Workflow::ezcWorkflowNodeInput

Class ezcWorkflowNodeInput

An object of the ezcWorkflowNodeInput class represents an input (from the application) node.

When the node is reached, the workflow engine will suspend the workflow execution if the specified input data is not available (first activation). While the workflow is suspended, the application that embeds the workflow engine may supply the input data and resume the workflow execution (second activation of the input node). Input data is stored in a workflow variable.

Incoming nodes: 1 Outgoing nodes: 1

This example creates a simple workflow that expectes two input variables, once which can be any value and another that can only be an integer between one and ten.

  1.  <?php
  2.  $workflow = new ezcWorkflow( 'Test' );
  3.  
  4.  $input = new ezcWorkflowNodeInput(
  5.    'mixedVar' => new ezcWorkflowConditionIsAnything,
  6.    'intVar'   => new ezcWorkflowConditionAnd(
  7.      array(
  8.        new ezcWorkflowConditionIsInteger,
  9.        new ezcWorkflowConditionIsGreatherThan( 0 )
  10.        new ezcWorkflowConditionIsLessThan( 11 )
  11.      )
  12.    )
  13.  );
  14.  
  15.  $input->addOutNode( $workflow->endNode );
  16.  $workflow->startNode->addOutNode( $input );
  17.  ?>

__construct

ezcWorkflowNodeInput __construct( [mixed $configuration = ''] )

Constructs a new input node.

An input node accepts an array of workflow variables to accept and/or together with a condition on the variable if required.

Each element in the configuration array must be either String: The name of the workflow variable to require. No conditions.

or

  • Key: The name of the workflow variable to require.
  • Value: An object of type ezcWorkflowCondition
Parameters:
Name Type Description
$configuration mixed
