PURPOSE
Assign a name to an instantiated object
SYNONYM
None
SYNOPSIS
#include "lianja_api.h" OBJECT_ASSIGN(objptr, objname) <input parameters> OBJECT objptr; /* Pointer to the object to assign name to */ char *objname; /* Name to assign to the object */ <output parameters> none
DESCRIPTION
The OBJECT_ASSIGN() macro is used to assign a name to an instantiated object. You must assign a name to an object when it is passed as a value to set a property.
EXAMPLE
The following example instantiates an object from a system class EXCEPTION and assigns it to the ObjValue property in a class called clsMyClass.
Example Lianja script:
test = newobject("myclass") // Instantiate an EXCEPTION object and assign it to the property ObjValue test.objvalue=newobject("exception")
Example in 'C' object:
#include "lianja_api.h" /* define set property method */ DEFINE_PROPERTYSET(clsMyClass, ObjValue) { struct example_data *objectData = (struct example_data *)OBJECT_GETDATA(); OBJECT objvalue; int rc = OBJECT_ERROR; if (OBJECT_GETTYPE() == 'O') { objvalue = OBJECT_GETOBJECT(); objectData->prop_objvalue = OBJECT_ASSIGN(objvalue, objectData->object_name); rc = OBJECT_SUCCESS; } return(rc); }
