Method Details

lookupMarshaller

@SafeVarargs
public final <T> BinaryMarshaller<T> lookupMarshaller(Class<T> type,
 Class<? extends Annotation>... annotationTypes)

Looks up BinaryMarshaller for the type and annotationTypes. The method first tries to find a marshaller registered for the type and some annotation from annotationTypes. If no such marshaller exists, it tries to find a marshaller registered just for the type. If there is no such a marshaller it throws the UnsupportedOperationException.

Parameters:

type - the parameter or return type.

annotationTypes - parameter or method annotation types.

Throws:

UnsupportedOperationException - if there is no registered marshaller for the type.

lookupMarshaller

@SafeVarargs
public final <T> BinaryMarshaller<T> lookupMarshaller(TypeLiteral<T> parameterizedType,
 Class<? extends Annotation>... annotationTypes)

Looks up BinaryMarshaller for the parameterizedType and annotationTypes. The method first tries to find a marshaller registered for the parameterizedType and some annotation from annotationTypes. If no such marshaller exists, it tries to find a marshaller registered just for the parameterizedType. If there is no such a marshaller it throws the UnsupportedOperationException.

Parameters:

parameterizedType - the parameter or return type.

annotationTypes - parameter or method annotation types.

Throws:

UnsupportedOperationException - if there is no registered marshaller for the parameterizedType.
