CLRInterop::isInitialized Method
Determines whether a value has been assigned to the specified CLRObject instance.
Syntax
client server public static boolean isInitialized(CLRObject clrObject)
Run On
Called
Parameters
- clrObject
Type: CLRObject Class
The CLRObject instance to evaluate.
Return Value
Type: boolean
true if a value has been assigned to the CLRObject instance; otherwise, false.
Remarks
When CLR types are declared in X++, they have a value of null Nothing nullptr unit a null reference (Nothing in Visual Basic) , regardless of the value of the actual CLR type that is wrapped by the X++ object. The type can be instantiated so that a value can be assigned to it (by using the new method). Or you can use the CLRInterop::null assignment.
Invoking CLR methods on uninitialized CLR types will cause a run-time error.
Examples
The following example initializes the CLR object and calls the CLRInterop::isInitialized method to evaluate whether the object was initialized.
static void Job4(Args _args)
{
System.String s;
// This syntax is the same as calling:
// ClrObject s = ClrInterop::getObjectForAnyType(“initialized”);
System.String s1 = "initialized";
// This will print "false".
print CLRInterop::isInitialized(s);
// This will print "true".
print CLRInterop::isInitialized(s1);
pause;
