Interface DeferredExecutionSupport

All Known Implementing Classes:

DeferredExecutionSupport.DeferredExecutionSupportImpl, DeferredExecutionSupport.NoOp

public interface DeferredExecutionSupport

The purpose of this class hierarchy is to encapsulate most of the logic for deferring field execution, thus keeping the main execution strategy code clean and focused on the main execution logic.

The DeferredExecutionSupport.NoOp instance should be used when incremental support is not enabled for the current execution. The methods in this class will return empty or no-op results, that should not impact the main execution.

DeferredExecutionSupport.DeferredExecutionSupportImpl is the actual implementation that will be used when incremental support is enabled.
