Method Detail

getExtractorType

Class<T> getExtractorType()

Returns the extractor type.

Returns:

the not null extractor class.

createExtractor

T createExtractor()

Creates an extractor instance.

Returns:

an instance of the extractor associated to this factory.

getSupportedMIMETypes

Collection<MIMEType> getSupportedMIMETypes()

Supports wildcards, e.g. "*/*" for blind extractors that merely call a web service.

getExampleInput

String getExampleInput()

An example input file for the extractor, to be used in auto-generated documentation. For the Extractor.BlindExtractor, this is an arbitrary URI. For extractors that require content, it is the name of a file, relative to the factory's class file's location, it will be opened using factory.getClass().getResourceAsStream(filename). The example should be a short file that produces characteristic output if sent through the extractor. The file will be read as UTF-8, so it should either use that encoding or avoid characters outside of the US-ASCII range.
