The method validate uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them.

            $errors = $this->validator->validate($entity);

            if (0 < count($errors)) {
                throw new Validation\ValidationException($errors);

ElseExpression

Since: 1.4.0

An if expression with an else branch is basically not necessary. You can rewrite the conditions in a way that the else clause is not necessary and the code becomes simpler to read. To achieve this, use early return statements, though you may need to split the code it several smaller methods. For very simple assignments you could also use the ternary operations.

Example

class Foo
{
    public function bar($flag)
    {
        if ($flag) {
            // one branch
        } else {
            // another branch
        }
    }
}
