org.orekit.files.ccsds.utils.parsing.AbstractConstituentParser<T,P>

Type Parameters:

T - type of the file

P - type of the parser

All Implemented Interfaces:

MessageParser<T>

Direct Known Subclasses:

public abstract class AbstractConstituentParser<T extends NdmConstituent<?,?>,P extends AbstractConstituentParser<T,?>>
extends AbstractMessageParser<T>

Parser for CCSDS messages.

Note than starting with Orekit 11.0, CCSDS message parsers are mutable objects that gather the data being parsed, until the message is complete and the parseMessage method has returned. This implies that parsers should not be used in a multi-thread context. The recommended way to use parsers is to either dedicate one parser for each message and drop it afterwards, or to use a single-thread loop.

Since:

11.0
