Class CPFWriter

java.lang.Object

org.orekit.files.ilrs.CPFWriter

All Implemented Interfaces:

EphemerisFileWriter

public class CPFWriter
extends Object
implements EphemerisFileWriter

An CPF Writer class that can take in a general EphemerisFile object and export it as a valid CPF file.

It supports both 1.0 and 2.0 versions

Note: By default, only required header keys are wrote (H1 and H2). Furthermore, only position data can be written. Other keys (i.e. in header and other types of ephemeris entries) are simply ignored. Contributions are welcome to support more fields in the format.

Since:

10.3

write

public <C extends TimeStampedPVCoordinates,S extends EphemerisFile.EphemerisSegment<C>> void write(Appendable writer,
                                                                                                   EphemerisFile<C,S> ephemerisFile)

Write the passed in EphemerisFile using the passed in Appendable.

Specified by:

write in interface EphemerisFileWriter

Type Parameters:

C - type of the Cartesian coordinates

S - type of the segment

Parameters:

writer - a configured Appendable to feed with text

ephemerisFile - a populated ephemeris file to serialize into the buffer

Throws:

IOException - if any buffer writing operations fail or if the underlying format doesn't support a configuration in the EphemerisFile (for example having multiple satellites in one file, having the origin at an unspecified celestial body, etc.)
