Method Details

initBundles

public static void initBundles(ConfigurationContext context)

Process initialization for initially registered and all transitive bundles.

• Executing initial bundles initialization (registered in GuiceBundle and by bundle lookup)
• During execution bundles may register other bundles (through GuiceyBootstrap)
• Execute registered bundles and repeat from previous step until no new bundles registered

Bundles duplicates are checked by type: only one bundle instance may be registered.

Parameters:

context - configuration context

initBundles

public static void initBundles(ConfigurationContext context,
 GuiceyBootstrap bootstrap,
 List<Class<? extends GuiceyBundle>> path,
 List<GuiceyBundle> initOrder,
 List<GuiceyBundle> bundles)

Point of root (registered in guice bundle) bundles installation. Also, called in guicey bootstrap for transitive bundles installation (immediate initialization).

Parameters:

context - configuration context

bootstrap - guicey bootstrap object

path - transitive bundles installation path

initOrder - bundles initialization order (appendable)

bundles - bundles to install

runBundles

public static void runBundles(ConfigurationContext context)
                       throws Exception

Run all enabled bundles (and delayed configurations).

Parameters:

context - bundles context

Throws:

Exception - if something goes wrong

removeDuplicates

public static <T> List<T> removeDuplicates(List<T> list)

Remove duplicates in list by rule: only one instance of type must be present in list.

Type Parameters:

T - required bundle type

Parameters:

list - bundles list

Returns:

list cleared from duplicates

removeTypes

public static <T> List<T> removeTypes(List<T> list,
 List<Class<? extends T>> filter)

Filter list from objects of type present in filter list.

Type Parameters:

T - required type

Parameters:

list - list to filter

filter - types to filter

Returns:

filtered list

findBundles

public static <T> List<T> findBundles(io.dropwizard.core.setup.Bootstrap bootstrap,
 Class<T> type)

Type Parameters:

T - required bundle type

Parameters:

bootstrap - dropwizard bootstrap instance

type - required bundle type (or marker interface)

Returns:

list of bundles of specified type
