Class DynamicRouterDefinition<Type extends ProcessorDefinition<Type>>

    • Method Detail

      • getLabel

        public String getLabel()
        Description copied from class: ProcessorDefinition
        Returns a label to describe this node such as the expression if some kind of expression node
        Specified by:
        getLabel in interface org.apache.camel.NamedNode
        Overrides:
        getLabel in class ExpressionNode
      • setExpression

        public void setExpression​(ExpressionDefinition expression)
        Expression to call that returns the endpoint(s) to route to in the dynamic routing.

        Important: The expression will be called in a while loop fashion, until the expression returns null which means the dynamic router is finished.

        Overrides:
        setExpression in class ExpressionNode
      • cacheSize

        public DynamicRouterDefinition<TypecacheSize​(int cacheSize)
        Sets the maximum size used by the ProducerCache which is used to cache and reuse producers when using this dynamic router, when uris are reused. Beware that when using dynamic endpoints then it affects how well the cache can be utilized. If each dynamic endpoint is unique then its best to turn of caching by setting this to -1, which allows Camel to not cache both the producers and endpoints; they are regarded as prototype scoped and will be stopped and discarded after use. This reduces memory usage as otherwise producers/endpoints are stored in memory in the caches. However if there are a high degree of dynamic endpoints that have been used before, then it can benefit to use the cache to reuse both producers and endpoints and therefore the cache size can be set accordingly or rely on the default size (1000). If there is a mix of unique and used before dynamic endpoints, then setting a reasonable cache size can help reduce memory usage to avoid storing too many non frequent used producers.
        Parameters:
        cacheSize - the cache size, use 0 for default cache size, or -1 to turn cache off.
        Returns:
        the builder
