* ((<XMLRPC::Base64>))
= XMLRPC::Base64
== Description
This class is necessary for (('xmlrpc4r')) to determine that a string should
be transmitted base64-encoded and not as a raw-string.
You can use (({XMLRPC::Base64})) on the client and server-side as a
parameter and/or return-value.
== Class Methods
--- XMLRPC::Base64.new( str, state = :dec )
Creates a new (({XMLRPC::Base64})) instance with string ((|str|)) as the
internal string. When ((|state|)) is (({:dec})) it assumes that the
string ((|str|)) is not in base64 format (perhaps already decoded),
otherwise if ((|state|)) is (({:enc})) it decodes ((|str|))
and stores it as the internal string.
--- XMLRPC::Base64.decode( str )
Decodes string ((|str|)) with base64 and returns that value.
--- XMLRPC::Base64.encode( str )
Encodes string ((|str|)) with base64 and returns that value.
== Instance Methods
--- XMLRPC::Base64#decoded
Returns the internal string decoded.
--- XMLRPC::Base64#encoded
Returns the internal string encoded with base64.
