Detailed Description

A node which is used inside boolean arguments

Definition at line 17 of file BooleanNode.php.

Constructor & Destructor Documentation

__construct ( \TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\AbstractNode $syntaxTreeNode )

Constructor. Parses the syntax tree node and fills $this->leftSide, $this->rightSide, $this->comparator and $this->syntaxTreeNode.

Parameters

\TYPO3\CMS\Fluid\Core\Parser\SyntaxTree\AbstractNode $syntaxTreeNode

Exceptions

\TYPO3\CMS\Fluid\Core\Parser\Exception

Definition at line 98 of file BooleanNode.php.

References AbstractNode\$childNodes, BooleanNode\$syntaxTreeNode, elseif, and BooleanNode\getComparatorFromString().

Member Function Documentation

static convertToBoolean ( $value )

static

Convert argument strings to their equivalents. Needed to handle strings with a boolean meaning.

Must be public and static as it is used from inside cached templates.

Parameters

mixed $value Value to be converted to boolean

Returns: bool

Definition at line 326 of file BooleanNode.php.

evaluate ( \TYPO3\CMS\Fluid\Core\Rendering\RenderingContextInterface $renderingContext )

Parameters

\TYPO3\CMS\Fluid\Core\Rendering\RenderingContextInterface $renderingContext

Returns: bool the boolean value

Implements NodeInterface.

Definition at line 195 of file BooleanNode.php.

static evaluateComparator	(	$comparator,
		$evaluatedLeftSide,
		$evaluatedRightSide
	)

static

Do the actual comparison. Compares $leftSide and $rightSide with $comparator and emits a boolean value.

Some special rules apply:

The == and != operators are comparing the Object Identity using === and !==, when one of the two operands are objects.
For arithmetic comparisons (%, >, >=, <, <=), some special rules apply:
- arrays are only comparable with arrays, else the comparison yields FALSE
- objects are only comparable with objects, else the comparison yields FALSE
- the comparison is FALSE when two types are not comparable according to the table "Comparison with various types" on http://php.net/manual/en/language.operators.comparison.php

This function must be static public, as it is also directly called from cached templates.

Parameters

string	$comparator
mixed	$evaluatedLeftSide
mixed	$evaluatedRightSide

Returns: bool TRUE if comparison of left and right side using the comparator emit TRUE, false otherwise

Exceptions

\TYPO3\CMS\Fluid\Core\Parser\Exception

Definition at line 225 of file BooleanNode.php.

References BooleanNode\$comparator.

getComparator ( )

Returns: string

Definition at line 159 of file BooleanNode.php.

References BooleanNode\$comparator.

getComparatorFromString ( $string )

protected

Determine if there is a comparator inside $string, and if yes, returns it.

Parameters

string $string string to check for a comparator inside

Returns: string The comparator or NULL if none found.

static isComparable	(	$evaluatedLeftSide,
		$evaluatedRightSide
	)

staticprotected

Checks whether two operands are comparable (based on their types). This implements the "Comparison with various types" table from http://php.net/manual/en/language.operators.comparison.php, only leaving out "array" with "anything" and "object" with anything; as we specify that arrays and objects are incomparable with anything else than their type.

Parameters

mixed	$evaluatedLeftSide
mixed	$evaluatedRightSide

Returns: bool TRUE if the operands can be compared using arithmetic operators, FALSE otherwise.
