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

getComponentName

public java.lang.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.

getFilter

public java.lang.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.

getInterface

public java.lang.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.

getReferenceListeners

public java.util.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.
