Detailed Description

Target implementation wrapping a const Star&.

The referenced Star must outlive the StarTarget. Typically used with the pre-built catalog stars (e.g. VEGA(), SIRIUS()) which are lazy-initialized singletons and live for the entire program.

Examples

05_target_tracking.cpp.

Definition at line 32 of file star_target.hpp.

Constructor & Destructor Documentation

StarTarget()

siderust::StarTarget::StarTarget ( const Star &  star )

inlineexplicit

Wrap a Star reference as a Target.

Parameters

star	Reference to a Star. Must outlive this adapter.

Definition at line 38 of file star_target.hpp.
