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="{object name}" name="{attribute name}">
   {attribute value}
<arr>

{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 object="MyEmployee" name="status">current</arr>
Defines an attribute called status for the MyEmployee object and sets its initial value to current.

Example #2 <attr object="MyEmployee" name="status">
   <eval object="MyCompany" member="GetStatus">
      <parm type="int" name="id">
         <eval object="MyEmployee" member="EmployeeID" />
      </parm>
   </eval>
</arr>
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.
