Class BaseStateTransferInterceptor

java.lang.Object

org.infinispan.interceptors.BaseAsyncInterceptor

org.infinispan.interceptors.DDAsyncInterceptor

org.infinispan.interceptors.impl.BaseStateTransferInterceptor

All Implemented Interfaces:

Visitor, AsyncInterceptor

Direct Known Subclasses:

StateTransferInterceptor

public abstract class BaseStateTransferInterceptor
extends DDAsyncInterceptor

A base class for a state transfer interceptor. It contains the base code to avoid duplicating in the two current different implementations.

Also, it has some utilities methods with the most common logic.

Since:

9.0
