Class AggregationFunctionAdapter
java.lang.Object
nz.org.riskscape.engine.function.agg.AggregationFunctionAdapter
- All Implemented Interfaces:
AutoCloseable,RiskscapeFunction,UntypedFunction,RealizableFunction
public class AggregationFunctionAdapter
extends Object
implements RiskscapeFunction, RealizableFunction
Adapts an AggregationFunction so that it can be called in a standard RealizedExpression.
Supports only single argument functions, but could be extended to support more complex configurations

call
Description copied from interface:UntypedFunctionExecute the function with the given arguments.
- Specified by:
callin interfaceUntypedFunction- Parameters:
args- list of arguments to the function that should conform to the types inArgumentList.getArgumentTypes()
-
getAggregationFunction
- Specified by:
getAggregationFunctionin interfaceRiskscapeFunction- Returns:
- An
AggregationFunctionthat is functionally the same operation as this, but works with aRealizedAggregateExpression, rather than against aRealizedExpressionwith anRSList.

realize
public ResultOrProblems<RiskscapeFunction> realize(RealizationContext context, FunctionCall functionCall, List<Type> argumentTypes) Description copied from interface:RealizableFunctionAttempt to adapt a function call to the given types. This can also be used to do constant optimizations etc or anything else.
- Specified by:
realizein interfaceRealizableFunctionfunctionCall- the part of the abstract syntax tree for the function callargumentTypes- the types of the arguments that have been supplied to the function- Returns:
- the adapted function, or some problems if it couldn't be adapted.
