Detailed Description

Defines the "delegating Policy provider" / JACC 2.5 In J2SE 1.4 new methods can be used for dynamic permissions implies() and getPermissions() methods on Policy class were added.

A replacement Policy object may accomplish this by delegating non-javax.security.jacc policy decisions to the corresponding default system Policy implementation class. A replacement Policy object that relies in this way on the corresponding default Policy implementation class must identify itself in its installation instructions as a "delegating Policy provider"

JOnAS uses delegating model

Member Function Documentation

JPolicy org.objectweb.jonas_lib.security.jacc.JPolicy.getInstance (   )  [static]

Gets the unique instance of the JACC delegating policy provider Returns: unique instance of the JACC delegating policy provider Definition at line 132 of file JPolicy.java. References org.objectweb.jonas_lib.security.jacc.JPolicy.JPolicy().

Here is the call graph for this function:

PermissionCollection org.objectweb.jonas_lib.security.jacc.JPolicy.getPermissions (  CodeSource  codeSource  )

Evaluates the global policy and returns a PermissionCollection object specifying the set of permissions allowed for code from the specified code source. Parameters: codeSource  the CodeSource associated with the caller. This encapsulates the original location of the code (where the code came from) and the public key(s) of its signer. Returns: the set of permissions allowed for code from codesource according to the policy.The returned set of permissions must be a new mutable instance and it must support heterogeneous Permission types. Definition at line 312 of file JPolicy.java.

PermissionCollection org.objectweb.jonas_lib.security.jacc.JPolicy.getPermissions (  ProtectionDomain  domain  )

Evaluates the global policy and returns a PermissionCollection object specifying the set of permissions allowed given the characteristics of the protection domain. Parameters: domain  the ProtectionDomain associated with the caller. Returns: the set of permissions allowed for the domain according to the policy.The returned set of permissions must be a new mutable instance and it must support heterogeneous Permission types. Definition at line 279 of file JPolicy.java.

boolean org.objectweb.jonas_lib.security.jacc.JPolicy.implies (  ProtectionDomain  domain, Permission  permission )

Evaluates the global policy for the permissions granted to the ProtectionDomain and tests whether the permission is granted. Parameters: domain  the ProtectionDomain to test. permission  the Permission object to be tested for implication. Returns: true if "permission" is a proper subset of a permission granted to this ProtectionDomain. Definition at line 156 of file JPolicy.java. References org.objectweb.jonas_lib.security.jacc.JPolicyConfiguration.getExcludedPermissions(), org.objectweb.jonas_lib.I18n.getMessage(), and org.objectweb.jonas_lib.security.jacc.JPolicyConfiguration.getUncheckedPermissions().

Here is the call graph for this function:

void org.objectweb.jonas_lib.security.jacc.JPolicy.refresh (   )

Refreshes/reloads the policy configuration. Definition at line 331 of file JPolicy.java.
