org.apache.camel.processor.idempotent.jdbc
Class AbstractJdbcMessageIdRepository<T>

java.lang.Object
  org.apache.camel.support.ServiceSupport
      org.apache.camel.processor.idempotent.jdbc.AbstractJdbcMessageIdRepository<T>

All Implemented Interfaces:

org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.IdempotentRepository<T>, org.apache.camel.StatefulService, org.apache.camel.SuspendableService

Direct Known Subclasses:

JdbcMessageIdRepository

@ManagedResource(description="JDBC IdempotentRepository")
public abstract class AbstractJdbcMessageIdRepository<T>
extends org.apache.camel.support.ServiceSupport
implements org.apache.camel.spi.IdempotentRepository<T>

Base class for JDBC-based idempotent repositories that allows the schema to be changed.

Subclasses need only implement theses methods:

• #queryForInt(T key)
• #insert(T key)
• #delete(T key)

These methods should perform the named database operation.
