Class declaration :

public final class ManagementPermission
extends BasicPermission

Constructor:

Permission(String name)

public Permission(String name): Constructs a new Permission object with this name.

1.public void checkGuard(Object object): It is used to determine if this Permission object can be guarded (protect access to another object) or not.

Parameters:
object - the object to guard.
Throws:
SecurityException - if the access is denied by checkPermission method.

2.public abstract boolean implies(Permission permission): It checks whether this ManagementPermssion object implies this permission or not.

Parameters:
permission - the permission to check against.
Returns:
true if this permission is implied by this object, false otherwise.

3.public abstract boolean equals(Object obj): It checks whether two Permission objects are equal or not.

Parameters:
obj - the object to be compared
Returns:
true if both Permission objects are equal, false otherwise.

4.public abstract int hashCode(): It returns the hash code value for this Permission object.

Returns:
a hash code value for this object.

5.public final String getName(): It returns the name of this Permission.

Returns:
the name of this Permission.

6.public abstract String getActions(): It returns the actions of this Permission object in String format.

Returns:
the actions of this Permission.

7.public PermissionCollection newPermissionCollection(): It returns a new PermissionCollection object.

Returns:
