The Example
of the Perform action shows how to
invoke a method using the Perform action. Notice the
following facts about these examples:
In Example 1, the Perform action calls the update() method on
the variable $importedVar$. Notice that:
The entire method call is enclosed in dollar signs ($).
In the context of a method call, the variable name itself (importedVar)
is not enclosed in dollar signs ($).
A variable passed as a parameter to a method must be enclosed
in dollar signs ($) as usual ($str$).
A string passed as a parameter to a method must be enclosed in
single quotes as usual ('Application').
In Example 2, the Perform action calls a static method.
In Example 3, the Perform action calls the close() method belonging
to the class to which the variable belongs, such as java.io.FileInputStream.
In Example 4, the Perform action calls the createZipEntry() method
belonging to the class to which the variable belongs, such as java.util.zip.ZipInputStream.
In Example 5, the Perform action calls the clear() method belonging
to the class to which the variable belongs, such as java.util.Hashtable.

of the Perform action
<actions>
<!-- Example 1 -->
<perform value="$importedVar.update( 5, 'Application', $str$)$" />
<!-- Example 2 -->
<perform value="$MyClass.myInit('all')$" />
<!-- Example 3 -->
<perform value="$fip.close()$" />
<!-- Example 4 -->
<perform value="$zis.createZipEntry( $name$ )$" />
<!-- Example 5 -->
<perform value="$ht.clear()$" />
</actions>
