Method Details

__construct() public method

Use $startNode and $endNode parameters if you don't want to use the default start and end nodes. $name must uniquely identify the workflow within the system.
public __construct ( string $name, ezcWorkflowNodeStart $startNode = null, ezcWorkflowNodeEnd $endNode = null, ezcWorkflowNodeFinally $finallyNode = null )
$name string The name of the workflow.
$startNode ezcWorkflowNodeStart The start node of the workflow.
$endNode ezcWorkflowNodeEnd The default end node of the workflow.
$finallyNode ezcWorkflowNodeFinally The start of a node sequence that is executed when a workflow execution is cancelled.

__get() public method

Property read access.
public __get ( string $propertyName ) : mixed
$propertyName string Name of the property.
return mixed Value of the property or null.

__isset() public method

$propertyName string Name of the property.
return boolean True is the property is set, otherwise false.

__set() public method

Property write access.
public __set ( string $propertyName, mixed $val )
$propertyName string Name of the property.
$val mixed The value for the property.

accept() public method

Overridden implementation of accept() calls accept on the start node.
public accept ( ezcWorkflowVisitor $visitor )
$visitor ezcWorkflowVisitor

$className must be the name of a class implementing the ezcWorkflowVariableHandler interface.
public addVariableHandler ( string $variableName, string $className )
$variableName string
$className string

count() public method

Returns the number of nodes of this workflow.
public count ( ) : integer
return integer

getVariableHandlers() public method

The format of the returned array is array( 'variableName' => ezcWorkflowVariableHandler )
public getVariableHandlers ( ) : array
return array

hasSubWorkflows() public method

Returns true when the workflow has sub workflows (ie. when it contains ezcWorkflowNodeSubWorkflow nodes) and false otherwise.
public hasSubWorkflows ( ) : boolean
return boolean true when the workflow has sub workflows, false otherwise.

isInteractive() public method

Returns true when the workflow requires user interaction (ie. when it contains ezcWorkflowNodeInput nodes) and false otherwise.
public isInteractive ( ) : boolean
return boolean true when the workflow is interactive, false otherwise.

removeVariableHandler() public method

Returns false if no handler was set for $variableName.
public removeVariableHandler ( string $variableName ) : boolean
$variableName string
return boolean

reset() public method

public reset ( )

setVariableHandlers() public method

The format of $variableHandlers is array( 'variableName' => ezcWorkflowVariableHandler )
public setVariableHandlers ( array $variableHandlers )
