Examples of org.openrdf.query.resultio.BooleanQueryResultFormat

org.openrdf.query.resultio.BooleanQueryResultFormat
Represents the concept of a boolean query result serialization format. Boolean query result formats are identified by a {@link #getName() name} andcan have one or more associated MIME types, zero or more associated file extensions and can specify a (default) character encoding. @author Arjohn Kampman
