Class StatementHolder

java.lang.Object

org.vibur.dbcp.stcache.StatementHolder

public class StatementHolder
extends Object

A thin wrapper around the raw JDBC Statement object which allows us to augment it with useful "state" information. The instances of this class are used as a cached value (in a ConcurrentMap cache implementation) for the invocations of Connection.prepareStatement and Connection.prepareCall methods, and their "state" is describing whether the Statement object is currently AVAILABLE, IN_USE, or EVICTED.
