Expression Builder

The Expression Builder is a convenient fluent interface for building expressions to be used with the Doctrine\Common\Collections\Criteria class:

1$expressionBuilder = Criteria::expr(); $criteria = new Criteria(); $criteria->where($expressionBuilder->eq('name', 'jwage')); $criteria->orWhere($expressionBuilder->eq('name', 'romanb')); $collection->matching($criteria);

The ExpressionBuilder has the following API:

andX

1$expressionBuilder = Criteria::expr(); $expression = $expressionBuilder->andX( $expressionBuilder->eq('foo', 1), $expressionBuilder->eq('bar', 1) ); $collection->matching(new Criteria($expression));

orX

1$expressionBuilder = Criteria::expr(); $expression = $expressionBuilder->orX( $expressionBuilder->eq('foo', 1), $expressionBuilder->eq('bar', 1) ); $collection->matching(new Criteria($expression));
