Workflow::ezcWorkflowNodeVariableMul

Class ezcWorkflowNodeVariableMul

Multiplies a workflow variable with another variable or a constant value.

An object of the ezcWorkflowNodeVariableMul class multiplies a specified workflow variable with a given operand, either a constant or the value of another workflow variable.

This example will multiply the contents of the workflow variable 'wfVar' by five and put the result in 'wfVar'.

  1.  <?php
  2.  $mul = new ezcWorkflowNodeVariableMul(
  3.    array( 'name' => 'wfVar', 'operand' => 5 )
  4.  );
  5.  ?>

If the operand is a string, the value of the workflow variable identified by that string is used.
