Class AdminPermission

java.lang.Object
java.security.Permission
oracle.security.jazn.policy.AdminPermission

All Implemented Interfaces:

java.security.Guard, java.io.Serializable

public class AdminPermission

extends java.security.Permission

This class represents the right to administer a permission. <p/> Given a Permission p, the grantee of AdminPermission(p) is granted the right to: <p/>

• grant/revoke permissions implied by p (say p')
• grant/revoke AdminPermission(p')

<p/> For examples: <p/> p = java.io.FilePermission("/home/scott/-","read,write"); <p/> if grantee SCOTT is granted AdminPermission(p),
then SCOTT is granted the following rights: <p/>

• the right to further grant/revoke p' (i.e. read and write privileges for any file(s) in the file system under "/home/scott") to/from other grantees
• the right to further grant/revoke AdminPermission(p')

<p/> Notes: <p/>

• An AdminPermission embedding another AdminPermission is not supported. There is furthermore no need to do so since granting a grantee AdminPermission(p) implies that the grantee can further grant/revoke AdminPermission(p')
• Granting a grantee AdminPermission(p) does not imply granting the grantee p - that needs to be granted separately.

a hash code value for this object.

equals

public boolean equals(java.lang.Object o)

Checks two AdminPermission objects for equality. Checks that obj's class is the same as this object's class and has the same embedded permission as this object.

true if obj is an AdminPermission, and has the same embedded permission as this AdminPermission object, false otherwise.

getEmbeddedPermission
