public class TopicMapping
extends ResourceMapping

A TopicMapping captures configuration information for a pattern-match-based mapping from a proposed NamedTopic name to a topic scheme.

In addition to the mapping between a topic name and a topic scheme, each TopicMapping retains a ParameterResolver (representing user-provided parameters) to be used during the realization of the said topic and scheme. (This allows individual mappings to be parameterized)

Lastly TopicMappings also provide a mechanism to associate specific strongly typed resources with each mapping at runtime. This provides a flexible and dynamic mechanism to associate further configuration information with topics.

Pattern Matching Semantics: The only wildcard permitted for pattern matching with topic names is the "*" and it may only be used at the end of a topic name.

For example, the following topic name patterns are valid: "*" and something-*, but *-something is invalid.

Constructor Details

TopicMapping

public TopicMapping(String sTopicNamePattern,
 String sCachingSchemeName,
 Class<? extends TopicScheme> clsScheme)

Construct a TopicMapping for topics that will use raw types by default.

Parameters:

sTopicNamePattern - the pattern that maps topic names to caching schemes

sCachingSchemeName - the name of the caching scheme to which topics matching this TopicMapping will be associated

Method Details

getConfigElementName

public String getConfigElementName()

Description copied from class: ResourceMapping

Obtain the xml element name of this mapping.

Specified by:

getConfigElementName in class ResourceMapping

Returns:

the xml element name of this mapping

validateScheme

public void validateScheme(Scheme scheme)

Description copied from class: ResourceMapping

Determine whether the specified schem is valid for this mapping type.

Specified by:

validateScheme in class ResourceMapping

Parameters:

scheme - the scheme to validate

getValueClassName

public String getValueClassName()

Obtains the name of the value class for NamedTopics using this TopicMapping.

Returns:

the name of the value class or null if rawtypes are being used

setValueClassName

@Injectable("value-type")
public void setValueClassName(String sElementClassName)

Sets the name of the value class for NamedTopics using this TopicMapping.

Parameters:

sElementClassName - the name of the value class or null if rawtypes are being used

usesRawTypes

public boolean usesRawTypes()

Determines if the TopicMapping is configured to use raw-types (ie: no type checking or constraints)

Returns:

true if using raw types, false otherwise

setSubscriberGroupBuilders

@Injectable("subscriber-groups")
public void setSubscriberGroupBuilders(Collection<SubscriberGroupBuilder> colBuilders)

Set the durable SubscriberGroupBuilders for this TopicMapping.

Parameters:

colBuilders - collection of SubscriberGroupBuilders.

getSubscriberGroupBuilders

public Collection<SubscriberGroupBuilder> getSubscriberGroupBuilders()

Get the durable SubscriberGroupBuilders for this TopicMapping.

Returns:

collection of SubscriberGroupBuilder(s).
