public ContextAwareComponentFactory(AzkarraContext context,
                                    ComponentFactory factory)

Creates a new ContextAwareComponentFactory instance.

Parameters:

context - the AzkarraContext.

Method Detail

getComponent

public <T> T getComponent(Class<T> type,
                          Conf conf)

Gets an instance, which may be shared or independent, for the specified type.

Specified by:

getComponent in interface ComponentFactory

Overrides:

getComponent in class DelegatingComponentFactory

Type Parameters:

T - the component-type.

Parameters:

type - the component class.

conf - the configuration used if the component implement Configurable.

Returns:

the instance of type ComponentFactory.

getComponent

public <T> T getComponent(Class<T> type,
                          Conf conf,
                          Qualifier<T> qualifier)

Gets an instance, which may be shared or independent, for the specified type.

Specified by:

getComponent in interface ComponentFactory

Overrides:

getComponent in class DelegatingComponentFactory

Type Parameters:

T - the component-type.

Parameters:

type - the component class.

conf - the configuration used if the component implement Configurable.

qualifier - the options used to qualify the component.

Returns:

the instance of type ComponentFactory.

getComponent

public <T> T getComponent(String alias,
                          Conf conf)

Gets an instance, which may be shared or independent, for the specified type. If the object, returned from that method, implements the Configurable interface, then the factory will invoke the method Configurable.configure(Conf) with the given Conf. For a shared object, the method will be invoked only the first time it is returned.

Specified by:

getComponent in interface ComponentFactory

Overrides:

getComponent in class DelegatingComponentFactory

Type Parameters:

T - the component-type.

Parameters:

alias - the fully qualified class name or an alias of the component.

conf - the configuration used if the component implement Configurable.

Returns:

the instance of type ComponentFactory.

getComponent

public <T> T getComponent(String alias,
                          Conf conf,
                          Qualifier<T> qualifier)

Gets an instance, which may be shared or independent, for the specified type. If the object, returned from that method, implements the Configurable interface, then the factory will invoke the method Configurable.configure(Conf) with the given Conf. For a shared object, the method will be invoked only the first time it is returned.

Specified by:

getComponent in interface ComponentFactory

Overrides:

getComponent in class DelegatingComponentFactory

Type Parameters:

T - the component-type.

Parameters:

alias - the fully qualified class name or an alias of the component.

conf - the configuration used if the component implement Configurable.

qualifier - the options used to qualify the component.

Returns:

the instance of type ComponentFactory.

getAllComponents

public <T> Collection<T> getAllComponents(String alias,
                                          Conf conf)

Gets all instances, which may be shared or independent, for the specified type. If one of the objects, returned from that method, implements the Configurable interface, then the factory will invoke the method Configurable.configure(Conf) with the given Conf. For a shared object, the method will be invoked only the first time it is returned.

Specified by:

getAllComponents in interface ComponentFactory

Overrides:

getAllComponents in class DelegatingComponentFactory

Type Parameters:

T - the component-type.

Parameters:

alias - the fully qualified class name or an alias of the component.

conf - the configuration used if the component implement Configurable.

Returns:

all instances of type ComponentFactory.

getAllComponents

public <T> Collection<T> getAllComponents(String alias,
                                          Conf conf,

Gets all instances, which may be shared or independent, for the specified type. If one of the objects, returned from that method, implements the Configurable interface, then the factory will invoke the method Configurable.configure(Conf) with the given Conf.

                                          Conf conf)

Gets all instances, which may be shared or independent, for the specified type. If one of the objects, returned from that method, implements the Configurable interface, then the factory will invoke the method Configurable.configure(Conf) with the given Conf.
