• func getStringFromAscii() -> String

  Converts ASCII/Latin-1 encoded array to String. Fast alternative to getStringFromUtf8 if the content is ASCII/Latin-1 only. Unlike the UTF-8 function this function maps every byte to a character in the array. Multibyte sequences will not be interpreted correctly. For parsing user input always use getStringFromUtf8. This is the inverse of String/toAsciiBuffer().

• func getStringFromUtf16() -> String

  Converts UTF-16 encoded array to String. If the BOM is missing, system endianness is assumed. Returns empty string if source array is not valid UTF-16 string. This is the inverse of String/toUtf16Buffer().

• func getStringFromUtf32() -> String

  Converts UTF-32 encoded array to String. System endianness is assumed. Returns empty string if source array is not valid UTF-32 string. This is the inverse of String/toUtf32Buffer().

• func getStringFromUtf8() -> String

  Converts UTF-8 encoded array to String. Slower than getStringFromAscii but supports UTF-8 encoded data. Use this function if you are unsure about the source of the data. For user input this function should always be preferred. Returns empty string if source array is not valid UTF-8 string. This is the inverse of String/toUtf8Buffer().

• func getStringFromWchar() -> String

  Converts wide character (wchar_t, UTF-16 on Windows, UTF-32 on other platforms) encoded array to String. Returns empty string if source array is not valid wide string. This is the inverse of String/toWcharBuffer().

• func has(value: Int64) -> Bool

  Returns true if the array contains value.

• func hasEncodedVar(byteOffset: Int64, allowObjects: Bool) -> Bool

  Returns true if a valid Variant value can be decoded at the byteOffset. Returns false otherwise or when the value is Object-derived and allowObjects is false.

• func hexEncode() -> String

  Returns a hexadecimal representation of this array as a String.

• func index(after: Int) -> Int
• func index(before: Int) -> Int
• func insert(atIndex: Int64, value: Int64) -> Int64

  Inserts a new element at a given position in the array. The position must be valid, or at the end of the array (idx == size()).

  Appends an element at the end of the array.

• func removeAt(index: Int64)

  Removes an element from the array by index.

• func resize(newSize: Int64) -> Int64

• func reverse()

  Reverses the order of the elements in the array.

• func rfind(value: Int64, from: Int64) -> Int64

  Searches the array in reverse order. Optionally, a start search index can be passed. If negative, the start index is considered relative to the end of the array.
