static Derivator* afl::DerivationFactory::derivator (  const Field *  field, const ddf::PropertySet *  pset, const Parameters &  params )  [static]

creates a derivation object Parameters: field  the field the derivator would operate on pset  the numeric data of the field params  paremeters for the derivation object. The parameters need to include "delta-x", "delta-y", "delta-z" and "delta-t" as appropriate for the dimension of the field.

static Derivator* afl::DerivationFactory::derivator (  XMLNode *  derivator, Field *  field, const ddf::PropertySet *  pset )  [static]

create a derivation object from XML. The object needs to have the following child elements: <delta-x&gt;, <delta-y&gt;, <delta-z&gt; and <delta-t&gt; with respect to the dimension of the field. Parameters: derivator  an XML node that describes the derivator in FRL field  the field the derivator will operate on pset  the numeric data of the field Returns: the derivator Exceptions: ddf::ParseException  if the interpolation method is not recognized from the XML or if the XML is malformed.
