CApplicationComponent is the base class for application component classes.

CApplicationComponent implements the basic methods required by IApplicationComponent.

When developing an application component, try to put application component initialization code in the init() method instead of the constructor. This has the advantage that the application component can be customized through application configuration.

Property Details

behaviors property (available since v1.0.2)

public array $behaviors;

the behaviors that should be attached to this component. The behaviors will be attached to the component when init is called. Please refer to CModel::behaviors on how to specify the value of this property.

isInitialized property read-only

public boolean getIsInitialized()

whether this application component has been initialized (i.e., init() is invoked.)

Method Details

getIsInitialized() method

public boolean getIsInitialized()
{return}	boolean	whether this application component has been initialized (i.e., init() is invoked.)

init() method

public void init()

Initializes the application component. This method is required by IApplicationComponent and is invoked by application. If you override this method, make sure to call the parent implementation so that the application component can be marked as initialized.
