InvokeRemoteMethod

Description

Used in PowerBuilder marshaler native classes to call remote
methods.

Syntax

InvokeRemoteMethod(IPB_Session *session, pbproxyobject obj, LPCTSTR methodDesc, PBCallInfo *ci)

1	InvokeRemoteMethod(IPB_Session session, pbproxyobject obj, LPCTSTR methodDesc, PBCallInfo ci)

Argument	Description
session	This IPB session
obj	The proxy object for the remote object
methodDesc	An arbitrary string stored as an alias name for the remote method in the proxy, for example: function int foo(int a) alias “This is a method in remote BizTalk”
ci	The parameters and return value setting for the call

Return value

PBXRESULT.PBX_OK if the call succeeded.

Examples

This example shows a header file for a sample marshaler
class:

#include "sampleinclude.h"
#include &lt;pbext.h&gt;

class SampleMarshaler : public IPBX_Marshaler
{
private:
string d_mystring;
long d_mylong;

private:
void myMethod(string arg1);

public:
SampleMarshaler(
string myString,
long mylong
);
~SampleMarshaler();

virtual PBXRESULT InvokeRemoteMethod
(
IPB_Session*	session,
pbproxyObject obj,
LPCTSTR				methodDesc,
PBCallInfo*		ci
);

virtual pbulong
GetModuleHandle();
virtual void Destroy();
};

#include "sampleinclude.h"

#include <pbext.h>

class SampleMarshaler : public IPBX_Marshaler

{

private:

string d_mystring;

long d_mylong;

private:

void myMethod(string arg1);

public:

SampleMarshaler(

string myString,

long mylong

);

~SampleMarshaler();

virtual PBXRESULT InvokeRemoteMethod

(

IPB_Session* session,

pbproxyObject obj,

LPCTSTR methodDesc,

PBCallInfo* ci

);

virtual pbulong

GetModuleHandle();

virtual void Destroy();

};

The associated C++ implementation file contains code like
this:

PBXRESULT SampleMarshaler::InvokeRemoteMethod
(
IPB_Session* 	session,
pbproxyObject	obj,
LPCTSTR				methodDesc,
PBCallInfo*		ci
)
{
// method invocation
}

PBXRESULT SampleMarshaler::InvokeRemoteMethod

(

IPB_Session* session,

pbproxyObject obj,

LPCTSTR methodDesc,

PBCallInfo* ci

)

{

// method invocation

}

Usage

You must implement this method in the marshaler native
class.
