Detailed Description

This example shows how to:

• Build the gparticle option schema using gparticle::defineOptions()
• Parse command-line options into a GOptions instance
• Create a module logger
• Build a vector of Gparticle objects using gparticle::getGParticles()

Usage example (shell):

./gparticle_example -gparticle="[{name: e-, p: 5000*MeV, theta: 23*deg}]"

Notes:

• This program initializes a G4RunManager and sets a simple physics list.
• The example does not run an event loop; it focuses on configuration parsing and object construction.

Function Documentation

main()

int main	(	int	argc,
		char *	argv[] )

The program performs the following steps:

1. Creates a GOptions instance that includes the gparticle option definitions.
2. Creates a logger for the module (using the GPARTICLE_LOGGER channel).
3. Creates a G4RunManager using the factory API.
4. Installs a minimal physics list (QBBC).
5. Parses the configured particles by calling gparticle::getGParticles().
6. Cleans up the run manager and exits.

Parameters

argc	Number of command-line arguments.
argv	Command-line arguments.

Returns

Process exit code.
