Examples of java.security.ProtectionDomain.implies()

java.security.ProtectionDomain.implies()

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 {@link #ProtectionDomain(CodeSource,PermissionCollection) statically bound} PermissionCollection then the permission willonly be checked against the PermissionCollection supplied at construction.

However, if the ProtectionDomain was constructed with the constructor variant which supports {@link #ProtectionDomain(CodeSource,PermissionCollection,ClassLoader,java.security.Principal[]) dynamically binding}permissions, then the permission will be checked against the combination of the PermissionCollection supplied at construction and the current Policy binding.

@param permission the Permission object to check. @return true if "permission" is implicit to this ProtectionDomain.
