[TYPO3-mvc] query->matching() constraint replacement.

[Dennis Ahrens]

Hi list,

the method matching() replaces the given constraint - i think it would 
be nice, if an initial constraint will be conjuncted with logicalAnd().

The motivation is the following: It is possible to predefine constraints 
that shall be applied to all queries inside createQuery(). e.g. access 
restriction. Any opinions related to this topic? Any other solutions to 
get a constraint into each query?

Sample implementation:

	/**
	 * The constraint used to limit the result set. Returns $this to allow
	 * for chaining (fluid interface)
	 *
	 * @param Tx_Extbase_Persistence_QOM_ConstraintInterface $constraint
	 * @return Tx_Extbase_Persistence_QueryInterface
	 * @api
	 */
	public function matching($constraint, $replaceConstraint = TRUE) {
		if($this->constraint === NULL) {
				$this->constraint = $constraint;
		} else {
			if ($replaceConstraint === TRUE) {
				$this->constraint = $constraint;
			} else {
				$this->constraint = $this->logicalAnd($this->constraint,$constraint);
			}
		}
		return $this;
	}
