Method Details

apply

Object apply(List<Object> arguments)

Apply the arguments to produce the result.

The result does not need to match the JavaFunction returnType exactly as it will be coerced by JavaFunction.call(java.util.List) before being returned.

Specified by:

apply in interface Function<List<Object>,Object>

Parameters:

arguments - the arguments as passed to JavaFunction.call(java.util.List)

Returns:

the result of processing the arguments

validate

default List<Problem> validate()

getArguments

default ArgumentList getArguments()

Called by JavaFunction.getArguments() to allow the delegate the option to provide an ArgumentList which enables keyword arguments to be used when the function is called.

If Delegates do not wish to provide the argument list the default implementation should not be overridden.
