Class ContextBinding

java.lang.Object

org.orekit.files.ccsds.utils.ContextBinding

public class ContextBinding
extends Object

Context for parsing/writing Navigation Data Message.

This class is a facade providing late binding access to data. Late binding is mainly useful at parse time as it allows some data to be set up during parsing itself. This is used for example to access time system that is generally parsed from metadata block, and used later on within the same metadata block.
