Modifier and Type	Method and Description
protected java.util.Collection<MessageChannel>	determineTargetChannels(Message<?> message) Subclasses must implement this method to return a Collection of zero or more MessageChannels to which the given Message should be routed.
protected abstract java.util.List<java.lang.Object>	getChannelKeys(Message<?> message) Subclasses must implement this method to return the channel keys.
protected java.util.Map<java.lang.String,java.lang.String>	getChannelMappings() Returns an unmodifiable version of the channel mappings.
void	onInit() Subclasses may implement this for initialization logic.
void	removeChannelMapping(java.lang.String key) Remove a channel mapping for the given key if present.
void	setChannelMapping(java.lang.String key, java.lang.String channelName) Add a channel mapping from the provided key to channel name.
void	setChannelMappings(java.util.Map<java.lang.String,java.lang.String> channelMappings) Provide mappings from channel keys to channel names.
void	setChannelResolver(ChannelResolver channelResolver) Specify the ChannelResolver strategy to use.
void	setPrefix(java.lang.String prefix) Specify a prefix to be added to each channel name prior to resolution.
void	setResolutionRequired(boolean resolutionRequired) Specify whether this router should ignore any failure to resolve a channel name to an actual MessageChannel instance when delegating to the ChannelResolver strategy.
void	setSuffix(java.lang.String suffix) Specify a suffix to be added to each channel name prior to resolution.

Method Detail

setChannelMappings

public void setChannelMappings(java.util.Map<java.lang.String,java.lang.String> channelMappings)

Provide mappings from channel keys to channel names. Channel names will be resolved by the ChannelResolver.

setChannelResolver

public void setChannelResolver(ChannelResolver channelResolver)

Specify the ChannelResolver strategy to use. The default is a BeanFactoryChannelResolver. This is considered an infrastructural configuration option and as of 2.1 has been deprecated as a configuration-driven attribute.

setPrefix

public void setPrefix(java.lang.String prefix)

Specify a prefix to be added to each channel name prior to resolution.

setSuffix

public void setSuffix(java.lang.String suffix)

Specify a suffix to be added to each channel name prior to resolution.

setResolutionRequired

public void setResolutionRequired(boolean resolutionRequired)

Specify whether this router should ignore any failure to resolve a channel name to an actual MessageChannel instance when delegating to the ChannelResolver strategy.

getChannelMappings

protected java.util.Map<java.lang.String,java.lang.String> getChannelMappings()

Returns an unmodifiable version of the channel mappings. This is intended for use by subclasses only.

setChannelMapping

@ManagedOperation
public void setChannelMapping(java.lang.String key,
                                      java.lang.String channelName)

Add a channel mapping from the provided key to channel name.

Specified by:

setChannelMapping in interface MappingMessageRouterManagement

removeChannelMapping

@ManagedOperation
public void removeChannelMapping(java.lang.String key)

Remove a channel mapping for the given key if present.

Specified by:

removeChannelMapping in interface MappingMessageRouterManagement

onInit

public void onInit()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class IntegrationObjectSupport

getChannelKeys

protected abstract java.util.List<java.lang.Object> getChannelKeys(Message<?> message)

Subclasses must implement this method to return the channel keys. A "key" might be present in this router's "channelMappings", or it could be the channel's name or even the Message Channel instance itself.

determineTargetChannels

protected java.util.Collection<MessageChannel> determineTargetChannels(Message<?> message)

Description copied from class: AbstractMessageRouter

Subclasses must implement this method to return a Collection of zero or more MessageChannels to which the given Message should be routed.

Specified by:

determineTargetChannels in class AbstractMessageRouter
