Class CmdInfoFlyweightFactory

java.lang.Object

com.iohao.net.framework.core.CmdInfoFlyweightFactory

public final class CmdInfoFlyweightFactory
extends Object

Factory that produces cached CmdInfo instances using the flyweight pattern.

The underlying caching strategy is selected at class-load time based on CmdInfoFlyweightStrategy configured in CoreGlobalConfig.setting. When the command space exceeds 128 in either dimension the factory automatically falls back to a Map-based implementation.
