byte_array

type byte_array : iterable<integer>

An array of bytes. This type is immutable.

Since

0.6.0

Constructors

pure constructor(hex: text)

Creates a byte_array from a hexadecimal string.

pure constructor(list: list<integer>)

Creates a byte_array from a list of integers.

Functions

pure function ~~decode~~(): text

pure function empty(): boolean

Returns true if the byte_array is empty, otherwise returns false.

static function from_base64(value: text): byte_array

Creates a byte_array from a Base64 string.

pure static function from_hex(value: text): byte_array

Creates a byte_array from a hexadecimal string.

pure static function from_list(list: list<integer>): byte_array

Creates a byte_array from a list of integers.

pure function join_to_text([separator: text], [prefix: text], [postfix: text], [limit: integer?], [truncated: text], [transform: (integer) -> text]): text

Creates a text from all the elements separated using separator and using the given prefix and postfix if supplied.

If the iterable is large, you can specify a non-negative value of limit, in which case only the first limit of elements will be appended, followed by the truncated text (which defaults to "...").

(alias) pure function ~~len~~(): integer

Returns the number of bytes.

Alias

pure function repeat(n: integer): byte_array

Repeats the byte_array 'n' times.

pure function reversed(): byte_array

Returns a reversed copy of the byte_array.

pure function sha256(): byte_array

Returns the SHA256 digest of the byte_array.

pure function size(): integer

Returns the number of bytes.

pure function sub(start: integer): byte_array

Returns a sub-array of the byte_array from the specified start index.

pure function sub(start: integer, end: integer): byte_array

Returns a sub-array of the byte_array from the specified start index to the end index.

pure function to_base64(): text

Returns a Base64 representation of the byte_array.

pure function to_hex(): text

Returns a hexadecimal representation of the byte_array.

pure function to_list(): list<integer>

Converts the byte_array to a list of integers.

(alias) pure function ~~toList~~(): list<integer>

Converts the byte_array to a list of integers.
