Constructor Details

#initialize(bin) ⇒ Binary

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Creates a new Binary from a String containing raw binary data of unknown encoding. If the string’s encoding is not already ASCII-8BIT, a copy of the string is forced to ASCII-8BIT (that is Ruby’s “binary” format). This means that this binary will have the exact same content, but the string will considered to hold a sequence of bytes in the range 0 to 255.

Parameters:

  • A (String) —

    string with binary data

Class Method Details

.from_base64(str) ⇒ Object

Constructs an instance of Binary from a base64 urlsafe encoded string (RFC 2045).

Parameters:

  • A (String) —

    string with RFC 2045 compliant encoded binary

# File 'lib/puppet/pops/types/p_binary_type.rb', line 27

def self.from_base64(str)
  new(Base64.decode64(str))
end

.from_base64_strict(str) ⇒ Object

Constructs an instance of Binary from a base64 strict encoded string (RFC 4648) Where correct padding must be used and line breaks causes an error to be raised.

Parameters:

  • A (String) —

    string with RFC 4648 compliant encoded binary

end

.from_base64_urlsafe(str) ⇒ Object

Constructs an instance of Binary from a base64 encoded string (RFC4648 with “URL and Filename Safe Alphabet” (That is with ‘-’ instead of ‘+’, and ‘_’ instead of ‘/’).

end

.from_binary_string(bin) ⇒ Object

Creates a new Binary from a String containing binary data. If the string’s encoding is not already ASCII-8BIT, a copy of the string is force encoded as ASCII-8BIT (that is Ruby’s “binary” format). This means that this binary will have the exact same content, but the string will considered to hold a sequence of bytes in the range 0 to 255.

The given string will be frozen as a side effect if it is in ASCII-8BIT encoding. If this is not wanted, a copy should be given to this method.

Parameters:

  • A (String) —

    string with binary data

end

.from_string(encoded_string) ⇒ Puppet::Pops::Types::PBinaryType::Binary

Creates a new Binary from a String containing text/binary in its given encoding. If the string’s encoding is not already UTF-8, the string is first transcoded to UTF-8. This means that this binary will have the UTF-8 byte representation of the original string. For this to be valid, the encoding used in the given string must be valid. The validity of the given string is therefore asserted.

The given string will be frozen as a side effect if it is in ASCII-8BIT encoding. If this is not wanted, a copy should be given to this method.

Parameters:

  • A (String) —

    string with valid content in its given encoding

Returns:
