Returns:

the type that this function should return

getArgumentTypes

public List<Type> getArgumentTypes()

Specified by:

Parameters:

args - list of arguments to the function that should conform to the types in ArgumentList.getArgumentTypes()

getArguments

public ArgumentList getArguments()

getArguments in interface RiskscapeFunction

getOverloaded

public Optional<OverloadedFunction> getOverloaded()

Specified by:

getOverloaded in interface RiskscapeFunction

Returns:

an OverloadedFunction that offers alternative input types for use within an expression, or empty if this function does not support overloading

getRealizable

public Optional<RealizableFunction> getRealizable()

Specified by:

getRealizable in interface RiskscapeFunction

Returns:

a RealizableFunction that can realize this RiskscapeFunction against a type, or empty if this function does not support realization.

getAggregationFunction

public Optional<AggregationFunction> getAggregationFunction()

Specified by:

getAggregationFunction in interface RiskscapeFunction

Returns:

An AggregationFunction that is functionally the same operation as this, but works with a RealizedAggregateExpression, rather than against a RealizedExpression with an RSList.

getWrappedFunction

public RiskscapeFunction getWrappedFunction()
