returns the root node of the valid policy tree resulting from the pkix certification path validation algorithm . the policynode object that is returned and any objects that it returns through public methods are immutable . most applications will not need to examine the valid policy tree . they can achieve their policy processing goals by setting the policy-related parameters in pkixparameters . however , more sophisticated applications , especially those that process policy qualifiers , may need to traverse the valid policy tree using the policynode #getparent policynode.getparent and policynode #getchildren policynode.getchildren methods . concode_field_sep TrustAnchor trustAnchor concode_elem_sep PolicyNode policyTree concode_elem_sep PublicKey subjectPublicKey concode_field_sep TrustAnchor getTrustAnchor concode_elem_sep Object clone concode_elem_sep String toString concode_elem_sep PublicKey getPublicKey
