Method Detail

getAvailability

public int getAvailability()

Description copied from interface: ServiceReferenceMetadata

Return whether or not a matching service is required at all times. This is specified in the availability attribute of the service reference.

Specified by:

getAvailability in interface ServiceReferenceMetadata

Returns:

Whether or not a matching service is required at all times.

See Also:

ServiceReferenceMetadata.AVAILABILITY_MANDATORY, ServiceReferenceMetadata.AVAILABILITY_OPTIONAL

setAvailability

public void setAvailability(int availability)

Specified by:

setAvailability in interface MutableServiceReferenceMetadata

getInterface

public String getInterface()

Description copied from interface: ServiceReferenceMetadata

Return the name of the interface type that a matching service must support. This is specified in the interface attribute of the service reference.

Specified by:

getInterface in interface ServiceReferenceMetadata

Returns:

The name of the interface type that a matching service must support or null when no interface name is specified.

setInterface

public void setInterface(String interfaceName)

Specified by:

setInterface in interface MutableServiceReferenceMetadata

getComponentName

public String getComponentName()

Description copied from interface: ServiceReferenceMetadata

Return the value of the component-name attribute of the service reference. This specifies the id of a component that is registered in the service registry. This will create an automatic filter, appended with the filter if set, to select this component based on its automatic id attribute.

Specified by:

getComponentName in interface ServiceReferenceMetadata

Returns:

The value of the component-name attribute of the service reference or null if the attribute is not specified.

setComponentName

public void setComponentName(String componentName)

Specified by:

setComponentName in interface MutableServiceReferenceMetadata

getFilter

public String getFilter()

Description copied from interface: ServiceReferenceMetadata

Return the filter expression that a matching service must match. This is specified by the filter attribute of the service reference.

Specified by:

getFilter in interface ServiceReferenceMetadata

Returns:

The filter expression that a matching service must match or null if a filter is not specified.

setFilter

public void setFilter(String filter)

Specified by:

setFilter in interface MutableServiceReferenceMetadata

getReferenceListeners

public Collection<ReferenceListener> getReferenceListeners()

Description copied from interface: ServiceReferenceMetadata

Return the reference listeners to receive bind and unbind events. This is specified by the reference-listener elements of the service reference.

Specified by:

getReferenceListeners in interface ServiceReferenceMetadata

Returns:

An immutable Collection of ReferenceListener objects to receive bind and unbind events. The Collection is empty if no reference listeners are specified for the service reference.

setReferenceListeners

public void setReferenceListeners(Collection<ReferenceListener> listeners)

addServiceListener

public void addServiceListener(ReferenceListener bindingListenerMetadata)

Specified by:

addServiceListener in interface MutableServiceReferenceMetadata

addServiceListener

public ReferenceListener addServiceListener(Target listenerComponent,
                                            String bindMethodName,
                                            String unbindMethodName)

Specified by:

addServiceListener in interface MutableServiceReferenceMetadata

removeReferenceListener

public void removeReferenceListener(ReferenceListener listener)

Specified by:

removeReferenceListener in interface MutableServiceReferenceMetadata

getProxyMethod

public int getProxyMethod()

Specified by:

getProxyMethod in interface ExtendedServiceReferenceMetadata

setProxyMethod

public void setProxyMethod(int proxyMethod)

Specified by:

setProxyMethod in interface MutableServiceReferenceMetadata

getRuntimeInterface

public Class getRuntimeInterface()

Specified by:

getRuntimeInterface in interface ExtendedServiceReferenceMetadata

setRuntimeInterface

public void setRuntimeInterface(Class runtimeInterface)

Specified by:

setRuntimeInterface in interface MutableServiceReferenceMetadata
