Method Detail

createClassLoader

public BundleClassLoader createClassLoader(ClassLoaderDelegate delegate,
                                  BundleProtectionDomain domain,
                                  String[] bundleclasspath)

Description copied from class: BaseData

This method calls all the configured class loading hooks ClassLoadingHook.createClassLoader(ClassLoader, ClassLoaderDelegate, BundleProtectionDomain, BaseData, String[]) methods until on returns a non-null value. If none of the class loading hooks returns a non-null value then the default classloader implementation is used.

Specified by:

createClassLoader in interface BundleData

Overrides:

createClassLoader in class BaseData

Parameters:

delegate - The ClassLoaderDelegate to delegate to.

domain - The BundleProtectionDomain to use when defining a class.

bundleclasspath - An array of bundle classpaths to use to create this classloader. This is specified by the Bundle-ClassPath manifest entry.

Returns:

The new ClassLoader for the BundleData.

See Also:

BundleData.createClassLoader(ClassLoaderDelegate, BundleProtectionDomain, String[])

createGenerationDir

public File createGenerationDir()

findLibrary

public String findLibrary(String libname)

Description copied from class: BaseData

This method calls each configured classloading hook ClassLoadingHook.findLibrary(BaseData, String) method until the first one returns a non-null value.

Specified by:

findLibrary in interface BundleData

Overrides:

findLibrary in class BaseData

Parameters:

libname - The name of the library to find the absolute path to.

Returns:

The absolute path name of the native library or null if the library does not exist.

See Also:

BundleData.findLibrary(String)

installNativeCode

public void installNativeCode(String[] nativepaths)
                       throws BundleException

Description copied from interface: BundleData

Installs the native code paths for this BundleData. Each element of nativepaths must be installed for lookup when findLibrary is called.

Specified by:

installNativeCode in interface BundleData

Overrides:

installNativeCode in class BaseData

Parameters:

nativepaths - The array of native code paths to install for the bundle.

Throws:

BundleException

getStartLevel

public int getStartLevel()

Description copied from interface: BundleData

Returns the start level metadata for this BundleData.

Specified by:

getStartLevel in interface BundleData

Overrides:

getStartLevel in class BaseData

Returns:

the start level metadata for this BundleData.

getStatus

public int getStatus()

Description copied from interface: BundleData

Returns the status metadata for this BundleData. A value of 1 indicates that this bundle is started persistently. A value of 0 indicates that this bundle is not started persistently.

Specified by:

getStatus in interface BundleData

Overrides:

getStatus in class BaseData

Returns:

the status metadata for this BundleData.

save

public void save()

Description copied from interface: BundleData

Persistently stores all the metadata for this BundleData

Specified by:

save in interface BundleData

Overrides:

save in class BaseData
