All Implemented Interfaces:

public final class EndpointPermission
extends java.security.Permission

A bundle's authority to export, import or read an Endpoint.

Permission to read an Endpoint is required in order to detect events regarding an Endpoint. Untrusted bundles should not be able to detect the presence of certain Endpoints unless they have the appropriate EndpointPermission to read the specific service.

Constructor Detail

EndpointPermission

public EndpointPermission(java.lang.String filterString,
                          java.lang.String actions)
Create a new EndpointPermission with the specified filter.

The filter will be evaluated against the endpoint properties of a requested EndpointPermission.

There are three possible actions: read, import and export. The read action allows the owner of this permission to see the presence of distributed services. The import action allows the owner of this permission to import an endpoint. The export action allows the owner of this permission to export a service.

Parameters:
filterString - The filter string or "*" to match all endpoints.
actions - The actions read, import, or export.
Throws:
java.lang.IllegalArgumentException - If the filter has an invalid syntax or the actions are not valid.

EndpointPermission

public EndpointPermission(EndpointDescription endpoint,
                          java.lang.String localFrameworkUUID,
                          java.lang.String actions)
Creates a new requested EndpointPermission object to be used by code that must perform checkPermission. EndpointPermission objects created with this constructor cannot be added to an EndpointPermission permission collection.

Parameters:
endpoint - The requested endpoint.
localFrameworkUUID - The UUID of the local framework. This is used to support matching the endpoint.framework.uuid endpoint property to the <<LOCAL>> value in the filter expression.
actions - The actions read, import, or export.
Throws:
java.lang.IllegalArgumentException - If the endpoint is null or the actions are not valid.
Method Detail

implies

public boolean implies(java.security.Permission p)
Determines if a EndpointPermission object "implies" the specified permission.

Specified by:
implies in class java.security.Permission
Parameters:
p - The target permission to check.
Returns:
true if the specified permission is implied by this object; false otherwise.

getActions

public java.lang.String getActions()
Returns the canonical string representation of the actions. Always returns present actions in the following canonical order: read, import, export.

Specified by:
getActions in class java.security.Permission
Returns:
The canonical string representation of the actions.

newPermissionCollection

public java.security.PermissionCollection newPermissionCollection()
Returns a new PermissionCollection object for storing EndpointPermission objects.

Overrides:
newPermissionCollection in class java.security.Permission
Returns:
A new PermissionCollection object suitable for storing EndpointPermission objects.

equals

public boolean equals(java.lang.Object obj)
Determines the equality of two EndpointPermission objects. Checks that specified object has the same name, actions and endpoint as this EndpointPermission.

Specified by:
equals in class java.security.Permission
Parameters:
obj - The object to test for equality.
Returns:
true If obj is a EndpointPermission, and has the same name, actions and endpoint as this EndpointPermission object; false otherwise.

hashCode

public int hashCode()
Returns the hash code value for this object.

Specified by:
hashCode in class java.security.Permission
Returns:
Hash code value for this object.
