Package: phing\types\selectors

This is the base class for selectors that can contain other selectors.

This class handles the common description attribute and provides a default implementation for reference handling and checking for circular references that is appropriate for types that can not be nested inside elements of the same type (i.e. patternset but not path)

Properties

boolean
                 $checked= 'true'

inherited

Are we sure we don't hold circular references?

Inherited from: \DataType::$checked

Subclasses are responsible for setting this value to false if we'd need to investigate this condition (usually because a child element has been added that is a subclass of DataType).

           $stk,  $p
          )
        
        :
          void

inherited

Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

Inherited from: \DataType::dieOnCircularReference()

If one is included, throw a BuildException created by circularReference

This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

The general contract of this method is that it shouldn't do anything if checked is true and set it to true on exit.

Name	Type	Description
$stk
$p

          void

inherited

Set the value of the refid attribute.

Inherited from: \DataType::setRefid()

Subclasses may need to check whether any other attributes have been set as well or child elements have been created and thus override this method. if they do they must call parent::setRefid()

Parameters

Name	Type	Description
$r	\Reference

toString(
          
          )
        
        :

inherited

Creates an exception that indicates that refid has to be the only attribute if it is set.

Inherited from: \DataType::tooManyAttributes()

validate(
          
          )
        
        :
          void

This implementation validates the container by calling verifySettings() and then validates each contained selector provided that the selector implements the validate interface.

Ordinarily, this will validate all the elements of a selector container even if the isSelected() method of some elements is never called. This has two effects:

Validation will often occur twice.
Since it is not required that selectors derive from BaseSelector, there could be selectors in the container whose error conditions are not detected if their isSelected() call is never made.

verifySettings(
          
          )
        
        :
          void

inherited

Subclasses can override this method to provide checking of their state. So long as they call validate() from isSelected(), this will be called automatically (unless they override validate()).

Implementations should check for incorrect settings and call setError() as necessary.

Inherited from: \BaseSelector::verifySettings()
