Examples of ScalarFunction

com.facebook.presto.operator.scalar.ScalarFunction
com.google.visualization.datasource.query.scalarfunction.ScalarFunction
A scalar function. A scalar function can have any arity, including 0, and can also have dynamic arity. It must always produce a single value. The return type of such a function may depend on the number and types of its arguments but never on their values. An instance of a class that implements this interface can be used within a ScalarFunctionColumn. @author Liron L.
org.jboss.dashboard.function.ScalarFunction
Interface used to get the scalar value of a given collection.
Scalar functions are used in BAM to calculate the scalar values of the intervals belonging to a given data set domain property. @see org.jboss.dashboard.domain.Domain @see org.jboss.dashboard.domain.Interval
