XML::Compile::SOAP::Operation(3) base-class for possible interactions

INHERITANCE

 XML::Compile::SOAP::Operation is extended by
   XML::Compile::SOAP11::Operation
   XML::Compile::SOAP12::Operation

SYNOPSIS


# created by XML::Compile::WSDL11
my $op = $wsdl->operation('GetStockPrices');

DESCRIPTION

These objects are created by XML::Compile::WSDL11, grouping information about a certain specific message interchange between a client and a server.

METHODS

Constructors

XML::Compile::SOAP::Operation->new(%options)
 -Option     --Default
  action       undef
  endpoints    []
  kind         <required>
  name         <required>
  schemas      <required>
  server_type  undef
  transport    'HTTP'
action => STRING
Some string which is refering to the action which is taken. For SOAP protocols, this defines the soapAction header.
endpoints => ADDRESS|ARRAY
Where to contact the server.
kind => 'one-way'|...
This returns the type of operation this is. There are four kinds, which are returned as strings "one-way", "request-response", "sollicit-response", and "notification". The latter two are initiated by a server, the former two by a client.
name => STRING
schemas => XML::Compile::Cache
server_type => NAME
Most server implementations show some problems. Also, servers may produce responses using their own namespaces (like for error codes). When you know which server you are talking to, the quirks of the specific server type can be loaded. Read more in the ``Supported servers'' in XML::Compile::SOAP.
transport => URI|'HTTP'
"HTTP" is short for "http://schemas.xmlsoap.org/soap/http/", which is a constant to indicate that transport should use the HyperText Transfer Protocol.

Accessors

$obj->bindingName()
$obj->clientClass()
Returns the class name which implements the Client side for this protocol.
$obj->endPoints()
Returns the list of alternative URLs for the end-point, which should be defined within the service's port declaration.
$obj->kind()
$obj->longName()
[3.06] prefix the service name before the operation name, to make it really unique. A "#" is used as separator.
$obj->name()
$obj->portName()
$obj->schemas()
$obj->serverClass()
Returns the class name which implements the Server side for this protocol.
$obj->serviceName()
$obj->soapAction()
Used for the "soapAction" header in HTTP transport, for routing messages through firewalls.
$obj->version()
$obj->wsaAction('INPUT'|'OUTPUT')
Only available when "XML::Compile::SOAP::WSA" is loaded. It specifies the name of the operation in the WSA header. With "INPUT", it is the Action to be used with a message sent to the server (input to the server). The "OUTPUT" is used by the server in its message back.

Handlers

$obj->compileClient(%options)
Returns one CODE reference which handles the conversion from a perl data-structure into a request message, the transmission of the request, the receipt of the answer, and the decoding of that answer into a Perl data-structure.
$obj->compileHandler(%options)
Returns a code reference which translates in incoming XML message into Perl a data-structure, then calls the callback. The result of the callback is encoded from Perl into XML and returned. 

 -Option  --Default
  callback  <required>
callback => CODE
$obj->compileTransporter(%options)
Create the transporter code for a certain specific target. 

 -Option        --Default
  endpoint        <from WSDL>
  server          undef
  transport_hook  undef
  transporter     <created>
endpoint => URI|ARRAY-of-URI
Overrule the destination address(es).
server => URI-HOST
Overrule only the server part in the endpoint, not the whole endpoint. This could be a string like "username:password@myhost:4711". Only used when no explicit "endpoint" is provided.
transport_hook => CODE
Passed to XML::Compile::Transport::compileClient(hook). Can be used to create off-line tests and last resort work-arounds. See the DETAILs chapter in the XML::Compile::Transport manual page.
transporter => CODE|XML::Compile::Transport-object
The routine which will be used to exchange the data with the server. This code is created by an XML::Compile::Transport::compileClient() extension.

By default, a transporter compatible to the protocol is created. However, in most cases you want to reuse one (HTTP1.1) connection to a server.

[3.14] You may provide a XML::Compile::Transport object as well. Its compileClient() will be called for you.

Helpers

$obj->explain($wsdl, $format, $direction, %options)
Dump an annotated structure showing how the operation works, helping developers to understand the schema. $format is "PERL" or "XML".

The $direction is "INPUT", it will return the message which the client sends to the server (input for the server). The "OUTPUT" message is sent as response by the server.

$obj->parsedWSDL(%options)
[2.29] For some purposes, it is useful to get access to the parsed WSDL structure.

Be aware that the structure returned is consided ``internal'' and strongly influenced by behavior of XML::Compile; backwards compatibility will not be maintained at all cost.

You can use XML::Compile::Schema::template() format "TREE" to get more details about the element types mentioned in this structure.

example: 

  use Data::Dumper;
  $Data::Dumper::Indent    = 1;
  $Data::Dumper::Quotekeys = 0;
  print Dumper $op->parsedWSDL;
