Interface PayloadReducer

All Superinterfaces:
BiFunction<Map<String,@Nullable Object>,Map<String,@Nullable Object>,Map<String,@Nullable Object>>
All Known Implementing Classes:
CombineGlobalAndLocalPayloadReducer, GlobalOnlyPayloadReducer, LocalOnlyPayloadReducer
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface PayloadReducer extends BiFunction<Map<String,@Nullable Object>,Map<String,@Nullable Object>,Map<String,@Nullable Object>>
Payload reducer to combine two payloads into one. In general, there is a global payload (part of the state of the workflow instance) and a local payload (part of the step execution). On the step invocation, the global and local form the invocation parameters. After the step execution, the local result and global payload form the resulting workflow instance payload.
