What are the annotations for the doctrine orm?


Asked by Reina Khan on Dec 02, 2021 FAQ



Doctrine ORM docblock annotations support namespaces and nested annotations among other things. The Doctrine ORM ORM defines its own set of docblock annotations for supplying object-relational mapping metadata.
Next,
Annotations in Doctrine are used for the ORM configuration to build the class mapping, but it can be used in other projects for other purposes too. You can install the Annotation component with composer: An annotation class is a representation of the later used annotation configuration in classes.
Consequently, Doctrine Annotations allows to implement custom annotation functionality for PHP classes. Annotations aren't implemented in PHP itself which is why this component offers a way to use the PHP doc-blocks as a place for the well known annotation syntax using the @ char.
In this manner,
If this is larger than 1 (one) Doctrine can generate identifier values for the allocationSizes amount of entities. In the above example with allocationSize=100 Doctrine ORM would only need to access the sequence once to generate the identifiers for 100 new entities.
Moreover,
For annotation autoloading you have to configure the Doctrine\Common\Annotations\AnnotationRegistry. There are three different mechanisms to configure annotation autoloading: Calling AnnotationRegistry#registerFile ($file) to register a file that contains one or more annotation classes.
