BundlePermission back to summary

BundlePermission	back to summary
public BundlePermission(String symbolicName, String actions) Defines the authority to provide and/or require and or specify a host fragment symbolic name within the OSGi environment. Bundle Permissions are granted over all possible versions of a bundle. A bundle that needs to provide a bundle must have the appropriate `BundlePermission` for the symbolic name; a bundle that requires a bundle must have the appropriate `BundlePermssion` for that symbolic name; a bundle that specifies a fragment host must have the appropriate `BundlePermission` for that symbolic name. Parameters symbolicName:String The bundle symbolic name. actions:String `provide`,`require`, `host`, `fragment` (canonical order).

public BundlePermission(String symbolicName, String actions)

Defines the authority to provide and/or require and or specify a host fragment symbolic name within the OSGi environment.

Parameters

symbolicName:String: The bundle symbolic name.
actions:String: provide,require, host, fragment (canonical order).

equals back to summary

equals	back to summary
public boolean equals(Object obj) Overrides java.security.BasicPermission.equals. Determines the equality of two `BundlePermission` objects. This method checks that specified bundle has the same bundle symbolic name and `BundlePermission` actions as this `BundlePermission` object. Parameters obj:Object The object to test for equality with this `BundlePermission` object. Returns:boolean `true` if `obj` is a `BundlePermission`, and has the same bundle symbolic name and actions as this `BundlePermission` object; `false` otherwise. Annotations @Override

Returns:boolean

true if obj is a BundlePermission, and has the same bundle symbolic name and actions as this BundlePermission object; false otherwise.

implies back to summary

implies	back to summary
public boolean implies(Permission p) Overrides java.security.BasicPermission.implies. Determines if the specified permission is implied by this object.

The permission to provide a bundle implies the permission to require the named symbolic name.

      x.y.*,"provide" -> x.y.z,"provide" is true
      *,"require" -> x.y, "require"      is true
      *,"provide" -> x.y, "require"      is true
      x.y,"provide" -> x.y.z, "provide"  is false
