jdk.security.acl.AclEntry — clojure-interop/java.security 1.0.5

This is the interface used for representing one entry in an Access Control List (ACL).

An ACL can be thought of as a data structure with multiple ACL entry objects. Each ACL entry object contains a set of permissions associated with a particular principal. (A principal represents an entity such as an individual user or a group). Additionally, each ACL entry is specified as being either positive or negative. If positive, the permissions are to be granted to the associated principal. If negative, the permissions are to be denied. Each principal can have at most one positive ACL entry and one negative entry; that is, multiple positive or negative ACL entries are not allowed for any principal.

Note: ACL entries are by default positive. An entry becomes a negative entry only if the setNegativePermissions method is called on it.

add-permission clj

(add-permission this permission)

Adds the specified permission to this ACL entry. Note: An entry can have multiple permissions.

permission - the permission to be associated with the principal in this entry. - java.security.acl.Permission

returns: true if the permission was added, false if the permission was already part of this entry's permission set. - boolean

check-permission clj

(check-permission this permission)

Checks if the specified permission is part of the permission set in this entry.

permission - the permission to be checked for. - java.security.acl.Permission

returns: true if the permission is part of the permission set in this entry, false otherwise. - boolean

clone clj

(clone this)

Clones this ACL entry.

returns: a clone of this ACL entry. - java.lang.Object

get-principal clj

(get-principal this)

Returns the principal for which permissions are granted or denied by this ACL entry. Returns null if there is no principal set for this entry yet.

returns: the principal associated with this entry. - java.security.Principal

negative? clj

(negative? this)

Returns true if this is a negative ACL entry (one denying the associated principal the set of permissions in the entry), false otherwise.

returns: true if this is a negative ACL entry, false if it's not. - boolean

permissions clj

(permissions this)

Returns an enumeration of the permissions in this ACL entry.

returns: an enumeration of the permissions in this ACL entry. - java.util.Enumeration<java.security.acl.Permission>

remove-permission clj

(remove-permission this permission)

Removes the specified permission from this ACL entry.

permission - the permission to be removed from this entry. - java.security.acl.Permission

returns: true if the permission is removed, false if the permission was not part of this entry's permission set. - boolean

set-negative-permissions clj

(set-negative-permissions this)

Sets this ACL entry to be a negative one. That is, the associated principal (e.g., a user or a group) will be denied the permission set specified in the entry.

Note: ACL entries are by default positive. An entry becomes a negative entry only if this setNegativePermissions method is called on it.

set-principal clj

(set-principal this user)

Specifies the principal for which permissions are granted or denied by this ACL entry. If a principal was already set for this ACL entry, false is returned, otherwise true is returned.

user - the principal to be set for this entry. - java.security.Principal

returns: true if the principal is set, false if there was already a principal set for this entry. - boolean

to-string clj

(to-string this)

Returns a string representation of the contents of this ACL entry.

returns: a string representation of the contents. - java.lang.String
