Expressions =========== The ``Doctrine\Common\Collections\Expr\Comparison`` class can be used to create expressions to be used with the ``Doctrine\Common\Collections\Criteria`` class. It has the following operator constants: - ``Comparison::EQ`` - ``Comparison::NEQ`` - ``Comparison::LT`` - ``Comparison::LTE`` - ``Comparison::GT`` - ``Comparison::GTE`` - ``Comparison::IS`` - ``Comparison::IN`` - ``Comparison::NIN`` - ``Comparison::CONTAINS`` - ``Comparison::MEMBER_OF`` - ``Comparison::STARTS_WITH`` - ``Comparison::ENDS_WITH`` The ``Doctrine\Common\Collections\Criteria`` class has the following API to be used with expressions: where ----- Sets the where expression to evaluate when this Criteria is searched for. .. code-block:: php $expr = new Comparison('key', Comparison::EQ, 'value'); $criteria->where($expr); andWhere -------- Appends the where expression to evaluate when this Criteria is searched for using an AND with previous expression. .. code-block:: php $expr = new Comparison('key', Comparison::EQ, 'value'); $criteria->andWhere($expr); orWhere ------- Appends the where expression to evaluate when this Criteria is searched for using an OR with previous expression. .. code-block:: php $expr1 = new Comparison('key', Comparison::EQ, 'value1'); $expr2 = new Comparison('key', Comparison::EQ, 'value2'); $criteria->where($expr1); $criteria->orWhere($expr2); orderBy ------- Sets the ordering of the result of this Criteria. .. code-block:: php $criteria->orderBy(['name' => Criteria::ASC]); setFirstResult -------------- Set the number of first result that this Criteria should return. .. code-block:: php $criteria->setFirstResult(0); getFirstResult -------------- Gets the current first result option of this Criteria. .. code-block:: php $criteria->setFirstResult(10); echo $criteria->getFirstResult(); // 10 setMaxResults ------------- Sets the max results that this Criteria should return. .. code-block:: php $criteria->setMaxResults(20); getMaxResults ------------- Gets the current max results option of this Criteria. .. code-block:: php $criteria->setMaxResults(20); echo $criteria->getMaxResults(); // 20
