Generate entity classes and method stubs from your mapping information.

If you use the <comment>--update-entities</comment> or <comment>--regenerate-entities</comment> flags your exisiting

code gets overwritten. The EntityGenerator will only append new code to your

file and will not delete the old code. However this approach may still be prone

to error and we suggest you use code repositories such as GIT or SVN to make

backups of your code.

It makes sense to generate the entity code if you are using entities as Data

Access Objects only and dont put much additional logic on them. If you are

however putting much more logic on the entities you should refrain from using

the entity-generator and code your entities manually.

<error>Important:</error> Even if you specified Inheritance options in your

XML or YAML Mapping files the generator cannot generate the base and

child classes for you correctly, because it doesn't know which

class is supposed to extend which. You have to adjust the entity

code manually for inheritance to work!
