Interface: Bytes
rules.
Type representing a sequence of bytes.
Byte literals are specified using ab declaration prefix followed by bytes represented as a sequence of characters, two-place hexadecimal values (for example,b'\x0F', notb'\xF'), or three-place octal values (for example,b'\000', notb'\0'). Character sequences are interpreted as UTF-8 encoded strings.
// These are all equal to decimal 42.b'*'b'\x2A'b'\052'// These are all equivalentb'€' // 3-byte UTF-8 encoded stringb'\342\202\254'b'\xE2\x82\xAC'
Functions for the Bytes type are provided to aid comparison of byte sequences represented as Base64url- and hexadecimal-encoded strings.
Methods
size
size() returns rules.Integer
Returns the number of bytes in a Bytes sequence.
- Returns
non-nullrules.Integerthe number of bytes.
Example
b'\xFF\xFF'.size() == 2b'a'.size() == 1b'€'.size() == 3 // 3-byte UTF-8 encoded stringtoBase64
toBase64() returns rules.String
Returns the Base64-encoded string corresponding to the provided Bytes sequence.
Base64 encoding is performed per thebase64url specification.
- Returns
non-nullrules.Stringa Base64-encoded string.
Example
b'\xFB\xEF\xBE'.toBase64() == '----'toHexString
toHexString() returns rules.String
Returns the hexadecimal-encoded string corresponding to the provided Bytes sequence.
- Returns
non-nullrules.Stringa hexadecimal-encoded string.
Example
b'\x2A'.toHexString() == '2A'b'**'.toHexString() == '2A2A'b'€'.toHexString() == 'E282AC'Except as otherwise noted, the content of this page is licensed under theCreative Commons Attribution 4.0 License, and code samples are licensed under theApache 2.0 License.
