Instance Method Summary collapse
-
#read_ber(syntax = nil) ⇒ Object
Nondestructively reads a BER object from this string.
-
#read_ber!(syntax = nil) ⇒ Object
Destructively reads a BER object from the string.
- #reject_empty_ber_arrays ⇒ Object
-
#to_ber(code = 0x04) ⇒ Object
Converts a string to a BER string.
-
#to_ber_application_string(code) ⇒ Object
Creates an application-specific BER string encoded value with the provided syntax code value.
-
#to_ber_bin(code = 0x04) ⇒ Object
Converts a string to a BER string but does not encode to UTF-8 first.
-
#to_ber_contextspecific(code) ⇒ Object
Creates a context-specific BER string encoded value with the provided syntax code value.

# File 'lib/net/ber/core_ext/string.rb', line 62 def read_ber(syntax = nil) StringIO.new(self).read_ber(syntax) end |
#read_ber!(syntax = nil) ⇒ Object
Destructively reads a BER object from the string.

# File 'lib/net/ber/core_ext/string.rb', line 77 def reject_empty_ber_arrays self.gsub(/0\000/n, '') end |
#to_ber(code = 0x04) ⇒ Object
Converts a string to a BER string. Universal octet-strings are tagged with 0x04, but other values are possible depending on the context, so we let the caller give us one.
User code should call either #to_ber_application_string or #to_ber_contextspecific.

#to_ber_application_string(code) ⇒ Object
Creates an application-specific BER string encoded value with the provided syntax code value.

#to_ber_bin(code = 0x04) ⇒ Object
Converts a string to a BER string but does not encode to UTF-8 first. This is required for proper representation of binary data for Microsoft Active Directory
