Interface FileExtractorFactory

All Known Implementing Classes:

MP3FileExtractorFactory

public interface FileExtractorFactory

A FileExtractorFactory create instances of a specific FileExtractor implementation. As such, it embodies knowledge about whether a singleton or unique instances are best returned and for which MIME types the FileExtractors can be used.

FileExtractorFactories should be very light-weight to create. This allows them to be used for service registration in service-oriented architectures.
