Class	Description
ScalarValuedFunction	The description of a function taking record data and producing a scalar result.

Classes in com.pervasive.datarush.functions used by com.pervasive.datarush.annotations
Class	Description
ArgumentConverter	An ArgumentConverter is used by the `DefaultFunctionInvoker` to convert ScalarValuedFunction arguments to the correct type.
FunctionInvoker	A FunctionInvoker is used by the FunctionRegistry to invoke a function method and by the AggregationInvoker to invoke an aggregation method. The implementing class essentially translates an array of ScalarValuedFunction arguments into the proper format for a given function method. A function method can specify its invoker using the Invoker annotation.

DateTime.Granularity	The desired granularity of the output.
EvaluationContext	An object describing the context in which a subexpression of a larger expression is being evaluated.
EvaluatorFactory	A factory used to construct evaluators for `ScalarValuedFunction`s.
FunctionContext	Information about the context in which a function is evaluated.
FunctionDescription	A description of a function, including its name, description, and argument names.
FunctionEvaluator	An executor of a function.
FunctionInvoker	A FunctionInvoker is used by the FunctionRegistry to invoke a function method and by the AggregationInvoker to invoke an aggregation method.

A function method can specify its invoker using the Invoker annotation.
FunctionProvider	A provider of registered classes for the `FunctionRegistry`.
FunctionRegistry	Stores a list of functions registered by the FunctionTypeResoultionProvider, and provides a method for calling those functions.
FunctionTyper	Determines the upper bound and result type of a `ScalarValuedFunction`.
MappedEvaluatorFactory	A base class for factories which choose an evaluator based on a token type.
