public interface Decision<T,U>
extends Rule<T>

Method Summary

Modifier and Type	Method and Description
U	getResult() The getResult() method returns the stored result from the Decision The value may be null.
void	setResult(Result<U> result) The setResult() method initializes the stored result; useful for aggregation/chaining of a result.
Decision<T,U>	then(java.util.function.BiFunction<FactMap<T>,Result<U>,RuleState> action) The then method specifies the action taken if when() evaluates to true.

Method Detail

then

Decision<T,U> then(java.util.function.BiFunction<FactMap<T>,Result<U>,RuleState> action)

The then method specifies the action taken if when() evaluates to true. The execution of this 'then' takes precedence over then(Function) if both exist.

Parameters:

action - the action to be performed

Returns:

the current Rule object

getResult

U getResult()

The getResult() method returns the stored result from the Decision The value may be null.

Returns:

the result object

setResult

void setResult(Result<U> result)
