net.sf.jabb.camel.RegistryUtility

public class RegistryUtility
extends Object

This utility provides convenient methods to work on Camel Registry, however CombinedRegistry is required in most of the cases.
提供方便地对Camel的Registry进行操作的方法，不过大部分的时候只有CombinedRegistry才被支持。

For example, it provides methods to add Codec(s) required by Netty to Registry.
比如说，它提供向Registry中添加Netty所需的Codec的方法。

But you should be aware that it does not ensure multi-threads safe on the manipulation of Registry.
但是注意，它不保证对Registry的操作是多线程安全的。

getCombinedRegistry

public static CombinedRegistry getCombinedRegistry(org.apache.camel.CamelContext camelContext)

Gets CombinedRegistry from CamelContext.
从CamelContext中得到CombinedRegistry类型的Registry。

Parameters:

camelContext - The CamelContext must be based on CombinedRegistry, otherwise ClassCastException will be thrown.
这个context必须是采用CombinedRegistry类型的Registry的，否则会抛出格式转换异常。

Returns:

The Registry that is of CombinedRegistry type.

addEncoder

public static void addEncoder(org.apache.camel.CamelContext context,
                              String name,
                              org.jboss.netty.channel.ChannelDownstreamHandler encoder)

Adds an Netty encoder to Registry.
向Registry中增加一个给Netty用的encoder。

Parameters:

context - The CamelContext must be based on CombinedRegistry, otherwise ClassCastException will be thrown.
这个context必须是采用CombinedRegistry类型的Registry的，否则会抛出格式转换异常。

name - Name of the encoder in Registry.
encoder在Registry中的名字。

encoder - The encoder that will be used by Netty.
将被Netty用到的encoder。

addDecoder

public static void addDecoder(org.apache.camel.CamelContext context,
                              String name,
                              org.jboss.netty.channel.ChannelUpstreamHandler decoder)

Adds an Netty decoder to Registry.
向Registry中增加一个给Netty用的decoder。

Parameters:

context - The CamelContext must be based on CombinedRegistry, otherwise ClassCastException will be thrown.
这个context必须是采用CombinedRegistry类型的Registry的，否则会抛出格式转换异常。

addCodecOnly

protected static void addCodecOnly(CombinedRegistry registry,
                                   String name,
                                   org.jboss.netty.channel.ChannelHandler codec)

Adds codec to Registry only, it will not handle the manipulating of encoders or decoders list in Registry.
仅仅把codec直接加入到Registry中，而不处理加入到Registry里的encoders或decoders列表中。

If a codec with the same name already exists in the Registry, IllegalArgumentException will be thrown.
如果Registry中原先已经有同名的别的codec，则抛出IllegalArgumentException。

Parameters:

registry - The CombinedRegistry that the codec will be added into.
codec将要被加入的CombinedRegistry。
