Superx++ Lexicon: attr statement

attr

Purpose The attr statement is used to define an XML attribute within the main part of a Superx++ program or within a method.

Format attr({object name}) {attribute name};
attr({object name}) {attribute name} = {attribute value};

{object name} the name of the node/object to which the attribute will be applied

{attribute name} the name of the attribute

{attribute value} (optional) the initial value of the attribute

What an Attribute defined in an Object looks like in Run-Time Memory

Let us consider an attribute defined in an object, MyEmployee, called status whose value is current. This attribute will be rendered in the run-time memory as follows:
<xppRAM>
<MyEmployee status="current" />
</xppRAM>
where xppRAM is the memory object.

Example #1 attr(MyEmployee) status = "current";
Defines an attribute called status for the MyEmployee object and sets its initial value to current.

Example #2 attr(MyEmployee) status = MyCompany.GetStatus(id = MyEmployee.EmployeeID);
Defines an attribute status on the MyEmployee object and sets its initial value to the return value of the GetStatus method invoked on the MyCompany object.
