Method Detail

getDataAsInputStream

protected InputStream getDataAsInputStream()

Description copied from class: AbstractNIFDataset

This method returns an opened InputStream from which the NIF data will be read. If an error occurs while opening the stream, null should be returned. Note that for closing the stream AbstractNIFDataset.closeInputStream(InputStream) is called. If there are other resources related to this stream that have to be closed, this method can be overwritten to free these resources, too.

Specified by:

getDataAsInputStream in class AbstractNIFDataset

Returns:

an opened InputStream or null if an error occurred.

getDataLanguage

protected org.apache.jena.riot.Lang getDataLanguage()

Description copied from class: AbstractNIFDataset

This method returns the language of the NIF data, e.g., Lang.TURTLE.

Specified by:

getDataLanguage in class AbstractNIFDataset

Returns:

the language of the NIF data

fileExtToLang

protected static org.apache.jena.riot.Lang fileExtToLang(String filePath)
