# Class EvictionConfig

java.lang.Object
org.apache.tomcat.dbcp.pool2.impl.EvictionConfig

public class EvictionConfig extends Object
This class is used by pool implementations to pass configuration information to `EvictionPolicy` instances. The `EvictionPolicy` may also have its own specific configuration attributes.

This class is immutable and thread-safe.

Since:
  2.0
