Detailed Description

Utility class which collects utility functions for delegates.

XCube_DelegateUtils\call("Delegate Name"[, function args...]);
XCube_DelegateUtils\raiseEvent("Event Name"[, function params...]);
$string = XCube_DelegateUtils\applyStringFilter("Filter Name", $string, [, option params...]);

Member Function Documentation

_compareCallback()

static _compareCallback ( $callback1, $callback2 )

static

Parameters

$callback1	callback
$callback2	callback

Returns

bool

Attention

Only XCube_Delegate, XCube_DelegateManager and sub-classes of them should use this method.

applyStringFilter()

static applyStringFilter ( )

static

Parameters

1st	string - Delegate Name
2nd	string
3rd	and more - Optional function parameters

Returns

string

raiseEvent()

static raiseEvent ( )

static

[Static] Utility method for calling event-delegates.

Parameters

1st	Delegate Name
2nd	and more : Delegate function parameters

Returns

bool

Deprecated

Use call()

This method is a shortcut for calling delegates without actual delegate objects. If there is not the delegate specified by the 1st parameter, the delegate will be made right now. Therefore, this method is helpful for events.

Note

XCube_DelegateUtils::raiseEvent("Module.A.Exception.Null");

The upper code equals the following code;

{
    $local =new XCube_Delegate();
    $local->register("Module.A.Exception.Null");
    $local->call();
  }

Attention

Only event-owners should use this method. Outside program never calls other's events. This is a kind of XCube_Delegate rules. There is the following code;

ClassA::check()
{
  if ($this->mThing == null)
     XCube_DelegateUtils::raiseEvent("Module.A.Exception.Null");
  }

In this case, another class never calls the event.

//
// NEVER writes the following code;
//
$obj = new ClassA();
if ($obj->mThing == null)
     XCube_DelegateUtils::raiseEvent("Module.A.Exception.Null");

Other classes may call only ClassA::check();
