jdk.security.ProtectionDomain — clojure-interop/java.security 1.0.4

The ProtectionDomain class encapsulates the characteristics of a domain, which encloses a set of classes whose instances are granted a set of permissions when being executed on behalf of a given set of Principals.

A static set of permissions can be bound to a ProtectionDomain when it is constructed; such permissions are granted to the domain regardless of the Policy in force. However, to support dynamic security policies, a ProtectionDomain can also be constructed such that it is dynamically mapped to a set of permissions by the current Policy whenever a permission is checked.

->protection-domain clj

(->protection-domain codesource permissions)

(->protection-domain codesource permissions classloader principals)

Constructor.

Creates a new ProtectionDomain qualified by the given CodeSource, Permissions, ClassLoader and array of Principals. If the permissions object is not null, then setReadOnly() will be called on the passed in Permissions object. The permissions granted to this domain are dynamic; they include both the static permissions passed to this constructor, and any permissions granted to this domain by the current Policy at the time a permission is checked.

This constructor is typically used by ClassLoaders and DomainCombiners which delegate to Policy to actively associate the permissions granted to this domain. This constructor affords the Policy provider the opportunity to augment the supplied PermissionCollection to reflect policy changes.

codesource - the CodeSource associated with this domain - java.security.CodeSource permissions - the permissions granted to this domain - java.security.PermissionCollection classloader - the ClassLoader associated with this domain - java.lang.ClassLoader principals - the array of Principals associated with this domain. The contents of the array are copied to protect against subsequent modification. - java.security.Principal[]

get-class-loader clj

(get-class-loader this)

Returns the ClassLoader of this domain.

returns: the ClassLoader of this domain which may be null. - java.lang.ClassLoader

get-code-source clj

(get-code-source this)

Returns the CodeSource of this domain.

returns: the CodeSource of this domain which may be null. - java.security.CodeSource

get-permissions clj

(get-permissions this)

Returns the static permissions granted to this domain.

returns: the static set of permissions for this domain which may be null. - java.security.PermissionCollection

get-principals clj

(get-principals this)

Returns an array of principals for this domain.

returns: a non-null array of principals for this domain. Returns a new array each time this method is called. - java.security.Principal[]

implies clj

(implies this permission)

Check and see if this ProtectionDomain implies the permissions expressed in the Permission object.

The set of permissions evaluated is a function of whether the ProtectionDomain was constructed with a static set of permissions or it was bound to a dynamically mapped set of permissions.

If the ProtectionDomain was constructed to a statically bound PermissionCollection then the permission will only be checked against the PermissionCollection supplied at construction.

However, if the ProtectionDomain was constructed with the constructor variant which supports dynamically binding permissions, then the permission will be checked against the combination of the PermissionCollection supplied at construction and the current Policy binding.

permission - the Permission object to check. - java.security.Permission

returns: true if permission is implicit to this ProtectionDomain. - boolean

to-string clj

(to-string this)

Convert a ProtectionDomain to a String.

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