Method Detail

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

getUnifiedFilter

public org.osgi.framework.Filter getUnifiedFilter()

Assembles the configuration properties into one unified OSGi filter. Note that this implementation creates the filter on the first call and caches it afterwards.

Returns:

unified filter based on this factory bean configuration

setInterfaces

public void setInterfaces(java.lang.Class<?>[] interfaces)

Sets the classes that the imported service advertises.

Parameters:

interfaces - array of advertised classes.

setContextClassLoader

public void setContextClassLoader(ImportContextClassLoader contextClassLoader)

Deprecated. As of Spring DM 2.0, replaced by #setImportContextClassLoader(ImportContextClassLoaderEnum))

Sets the thread context class loader management strategy to use for services imported by this service. By default ImportContextClassLoader.CLIENT is used.

Parameters:

contextClassLoader - import context class loader management strategy

See Also:

ImportContextClassLoader

setImportContextClassLoader

public void setImportContextClassLoader(ImportContextClassLoaderEnum contextClassLoader)

Sets the thread context class loader management strategy to use for services imported by this service. By default ImportContextClassLoaderEnum.CLIENT is used.

Parameters:

contextClassLoader - import context class loader management strategy

See Also:

ImportContextClassLoader

setBundleContext

public void setBundleContext(org.osgi.framework.BundleContext context)

Description copied from interface: BundleContextAware

Set the BundleContext that this bean runs in. Normally this can be used to initialize an object.

Specified by:

setBundleContext in interface BundleContextAware

Parameters:

context - the BundleContext object to be used by this object

setFilter

public void setFilter(java.lang.String filter)

Sets the OSGi service filter. The filter will be concatenated with the rest of the configuration properties specified (such as interfaces) so there is no need to include them in the filter.

Parameters:

filter - OSGi filter describing the importing OSGi service

setListeners

public void setListeners(OsgiServiceLifecycleListener[] listeners)

Sets the lifecycle listeners interested in receiving events for this importer.

Parameters:

listeners - importer listeners

setServiceBeanName

public void setServiceBeanName(java.lang.String serviceBeanName)

Sets the OSGi service bean name. This setting should be normally used when the imported service has been exported by Spring DM exporter. You may specify additional filtering criteria if needed (using the filter property) but this is not required.

Parameters:

serviceBeanName - importer service bean name

setBeanClassLoader

public void setBeanClassLoader(java.lang.ClassLoader classLoader)

This method is called automatically by the container.

Specified by:

setBeanClassLoader in interface org.springframework.beans.factory.BeanClassLoaderAware

getBeanClassLoader

public java.lang.ClassLoader getBeanClassLoader()

Returns the class loader used by this FactoryBean.

Returns:

factory bean class loader

getBundleContext

public org.osgi.framework.BundleContext getBundleContext()

Returns the bundleContext used by this FactoryBean.

Returns:

factory bean class loader

getInterfaces

public java.lang.Class<?>[] getInterfaces()

Returns the interfaces used for discovering the imported service(s).

Returns:

interfaces advertised by services in the OSGi space

getFilter

public java.lang.String getFilter()

Returns the filter describing the imported service(s).

Returns:

filter describing the imported service(s)

getListeners

public OsgiServiceLifecycleListener[] getListeners()

Returns the listeners interested in receiving events for this importer.

Returns:

lifecycle listeners used by this importer

getContextClassLoader

public ImportContextClassLoader getContextClassLoader()

Deprecated. As of Spring DM 2.0, replaced by getImportContextClassLoader()

Returns the context class loader management strategy.

Returns:

the context class loader management strategy

getImportContextClassLoader

public ImportContextClassLoaderEnum getImportContextClassLoader()

Returns the context class loader management strategy.

Returns:

the context class loader management strategy
