PURPOSE
A macro to define a class
SYNONYM
None
SYNOPSIS
#include "dbapi.h" DEFINE_CLASS(classname) <input parameters> constant classname; /* Class name */ <output parameters> none
DESCRIPTION
The DEFINE_CLASS() macro is used to define a class that can be accessed from the Recital 4GL. This class needs to be added to the API_SHARED_FUNCTION_TABLE data structure which is loaded dynamically when Recital is started.
EXAMPLE
The following example defines a class called clsMyClass and defines some dispatch methods.
Example Recital program:
// The constructor is called when the object is created test = newobject("myclass") ? type("test")
</code>
Example in 'C' object:
#include "dbapi.h" static struct API_SHARED_FUNCTION_TABLE api_function_table[2] = { {"myclass", "clsMyClass", API_CLASS}, {NULL, NULL, -1} } ; DEFINE_CLASS(clsMyClass) { /* Dispatch factory methods and return */ DISPATCH_FACTORY(); /* Dispatch constructor and return */ DISPATCH_METHOD(clsMyClass, Constructor); /* Dispatch destructor and return */ DISPATCH_METHOD(clsMyClass, Destructor); }
