Package com.yahoo.schema

Class MapEvaluationTypeContext

java.lang.Object
com.yahoo.searchlib.rankingexpression.rule.FunctionReferenceContext
com.yahoo.schema.MapEvaluationTypeContext
All Implemented Interfaces:
com.yahoo.tensor.evaluation.TypeContext<com.yahoo.searchlib.rankingexpression.Reference>
public class MapEvaluationTypeContext extends com.yahoo.searchlib.rankingexpression.rule.FunctionReferenceContext implements com.yahoo.tensor.evaluation.TypeContext<com.yahoo.searchlib.rankingexpression.Reference>
A context which only contains type information. This returns empty tensor types (double) for unknown features which are not query, attribute or constant features, as we do not have information about which such features exist (but we know those that exist are doubles). This is not multithread safe.
