  • Method Details

    • setMissingValue

      public void setMissingValue(com.yahoo.tensor.Tensor value)
      Sets the value to use for lookups to existing values which are not set in this context. The default value that will be returned is NaN

    • put

      public void put(String name, com.yahoo.searchlib.rankingexpression.evaluation.Value value)
      Puts a value by name. The value will be frozen if it isn't already.
      Overrides:
      put in class com.yahoo.searchlib.rankingexpression.evaluation.Context
      Throws:
      IllegalArgumentException - if the name is not present in the ranking expression this was created with, and ignoredUnknownValues is false

    • put

      public final void put(int index, double value)
      Same as put(index,DoubleValue.frozen(value))

    • put

      public void put(int index, com.yahoo.searchlib.rankingexpression.evaluation.Value value)
      Puts a value by index. The value will be frozen if it isn't already.
