Net (gb.net)

This class provides constant definitions used by the rest of the classes in this component.

Most of them are linked with the Status property of Net classes. In that case:

  • Error values are always negative values.

  • An inactive value is always zero.

  • Activity is reflected with positive values.

You can determine if there was an error, by checking whether the Status property is negative.

This class is static.
