Class AbstractWidget

This abstract widget implementation collaborates with a ViewInterface object.

In this collaboration the Widget plays the "view" role and the ViewInterface object the "model" role, where data is stored.

Concrete implementations of an abstract widget specify how the data of the model is rendered into a string.

Methods summary
`public`	# `__construct( Nethgui\View\ViewInterface $view )`
`public`	# `getAttribute( string $attribute, mixed $default = NULL )` Read an attribute value. Read an attribute value. If the attribute has not been set return the given default value. The second argument can also be a callable. In this case, it is invoked only if a default value is needed, and is expected to return that value. The attribute name will be passed as first function argument. Parameters `$attribute` The attribute name `$default` The default value or callable closure/function. Api Implementation of `Nethgui\Renderer\WidgetInterface::getAttribute()`
`public Nethgui\Renderer\WidgetInterface`	# `setAttribute( string $attribute, mixed $value )` Set the given $attribute to $value Set the given $attribute to $value Parameters `$attribute` The attribute name `$value` Any value to be assigned to the attribute Returns `Nethgui\Renderer\WidgetInterface` the current object Api Implementation of `Nethgui\Renderer\WidgetInterface::setAttribute()`
`public boolean`	# `hasAttribute( string $attribute )` Checks if the widget has the given $attribute Checks if the widget has the given $attribute Parameters `$attribute` The attribute name Returns boolean TRUE, if the $attribute has been set to any value Api Implementation of `Nethgui\Renderer\WidgetInterface::hasAttribute()`
`protected static`	# `getInstanceCounter( )`
`protected`	# `prepend( Nethgui\Renderer\WidgetInterface $widget )`
`public Nethgui\Renderer\WidgetInterface`	# `insert( Nethgui\Renderer\WidgetInterface $widget )` Nest $widget into the current object Nest $widget into the current object Parameters `$widget` Another widget to be nested inside the current object Returns `Nethgui\Renderer\WidgetInterface` the current object Api Implementation of `Nethgui\Renderer\WidgetInterface::insert()`
`protected`	# `renderContent( )`
`protected`	# `renderChildren( )`
`protected`	# `getChildren( )`
`protected`	# `hasChildren( )`
`protected`	# `wrapChild( $childOutput )`
`public`	# `__toString( )`
`public string`	# `render( )` Transform the current object in a string value. Transform the current object in a string value. Returns string Api Implementation of `Nethgui\Renderer\WidgetInterface::render()`
`protected`	# `getClientEventTarget( )`
`public Nethgui\Log\LogConsumerInterface`	# `setLog( Nethgui\Log\LogInterface $log )` Change the log attached to the interface implementor Change the log attached to the interface implementor Parameters `$log` Returns `Nethgui\Log\LogConsumerInterface` Api Implementation of `Nethgui\Log\LogConsumerInterface::setLog()`
`public Nethgui\Log\LogInterface`	# `getLog( )` The log attached to the interface implementor The log attached to the interface implementor Returns `Nethgui\Log\LogInterface` Api Implementation of `Nethgui\Log\LogConsumerInterface::getLog()`
`abstract public Nethgui\Widget\AbstractWidget`	# `insertPlugins( string $name = 'Plugin' )` Insert any (sub)view object found in the view $name collection into the widget. Insert any (sub)view object found in the view $name collection into the widget. Parameters `$name` Optional - Default "Plugin" Returns `Nethgui\Widget\AbstractWidget` the widget itself.
