getArrayInputs
public Set<Expr> getArrayInputs(List<Expr> args)
Description copied from interface:Function
Given a list of arguments to thisFunction
, get the set of arguments that must evaluate to an array value- Specified by:
getArrayInputs
in interfaceFunction
- Overrides:
getArrayInputs
in classFunction.ArraysFunction
-
hasArrayOutput
public boolean hasArrayOutput()
Description copied from interface:Function
Returns true if function produces an array. AllFunction
implementations are expected to exclusively produce either scalar or array values.
-
getOutputType
@Nullable public ExpressionType getOutputType(Expr.InputBindingInspector inspector, List<Expr> args)
Description copied from interface:Function
Compute the output type of this function for a given set of argument expression inputs.
