Member Function Documentation

__sleep()

TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\ViewHelperNode::__sleep

(

)

Clean up for serializing.

Returns

array

Definition at line 142 of file ViewHelperNode.php.

evaluate()

TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\ViewHelperNode::evaluate

(

\TYPO3\CMS\Fluid\Core\Rendering\RenderingContextInterface

$renderingContext

)

Call the view helper associated with this object.

First, it evaluates the arguments of the view helper.

If the view helper implements , it calls setChildNodes(array childNodes) on the view helper.

Afterwards, checks that the view helper did not leave a variable lying around.

Parameters

\TYPO3\CMS\Fluid\Core\Rendering\RenderingContextInterface

$renderingContext

Returns

object evaluated node after the view helper has been called.

Implements TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\NodeInterface.

getArguments()

TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\ViewHelperNode::getArguments

(

)

INTERNAL - only needed for compiling templates

Returns

array

Definition at line 86 of file ViewHelperNode.php.

getUninitializedViewHelper()

TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\ViewHelperNode::getUninitializedViewHelper

(

)

Returns the attached (but still uninitialized) ViewHelper for this ViewHelperNode. We need this method because sometimes Interceptors need to ask some information from the ViewHelper.

Returns

the attached ViewHelper, if it is initialized

getViewHelperClassName()

TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\ViewHelperNode::getViewHelperClassName

(

)

Get class name of view helper

Returns

string Class Name of associated view helper
