Methods in eu.fbk.rdfpro that return Transformer

Modifier and Type	Method and Description
static Transformer	Transformer.filter(Predicate<? super org.openrdf.model.Statement> predicate) Returns a Transformer that emits only statements matching the supplied Predicate.
static Transformer	Transformer.filter(String components, Predicate<? super org.openrdf.model.Value> predicate) Returns a Transformer that emits only statements whose selected component matches the specified Predicate.
static Transformer	Transformer.map(Function<? super org.openrdf.model.Statement,? extends org.openrdf.model.Statement> function) Returns a Transformer that applies the supplied function to each input statement, emitting its output if not null.
static Transformer	Transformer.map(String components, Function<? super org.openrdf.model.Value,? extends org.openrdf.model.Value> function) Returns a Transformer that replaces selected components of the input statement using the supplied function.
