parseURI

public void parseURI(URI uri,
            Map<String,Object> parameters,
            NettyComponent component,

              throws Exception

Throws:

Exception

getCharsetName

public String getCharsetName()

getRequestTimeout

public long getRequestTimeout()

setRequestTimeout

public void setRequestTimeout(long requestTimeout)

Allows to use a timeout for the Netty producer when calling a remote server. By default no timeout is in use. The value is in milli seconds, so eg 30000 is 30 seconds. The requestTimeout is using Netty's ReadTimeoutHandler to trigger the timeout.

public void setSync(boolean sync)

Setting to set endpoint as one-way or request-response

isTextline

public boolean isTextline()

setTextline

public void setTextline(boolean textline)

Only used for TCP. If no codec is specified, you can use this flag to indicate a text line based codec; if not specified or the value is false, then Object Serialization is assumed over TCP.

getDecoderMaxLineLength

public int getDecoderMaxLineLength()

setDecoderMaxLineLength

public void setDecoderMaxLineLength(int decoderMaxLineLength)

The max line length to use for the textline codec.

getDelimiter

public TextLineDelimiter getDelimiter()

setDelimiter

public void setDelimiter(TextLineDelimiter delimiter)

The delimiter to use for the textline codec. Possible values are LINE and NULL.

isAutoAppendDelimiter

public boolean isAutoAppendDelimiter()

setAutoAppendDelimiter

public void setAutoAppendDelimiter(boolean autoAppendDelimiter)

Whether or not to auto append missing end delimiter when sending using the textline codec.

getEncoding

public String getEncoding()

setEncoding

public void setEncoding(String encoding)

The encoding (a charset name) to use for the textline codec. If not provided, Camel will use the JVM default Charset.

getDecoders

public List<io.netty.channel.ChannelHandler> getDecoders()

setDecoders

public void setDecoders(List<io.netty.channel.ChannelHandler> decoders)

A list of decoders to be used. You can use a String which have values separated by comma, and have the values be looked up in the Registry. Just remember to prefix the value with # so Camel knows it should lookup.

getEncoders

public List<io.netty.channel.ChannelHandler> getEncoders()

setEncoders

public void setEncoders(List<io.netty.channel.ChannelHandler> encoders)

A list of encoders to be used. You can use a String which have values separated by comma, and have the values be looked up in the Registry. Just remember to prefix the value with # so Camel knows it should lookup.

getEncoder

public io.netty.channel.ChannelHandler getEncoder()

setEncoder

public void setEncoder(io.netty.channel.ChannelHandler encoder)

A custom ChannelHandler class that can be used to perform special marshalling of outbound payloads.

getDecoder

public io.netty.channel.ChannelHandler getDecoder()

setDecoder

public void setDecoder(io.netty.channel.ChannelHandler decoder)

A custom ChannelHandler class that can be used to perform special marshalling of inbound payloads.

isDisconnect

public boolean isDisconnect()

setDisconnect

public void setDisconnect(boolean disconnect)

Whether or not to disconnect(close) from Netty Channel right after use. Can be used for both consumer and producer.

isLazyChannelCreation

public boolean isLazyChannelCreation()

setLazyChannelCreation

public void setLazyChannelCreation(boolean lazyChannelCreation)

Channels can be lazily created to avoid exceptions, if the remote server is not up and running when the Camel producer is started.

isTransferExchange

public boolean isTransferExchange()

setTransferExchange

public void setTransferExchange(boolean transferExchange)

Only used for TCP. You can transfer the exchange over the wire instead of just the body. The following fields are transferred: In body, Out body, fault body, In headers, Out headers, fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level.

isDisconnectOnNoReply

public boolean isDisconnectOnNoReply()

setDisconnectOnNoReply

public void setDisconnectOnNoReply(boolean disconnectOnNoReply)

If sync is enabled then this option dictates NettyConsumer if it should disconnect where there is no reply to send back.

getNoReplyLogLevel

public org.apache.camel.LoggingLevel getNoReplyLogLevel()

setNoReplyLogLevel

public void setNoReplyLogLevel(org.apache.camel.LoggingLevel noReplyLogLevel)

If sync is enabled this option dictates NettyConsumer which logging level to use when logging a there is no reply to send back.

getServerExceptionCaughtLogLevel

public org.apache.camel.LoggingLevel getServerExceptionCaughtLogLevel()

setServerExceptionCaughtLogLevel

public void setServerExceptionCaughtLogLevel(org.apache.camel.LoggingLevel serverExceptionCaughtLogLevel)

If the server (NettyConsumer) catches an exception then its logged using this logging level.

getServerClosedChannelExceptionCaughtLogLevel

public org.apache.camel.LoggingLevel getServerClosedChannelExceptionCaughtLogLevel()

setServerClosedChannelExceptionCaughtLogLevel

public void setServerClosedChannelExceptionCaughtLogLevel(org.apache.camel.LoggingLevel serverClosedChannelExceptionCaughtLogLevel)

If the server (NettyConsumer) catches an java.nio.channels.ClosedChannelException then its logged using this logging level. This is used to avoid logging the closed channel exceptions, as clients can disconnect abruptly and then cause a flood of closed exceptions in the Netty server.

isAllowDefaultCodec

public boolean isAllowDefaultCodec()

setAllowDefaultCodec

public void setAllowDefaultCodec(boolean allowDefaultCodec)

The netty component installs a default codec if both, encoder/deocder is null and textline is false. Setting allowDefaultCodec to false prevents the netty component from installing a default codec as the first element in the filter chain.

setClientPipelineFactory

@Deprecated
public void setClientPipelineFactory(ClientInitializerFactory clientPipelineFactory)

Deprecated. use #setClientInitializerFactory

getClientPipelineFactory

@Deprecated
public ClientInitializerFactory getClientPipelineFactory()

public void setUsingExecutorService(boolean usingExecutorService)

Whether to use ordered thread pool, to ensure events are processed orderly on the same channel.

getProducerPoolMaxActive

public int getProducerPoolMaxActive()

setProducerPoolMaxActive

public void setProducerPoolMaxActive(int producerPoolMaxActive)

Sets the cap on the number of objects that can be allocated by the pool (checked out to clients, or idle awaiting checkout) at a given time. Use a negative value for no limit.

getProducerPoolMinIdle

public int getProducerPoolMinIdle()

setProducerPoolMinIdle

getProducerPoolMinEvictableIdle

public long getProducerPoolMinEvictableIdle()

setProducerPoolMinEvictableIdle

public void setProducerPoolMinEvictableIdle(long producerPoolMinEvictableIdle)

Sets the minimum amount of time (value in millis) an object may sit idle in the pool before it is eligible for eviction by the idle object evictor.

isProducerPoolEnabled

public boolean isProducerPoolEnabled()

setProducerPoolEnabled

public void setProducerPoolEnabled(boolean producerPoolEnabled)

Whether producer pool is enabled or not. Important: Do not turn this off, as the pooling is needed for handling concurrency and reliable request/reply.

isUdpConnectionlessSending

public boolean isUdpConnectionlessSending()

setUdpConnectionlessSending

public void setUdpConnectionlessSending(boolean udpConnectionlessSending)

This option supports connection less udp sending which is a real fire and forget. A connected udp send receive the PortUnreachableException if no one is listen on the receiving port.

public void setClientMode(boolean clientMode)

If the clientMode is true, netty consumer will connect the address as a TCP client.

isUseByteBuf

public boolean isUseByteBuf()

setUseByteBuf

If the useByteBuf is true, netty producer will turn the message body into ByteBuf before sending it out.

isUdpByteArrayCodec

public boolean isUdpByteArrayCodec()

setUdpByteArrayCodec

public void setUdpByteArrayCodec(boolean udpByteArrayCodec)

For UDP only. If enabled the using byte array codec instead of Java serialization protocol.

isReuseChannel

public boolean isReuseChannel()

setReuseChannel

public void setReuseChannel(boolean reuseChannel)

This option allows producers to reuse the same Netty Channel for the lifecycle of processing the Exchange. This is useable if you need to call a server multiple times in a Camel route and want to use the same network connection. When using this the channel is not returned to the connection pool until the Exchange is done; or disconnected if the disconnect option is set to true.

The reused Channel is stored on the Exchange as an exchange property with the key NettyConstants.NETTY_CHANNEL which allows you to obtain the channel during routing and use it as well.
