Parameters:

extension - the file extension for which a loader should be found.

Returns:

a RoutesBuilderLoader

Throws:

IllegalArgumentException - if no RoutesBuilderLoader can be found for the given file extension

Exception

loadRoutes

default void loadRoutes(Collection<Resource> resources)
                 throws Exception

Loads RoutesBuilder from the give list of Resource into the current CamelContext.

Parameters:

resources - the resources to be loaded.

Throws:

Exception

loadRoutes

default void loadRoutes(Resource... resources)
                 throws Exception

Loads RoutesBuilder from the give list of Resource into the current CamelContext.

Parameters:

resources - the resources to be loaded.

Throws:

Exception

updateRoutes

default Set<String> updateRoutes(Resource... resources)
                          throws Exception

Loads or updates existing RoutesBuilder from the give list of Resource into the current CamelContext. If a route is loaded with a route id for an existing route, then the existing route is stopped and remove, so it can be updated.

Parameters:

resources - the resources to be loaded or updated.

Returns:

route ids for the routes that was loaded or updated.

Throws:

Exception

updateRoutes

Set<String> updateRoutes(Collection<Resource> resources)
                  throws Exception

Loads or updates existing RoutesBuilder from the give list of Resource into the current CamelContext. If a route is loaded with a route id for an existing route, then the existing route is stopped and remove, so it can be updated.

Parameters:

resources - the resources to be loaded or updated.

Returns:

route ids for the routes that was loaded or updated.

Throws:

Exception

findRoutesBuilders

default Collection<RoutesBuilder> findRoutesBuilders(Resource... resources)
                                              throws Exception

Find RoutesBuilder from the give list of Resource.

Parameters:

resources - the resource to be loaded.

Returns:

a collection of RoutesBuilder

Throws:

Exception

findRoutesBuilders

Collection<RoutesBuilder> findRoutesBuilders(Collection<Resource> resources)
                                      throws Exception

Find RoutesBuilder from the give list of Resource.

Parameters:

resources - the resource to be loaded.

Returns:

a collection RoutesBuilder

Throws:

Exception

findRoutesBuilders

Collection<RoutesBuilder> findRoutesBuilders(Collection<Resource> resources,
 boolean optional)
                                      throws Exception

Find RoutesBuilder from the give list of Resource.

Parameters:

resources - the resource to be loaded.

optional - whether parsing the resource is optional, such as there is no supported parser for the given resource extension

Returns:

a collection RoutesBuilder

Throws:

Exception

preParseRoute

default void preParseRoute(Resource resource,
 boolean optional)
                    throws Exception

optional - whether parsing the resource is optional, such as there is no supported parser for the given resource extension

Throws:
