Detailed Description

Code used by GEPhysicsCore to evolve according to an ephemeris table. The data values have been repackaged by GECore and converted into GE units by the time this code acts on them.

Member Function Documentation

EphemDataAlloc()

static void GravityEngine2.EphemerisPropagator.EphemDataAlloc ( EphemerisData ephemData, ref GEPhysicsCore::GEPhysicsJob gePhysicsJob, GBUnits::GEScaler geScaler, int centerId, int pIndex )

static

Create a PropInfo instance and fill it in.

Manage the one flat ephemData array used for all ephem propagators. This is sized on demand, so an add forces a grow and a copy.

Implementation assumes adding bodies with ephemeris data is not a common run-time activity.

Parameters

ephemData
gePhysicsJob
geScaler
centerId
pIndex

EphemDataFree()

static void GravityEngine2.EphemerisPropagator.EphemDataFree ( ref GEPhysicsCore::GEPhysicsJob gePhysicsJob, int pIndex )

static

Free the memory in the global flat ephemData array.

This is a klunky, greedy implementation:

• find the entry range
• copy down everything higher

Parameters

gePhysicsJob
pIndex
