Method Detail

add

public void add(String id,
                T object,
                String... constraints)

Description copied from interface: OrderedConfiguration

Adds an ordered object to a service's contribution. Each object has an id (which must be unique). Optionally, pre-requisites (a list of ids that must precede this object) and post-requisites (ids that must follow) can be provided.

If no constraints are supplied, then an implicit constraint is supplied: after the previously contributed id within the same contribution method.

Specified by:

add in interface OrderedConfiguration<T>

Parameters:

id - a unique id for the object; the id will be fully qualified with the contributing module's id

object - to add to the service's configuration

constraints - used to order the object relative to other contributed objects

override

public void override(String id,
                     T object,
                     String... constraints)

Description copied from interface: OrderedConfiguration

Overrides a normally contributed object. Each override must match a single normally contributed object.

Specified by:

override in interface OrderedConfiguration<T>

Parameters:

id - identifies object to override

object - overriding object (may be null)

constraints - constraints for the overridden object, replacing constraints for the original object (even if omitted, in which case the override object will have no ordering constraints)

addInstance

public void addInstance(String id,
                        Class<? extends T> clazz,
                        String... constraints)

Description copied from interface: OrderedConfiguration

Adds an ordered object by instantiating (with dependencies) the indicated class. When the configuration type is an interface and the class to be contributed is a local file, then a reloadable proxy for the class will be created and contributed.

Specified by:

addInstance in interface OrderedConfiguration<T>

Parameters:

id - of contribution (used for ordering)

clazz - class to instantiate

constraints - used to order the object relative to other contributed objects

overrideInstance

public void overrideInstance(String id,
                             Class<? extends T> clazz,
                             String... constraints)

Description copied from interface: OrderedConfiguration

Instantiates an object and adds it as an override. When the configuration type is an interface and the class to be contributed is a local file, then a reloadable proxy for the class will be created and contributed.

Specified by:

overrideInstance in interface OrderedConfiguration<T>

Parameters:

id - of object to override

clazz - to instantiate

constraints - constraints for the overridden object, replacing constraints for the original object (even if omitted, in which case the override object will have no ordering constraints)
