/**
|
|
* Validates values against constraints defined in {@link MetadataInterface}
|
|
* instances.
|
|
*
|
|
* This interface is an implementation of the Visitor design pattern. A value
|
|
* is validated by first passing it to the {@link validate} method. That method
|
|
* will determine the matching {@link MetadataInterface} for validating the
|
|
* value. It then calls the {@link MetadataInterface::accept} method of that
|
|
* metadata. <tt>accept()</tt> does two things:
|
|
*
|
|
* <ol>
|
|
* <li>It calls {@link visit} to validate the value against the constraints of
|
|
* the metadata.</li>
|
|
* <li>It calls <tt>accept()</tt> on all nested metadata instances with the
|
|
* corresponding values extracted from the current value. For example, if the
|
|
* current metadata represents a class and the current value is an object of
|
|
* that class, the metadata contains nested instances for each property of that
|
|
* class. It forwards the call to these nested metadata with the values of the
|
|
* corresponding properties in the original object.</li>
|
|
* </ol>
