An installed bundle in the Framework.

 A Bundle object is the access point to define the lifecycle of an installed bundle. Each bundle installed in the OSGi environment must have an associated Bundle object. 
 A bundle must have a unique identity, a long, chosen by the Framework. This identity must not change during the lifecycle of a bundle, even when the bundle is updated. Uninstalling and then reinstalling the bundle must create a new unique identity. 

A bundle can be in one of six states:




Values assigned to these states have no specified ordering; they represent
bit values that may be ORed together to determine if a bundle is in one of
the valid states.

 A bundle should only have active threads of execution when its state is one of STARTING,ACTIVE, or STOPPING. An UNINSTALLED bundle can not be set to another state; it is a zombie and can only be reached because references are kept somewhere. 
 The Framework is the only entity that is allowed to create Bundle objects, and these objects are only valid within the Framework that created them. 
 Bundles have a natural ordering such that if two Bundles have the same bundle id they are equal. A Bundle is less than another Bundle if it has a lower 
bundle id and is greater if it has a higher bundle id.

this bundle's start level, this bundle will be started.


Otherwise, the following steps are required to start this bundle:

    

  1. If this bundle is in the process of being activated or deactivated then this method must wait for activation or deactivation to complete before continuing. If this does not occur in a reasonable time, a BundleException is thrown to indicate this bundle was unable to be started.
    2. 

  2. If the START_TRANSIENT option is not set then set this bundle's autostart setting to Started with declared activation if the START_ACTIVATION_POLICY option is set or Started with eager activation if not set. When the Framework is
restarted and this bundle's autostart setting is not Stopped,
this bundle must be automatically started.
    3. 

  3. If this bundle's state is ACTIVE then this method returns immediately.
    4. 

  4. If this bundle's state is not RESOLVED, an attempt is made to resolve this bundle. If the Framework cannot resolve this bundle, a BundleException is thrown.
    5. 

  5. If the START_ACTIVATION_POLICY option is set and this bundle's declared activation policy is 
lazy then: 
      

    • If this bundle's state is STARTING then this method returns immediately.
      • 

    • This bundle's state is set to STARTING.
      • 

    • A bundle event of type BundleEvent.LAZY_ACTIVATION is fired.

      • 

    

    6. 

  6. This bundle's state is set to STARTING.
    7. 

  7. A bundle event of type BundleEvent.STARTING is fired.
    8. 

  8. The BundleActivator.start(BundleContext) method of this bundle's BundleActivator, if one is specified, is called. If the BundleActivator is invalid or throws an exception then: 
      

    • This bundle's state is set to STOPPING.
      • 

    • A bundle event of type BundleEvent.STOPPING is fired.
      •

Stops this bundle.


The following steps are required to stop a bundle:

    

  1. If this bundle's state is UNINSTALLED then an IllegalStateException is thrown.
    2. 

  2. If this bundle is in the process of being activated or deactivated then this method must wait for activation or deactivation to complete before continuing. If this does not occur in a reasonable time, a BundleException is thrown to indicate this bundle was unable to be stopped.
    3. 

  3. If the STOP_TRANSIENT option is not set then set this bundle's persistent autostart setting to Stopped. When the
Framework is restarted and this bundle's autostart setting is
Stopped, this bundle must not be automatically started.
    4. 

  4. If this bundle's state is not STARTING or ACTIVE then this method returns immediately.
    5. 

  5. This bundle's state is set to STOPPING.
    6. 

  6. A bundle event of type BundleEvent.STOPPING is fired.
    7. 

  7. If this bundle's state was ACTIVE prior to setting the state to STOPPING, the BundleActivator.stop(BundleContext) method of this bundle's BundleActivator, if one is specified, is called. If that method throws an exception, this method must continue to stop this bundle and a BundleException must be thrown after completion of the remaining steps.

Updates this bundle from an InputStream. 
 If the specified InputStream is null, the Framework must create the InputStream from which to read the updated bundle by interpreting, in an implementation dependent manner, this bundle's Bundle-UpdateLocation Manifest header, if present, or this bundle's original location. 
 If this bundle's state is ACTIVE, it must be stopped before the update and started after the update successfully completes. 
 If this bundle has exported any packages that are imported by another bundle, these packages must remain exported until the 
FrameworkWiring.refreshBundles method has been has been called or the Framework is relaunched. 

The following steps are required to update a bundle:

    

  1. If this bundle's state is UNINSTALLED then an IllegalStateException is thrown.
    2. 

  2. If this bundle's state is ACTIVE, STARTING or STOPPING, this bundle is stopped as described in the Bundle.stop method. If Bundle.stop throws an exception, the exception is rethrown terminating the update.
    3. 

  3. The updated version of this bundle is read from the input stream and installed. If the Framework is unable to install the updated version of this bundle, the original version of this bundle must be restored and a BundleException must be thrown after completion of the remaining steps.
    4. 

  4. This bundle's state is set to INSTALLED.
    5. 

  5. If the updated version of this bundle was successfully installed, a bundle event of type BundleEvent.UPDATED is fired.
    6. 

  6. If this bundle's state was originally ACTIVE, the updated bundle is started as described in the Bundle.start method. If Bundle.start throws an exception, a Framework event of type FrameworkEvent.ERROR is fired containing the exception.

Returns this bundle's Manifest headers and values. This method returns
all the Manifest headers and values from the main section of this
bundle's Manifest file; that is, all lines prior to the first blank line.

 Manifest header names are case-insensitive. The methods of the returned Dictionary object must operate on header names in a case-insensitive manner. If a Manifest header value starts with "%", it must be localized according to the default locale. If no localization is found for a header value, the header value without the leading "%" is returned. 

For example, the following Manifest headers and values are included if
they are present in the Manifest file:

    Bundle-Name

Returns this bundle's Manifest headers and values localized to the
specified locale.

 This method performs the same function as Bundle.getHeaders() except the manifest header values are localized to the specified locale. 

If a Manifest header value starts with "%", it must be
localized according to the specified locale. If a locale is specified and
cannot be found, then the header values must be returned using the
default locale. Localizations are searched for in the following order:

  bn + "_" + Ls + "_" + Cs + "_" + Vs
  bn + "_" + Ls + "_" + Cs
  bn + "_" + Ls
  bn + "_" + Ld + "_" + Cd + "_" + Vd
  bn + "_" + Ld + "_" + Cd
  bn + "_" + Ld
  bn

 Where bn is this bundle's localization basename, Ls, Cs and Vs are the specified locale (language, country, variant) and Ld, Cd and Vd are the default locale (language, country, variant). If null is specified as the locale string, the header values must be localized using the default locale. If the empty string ("") is specified as the locale string, the header values must not be localized and the raw (unlocalized) header values, including any leading "%", must be returned. If no localization is found for a header value, the header value without the leading "%" is returned. 
 This method must continue to return Manifest header information while this bundle is in the UNINSTALLED state, however the header values must only be available in the raw and default locale values. 
Params:
  • locale – The locale name into which the header values are to be localized. If the specified locale is null then the locale returned by java.util.Locale.getDefault is used. If the specified locale is the empty string, this method will return the raw (unlocalized) manifest headers including any leading "%".

Returns entries in this bundle and its attached fragments. This bundle's class loader is not used to search for entries. Only the contents of this bundle and its attached fragments are searched for the specified entries. If this bundle's state is INSTALLED, this method must attempt to resolve this bundle before attempting to find entries. 

This method is intended to be used to obtain configuration, setup,
localization and other information from this bundle. This method takes
into account that the "contents" of this bundle can be extended
with fragments. This "bundle space" is not a namespace with
unique members; the same entry name can be present multiple times. This
method therefore returns an enumeration of URL objects. These URLs can
come from different JARs but have the same path name. This method can
either return only entries in the specified path or recurse into
subdirectories returning entries in the directory tree beginning at the
specified path. Fragments can be attached after this bundle is resolved,
possibly changing the set of URLs returned by this method. If this bundle
is not resolved, only the entries in the JAR file of this bundle are
returned.


Examples:

// List all XML files in the OSGI-INF directory and below
Enumeration e = b.findEntries("OSGI-INF", "*.xml", true);
// Find a specific localization file
Enumeration e = b.findEntries("OSGI-INF/l10n",
    "bundle_nl_DU.properties", false);
if (e.hasMoreElements())
    return (URL) e.nextElement();




URLs for directory entries must have their path end with "/".


Note: Jar and zip files are not required to include directory entries.
URLs to directory entries will not be returned if the bundle contents do
not contain directory entries.

Params:
  • path – The path name in which to look. The path is always relative
       to the root of this bundle and may begin with "/". A
       path value of "/" indicates the root of this bundle.
  • filePattern – The file name pattern for selecting entries in the
       specified path. The pattern is only matched against the last
       element of the entry path. If the entry is a directory then the
       trailing "/" is not used for pattern matching. Substring
       matching is supported, as specified in the Filter specification,
       using the wildcard character ("*"). If null is
       specified, this is equivalent to "*" and matches all
       files.
  • recurse – If true, recurse into subdirectories. Otherwise only return entries from the specified path.
Throws:

Return the certificates for the signers of this bundle and the
certificate chains for those signers.

Params:
  • signersType – If SIGNERS_ALL is specified, then information on all signers of this bundle is returned. If SIGNERS_TRUSTED is specified, then only information on the signers of this bundle trusted by the framework is returned.
Throws:
Returns:The X509Certificates for the signers of this bundle and the X509Certificate chains for those signers. The keys of the Map are the X509Certificates of the signers of this bundle. The value for a key is a List containing the X509Certificate chain for the signer. The first item in the List is the signer's X509Certificate which is then followed by the rest of the X509Certificate chain. The returned Map will be empty if there are no signers. The returned Map is the property of the caller who is free to modify it.

Adapt this bundle to the specified type.

 Adapting this bundle to the specified type may require certain checks, including security checks, to succeed. If a check does not succeed, then this bundle cannot be adapted and null is returned. 
Params:
  • type – Class object for the type to which this bundle is to be
       adapted.
Type parameters:
  • <A> – The type to which this bundle is to be adapted.
Throws:
  • SecurityException – If the caller does not have the appropriate AdaptPermission[type,this,ADAPT], and the Java Runtime Environment supports permissions.
