Prima::Const(3)

NAME
Prima::Const - predefined constants

DESCRIPTION
"Prima::Const" and Prima::Classes is a minimal set of perl modules needed for the toolkit. Since the module provides bindings for the core constants, it is required to be included in every Prima-related module and program.

The constants are assembled under the top-level package names, with no "Prima::" prefix. This violates the perl guidelines about package naming, however, it was considered way too inconvenient to prefix every constant with "Prima::" string.

This document provides description of all core-coded constants. The constants are also described in the articles together with the corresponding methods and properties. For example, "nt" constants are also described in "Flow" in Prima::Object article.
