PURPOSE

Set user defined data

SYNONYM

None

SYNOPSIS

#include "lianja_api.h"
 
OBJECT_SETDATA(userdata)
 
<input parameters>
void		*userdata;	/* Pointer to a user defined data area	*/
 
<output parameters>
none

DESCRIPTION

The OBJECT_SETDATA() macro is used assign a user defined data area to an instantiated object. This data area can point to any type of data that can be returned with the OBJECT_GETDATA() macro for the life of the instantiated object.

EXAMPLE

The following example sets the data area from the constructor in a class called clsMyClass.

Example Lianja script:

test = newobject("myclass")

Example in 'C' object:

#include "lianja_api.h"
 
/* Define constructor method */
DEFINE_METHOD(clsMyClass, Constructor) 
{
	struct example_data *objectDataArea;
 
	/* Allocate memory for objects objectData area */
	objectDataArea = (struct example_data *) malloc(sizeof(struct example_data));
	if (objectDataArea == NULL) return(-1);
 
	/* Assign the default property values */
	strcpy(objectDataArea->prop_charvalue, "Test API object");
	objectDataArea->prop_numvalue = 15.2827;
	objectDataArea->prop_logvalue = 'F';
	strcpy(objectDataArea->prop_datevalue, DATE_DATE());
	strcpy(objectDataArea->prop_timevalue, DATE_DATETIME());
	strcpy(objectDataArea->prop_currvalue, "15.2827");
	strcpy(objectDataArea->object_name, "APIobject");
	objectDataArea->prop_objvalue = OBJECT_NEW(objectDataArea->object_name,
"exception", 
NULL);
 
	/* Set the object objectData area */
	OBJECT_SETDATA((char *)objectDataArea);
 
	return(0);
}
