Class DeploymentCustomizerPermission

java.lang.Object

java.security.Permission

org.osgi.service.deploymentadmin.spi.DeploymentCustomizerPermission

All Implemented Interfaces:

Serializable, Guard

public class DeploymentCustomizerPermission
extends Permission

The DeploymentCustomizerPermission permission gives the right to Resource Processors to access a bundle's (residing in a Deployment Package) private area. The bundle and the Resource Processor (customizer) have to be in the same Deployment Package.

The Resource Processor that has this permission is allowed to access the bundle's private area by calling the DeploymentSession.getDataFile(Bundle) method during the session (see DeploymentSession). After the session ends the FilePermissions are withdrawn. The Resource Processor will have FilePermission with "read", "write" and "delete" actions for the returned File that represents the base directory of the persistent storage area and for its subdirectories.

The actions string is converted to lowercase before processing.

Constructor Detail

DeploymentCustomizerPermission

public DeploymentCustomizerPermission(String name,
                              String actions)

Creates a new DeploymentCustomizerPermission object for the given name and action.

The name parameter is a filter string. This filter has the same syntax as an OSGi filter but only the "name" attribute is allowed. The value of the attribute is a Bundle Symbolic Name that represents a bundle. The only allowed action is the "privatearea" action. E.g.

 Permission perm = new DeploymentCustomizerPermission(
     "(name=com.acme.bundle)", "privatearea");
 

The Resource Processor that has this permission is allowed to access the bundle's private area by calling the DeploymentSession.getDataFile(Bundle) method. The Resource Processor will have FilePermission with "read", "write" and "delete" actions for the returned File and its subdirectories during the deployment session.

Parameters:

name - Bundle Symbolic Name of the target bundle, must not be null.

actions - action string (only the "privatearea" or "*" action is valid; "*" means all the possible actions), must not be null.

Throws:

IllegalArgumentException - if the filter is invalid, the list of actions contains unknown operations or one of the parameters is null

Method Detail

equals

public boolean equals(Object obj)

Checks two DeploymentCustomizerPermission objects for equality. Two permission objects are equal if:

• their target filters are equal (semantically and not character by character) and
• their actions are the same

Specified by:

equals in class Permission

Parameters:

obj - the reference object with which to compare.

Returns:

true if the two objects are equal.

See Also:

Object.equals(java.lang.Object)

hashCode

public int hashCode()

Returns hash code for this permission object.

Specified by:

hashCode in class Permission

Returns:

Hash code for this permission object.

See Also:

Object.hashCode()

getActions

public String getActions()

Returns the String representation of the action list.

Specified by:

getActions in class Permission

Returns:

Action list of this permission instance. It is always "privatearea".

See Also:

Permission.getActions()

implies

public boolean implies(Permission permission)

Checks if this DeploymentCustomizerPermission would imply the parameter permission. This permission implies another DeploymentCustomizerPermission permission if:

• both of them has the "privatearea" action (other actions are not allowed) and
• their filters (only name attribute is allowed in the filters) match similarly to DeploymentAdminPermission.

The value of the name attribute means Bundle Symbolic Name and not Deployment Package Symbolic Name here!

Specified by:

implies in class Permission

Parameters:

permission - Permission to check.

Returns:

true if this DeploymentCustomizerPermission object implies the specified permission.

See Also:

Permission.implies(java.security.Permission)

newPermissionCollection

public PermissionCollection newPermissionCollection()

Returns a new PermissionCollection object for storing DeploymentCustomizerPermission objects.

Overrides:

newPermissionCollection in class Permission

Returns:

The new PermissionCollection.

Permission.newPermissionCollection()
