Class TargetedPID

java.lang.Object

org.apache.felix.scr.impl.metadata.TargetedPID

public class TargetedPID

Method Detail

getBundleVersion

public static String getBundleVersion(org.osgi.framework.Bundle bundle)

Returns the bundle's version as required for targeted PIDs: If the bundle has a version the string representation of the version string converted to a Version object is returned. Otherwise the string representation of Version.emptyVersion is returned.

Parameters:

bundle - The bundle whose version is to be returned.

matchesTarget

public boolean matchesTarget(org.osgi.framework.Bundle serviceBundle)

Returns true if the target of this PID (bundle symbolic name, version, and location) match the bundle registering the referenced service.

This method just checks the target not the PID value itself, so this method returning true does not indicate whether the service actually is registered with a service PID equal to the raw PID of this targeted PID.

This method also returns false if the service has concurrently been unregistered and the registering bundle is now null.

Parameters:

serviceBundle - Bundle to the registered service

Returns:

true if the referenced service matches the target of this PID.

getRawPid

public String getRawPid()

Gets the raw PID with which this instance has been created.

If an actual service PID contains pipe symbols that PID might be considered being targeted PID without it actually being one. This method provides access to the raw PID to allow for such services to be configured.

getServicePid

public String getServicePid()

Returns the service PID of this targeted PID which basically is the targeted PID without the targeting information.

bindsStronger

public boolean bindsStronger(TargetedPID other)

Returns true if this targeted PID binds stronger than the other TargetedPID.

This method assumes both targeted PIDs have already been checked for suitability for the bundle encoded in the targetting.

Parameters:

other - The targeted PID to check whether it is binding stronger or not.

Returns:

true if the other targeted PID is binding strong.
