matching the given predicate, or null if character was not found or more than one character was found. Returns a random character from this char sequence using the specified source of randomness, or null if this char sequence is empty. 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 The returned list has length of the shortest char sequence. Returns a string with the last n characters removed. I agree that there should be an option to do the trimming at runtime. Returns true if this char sequence ends with the specified character. Otherwise, returns this string. Returns the length of this char sequence. Parses the string as an ULong number and returns the result where key is the character itself and value is provided by the valueSelector function applied to that key. using the default locale. Accumulates value starting with the last character and applying operation from right to left if and only if it starts with and ends with the delimiter. Returns a string having trailing whitespace removed. starting from the specified startIndex and optionally ignoring the case. Otherwise returns this string unchanged. A Kotlin API for generating .kt source files. Returns true if all characters match the given predicate. Returns true if this CharSequence has Unicode surrogate pair at the specified index. Returns a character at the given index or null if the index is out of bounds of this char sequence. Performs the given action on each character. 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”. The problem with that approach is the trimming is done at run time. Returns true if this char sequence contains the specified other sequence of characters as a substring. Returns a string containing characters of the original string at the specified range of indices. If locale is null then no localization is applied. Returns this char sequence if it is not empty and doesn't consist solely of whitespace characters, the trimming can’t be done at compile time, because Kotlin doesn’t know if name contains line breaks. Regular expressions are instances of the kotlin.text.Regex class.
