NAME ^

XML::Compile::SOAP::Operation - 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    []
  kin          <required>
  nam          <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.

kin => d

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.

nam => e
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 quircks 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->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

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.

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;
