Interface MimeTypeRegistryProvider

All Known Implementing Classes:
MimeTypeRegistryProviderImpl
public interface MimeTypeRegistryProvider
This interface defines a factory for MimeTypeRegistry. An implementation of this interface should provide instances of the MimeTypeRegistry based on the way how to access the storage for MimeTypeEntries.

Jakarta Activation uses Service Provider Interface and ServiceLoader to obtain an instance of the implementation of the MimeTypeRegistryProvider.
