RPC::XML::Function(3) User Contributed Perl DocumentationRPC::XML::Function(3)NAMERPC::XML::Function - Object class for RPC routines that do not check
signatures
SYNOPSIS
require RPC::XML::Function;
...
$method_1 = RPC::XML::Function->new(name => 'system.identity',
code => sub { ... });
$method_2 = RPC::XML::Function->new('/path/to/status.xpl');
DESCRIPTION
The RPC::XML::Function is a class that derives from RPC::XML::Procedure
(see RPC::XML::Procedure), while bypassing all the signature-specific
logic associated with server-side methods in the RPC::XML suite.
By doing this, the encapsulated code becomes responsible for how the
server (and ultimately, the client) interprets returned values. For the
classes that adhere to signatures, the signature includes the expected
type of the returned value. If an object of this class anticipates that
the data may be ambiguous (an intended string being interpreted as an
integer, for example), the code it encapsulates should consider encod-
ing the response with the data-classes documented in RPC::XML prior to
return.
USAGE
Only those routines different from RPC::XML::Procedure are listed:
new(LIST)
The constructor for this class is identical to the super-class ver-
sions, except that it disregards any "signature" keys on the input
list. The return value upon success is a newly-blessed object ref-
erence, otherwise an error message is returned.
signature
Returns "undef" only.
clone
Acts as the parent "clone" method, save that in the absence of any
signature data, the clone is in fact a perfect copy of the origi-
nal.
is_valid
Uses the same validity test, minus the checking of signature data
(tests only for valid "name" and "code" keys).
match_signature
Always returns the string, "scalar".
DIAGNOSTICS
Unless otherwises specified, routines return the object reference
itself upon a successful operation, and an error string (which is not a
blessed reference) upon error.
