Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

baseFormat

@Nonnull
public RDFFormat baseFormat()

Return the base format. For example, a ttl file compressed using gzip compression would have ttl as the base format and the compression as FileFormat.Compression.GZIP. Some compressions, notably ZIP, don't have a notion of a base format since they also act as an archive in which case this is meaningless.

Returns:

the base format
