java.lang.Objectorg.jboss.netty.bootstrap.Bootstrap
public class Bootstrap
A helper class which initializes a Channel
. This class provides
the common data structure for its subclasses which actually initialize
Channel
s and their child Channel
s using the common data
structure. Please refer to ClientBootstrap
, ServerBootstrap
,
and ConnectionlessBootstrap
for client side, server-side, and
connectionless (e.g. UDP) channel initialization respectively.
Constructor Summary | |
---|---|
protected |
Bootstrap()
Creates a new instance with no ChannelFactory set. |
protected |
Bootstrap(ChannelFactory channelFactory)
Creates a new instance with the specified initial ChannelFactory . |
Method Summary | |
---|---|
ChannelFactory |
getFactory()
Returns the ChannelFactory that will be used to perform an
I/O operation. |
Object |
getOption(String key)
Returns the value of the option with the specified key. |
Map<String,Object> |
getOptions()
Returns the options which configures a new Channel and its
child Channel s. |
ChannelPipeline |
getPipeline()
Returns the default ChannelPipeline which is cloned when a new
Channel is created. |
Map<String,ChannelHandler> |
getPipelineAsMap()
Dependency injection friendly convenience method for getPipeline() which returns the default pipeline of this
bootstrap as an ordered map. |
ChannelPipelineFactory |
getPipelineFactory()
Returns the ChannelPipelineFactory which creates a new
ChannelPipeline for each new Channel . |
void |
releaseExternalResources()
Releases the external resources that this object depends on. |
void |
setFactory(ChannelFactory factory)
Sets the ChannelFactory that will be used to perform an I/O
operation. |
void |
setOption(String key,
Object value)
Sets an option with the specified key and value. |
void |
setOptions(Map<String,Object> options)
Sets the options which configures a new Channel and its child
Channel s. |
void |
setPipeline(ChannelPipeline pipeline)
Sets the default ChannelPipeline which is cloned when a new
Channel is created. |
void |
setPipelineAsMap(Map<String,ChannelHandler> pipelineMap)
Dependency injection friendly convenience method for setPipeline(ChannelPipeline) which sets the default pipeline of
this bootstrap from an ordered map. |
void |
setPipelineFactory(ChannelPipelineFactory pipelineFactory)
Sets the ChannelPipelineFactory which creates a new
ChannelPipeline for each new Channel . |

public ChannelFactory getFactory()
ChannelFactory
that will be used to perform an
I/O operation.
IllegalStateException
- if the factory is not set for this bootstrap yet.
The factory can be set in the constructor or
setFactory(ChannelFactory)
.public void setFactory(ChannelFactory factory)
ChannelFactory
that will be used to perform an I/O
operation. This method can be called only once and can't be called at
all if the factory was specified in the constructor.
IllegalStateException
- if the factory is already setpublic ChannelPipeline getPipeline()
ChannelPipeline
which is cloned when a new
Channel
is created. Bootstrap
creates a new pipeline
which has the same entries with the returned pipeline for a new
Channel
.
Please note that this method is a convenience method that works only
when 1) you create only one channel from this bootstrap (e.g.
one-time client-side or connectionless channel) or 2) all handlers
in the pipeline is stateless. You have to use
setPipelineFactory(ChannelPipelineFactory)
if 1) your
pipeline contains a stateful ChannelHandler
and 2) one or
more channels are going to be created by this bootstrap (e.g. server-side
channels).
ChannelPipeline
IllegalStateException
- if setPipelineFactory(ChannelPipelineFactory)
was
called by a user last time.public void setPipeline(ChannelPipeline pipeline)
ChannelPipeline
which is cloned when a new
Channel
is created. Bootstrap
creates a new pipeline
which has the same entries with the specified pipeline for a new channel.
Calling this method also sets the pipelineFactory
property to an
internal ChannelPipelineFactory
implementation which returns
a shallow copy of the specified pipeline.
Please note that this method is a convenience method that works only
when 1) you create only one channel from this bootstrap (e.g.
one-time client-side or connectionless channel) or 2) all handlers
in the pipeline is stateless. You have to use
setPipelineFactory(ChannelPipelineFactory)
if 1) your
pipeline contains a stateful ChannelHandler
and 2) one or
more channels are going to be created by this bootstrap (e.g. server-side
channels).
public Map<String,ChannelHandler> getPipelineAsMap()
getPipeline()
which returns the default pipeline of this
bootstrap as an ordered map.
Please note that this method is a convenience method that works only
when 1) you create only one channel from this bootstrap (e.g.
one-time client-side or connectionless channel) or 2) all handlers
in the pipeline is stateless. You have to use
setPipelineFactory(ChannelPipelineFactory)
if 1) your
pipeline contains a stateful ChannelHandler
and 2) one or
more channels are going to be created by this bootstrap (e.g. server-side
channels).
IllegalStateException
- if setPipelineFactory(ChannelPipelineFactory)
was
called by a user last time.public void setPipelineAsMap(Map<String,ChannelHandler> pipelineMap)
setPipeline(ChannelPipeline)
which sets the default pipeline of
this bootstrap from an ordered map.
Please note that this method is a convenience method that works only
