/// Macro utilities for assertions and debug-only code.
|
|
///
|
|
/// Defines three levels of assertions: debug, development, and release. By
|
|
/// default, if NDEBUG is defined the level is set to development, otherwise is
|
|
/// set to debug.
|
|
///
|
|
/// The following macros are defined here:
|
|
///
|
|
/// * DEBUG_ONLY(code) - Code is evaluated only if assertion level is set to
|
|
/// debug.
|
|
///
|
|
/// * DEVELOPMENT_ONLY(code) - Code is evaluated only if assertion level is
|
|
/// set to development or higher.
|
|
///
|
|
/// * DEBUG_ASSERT(predicate) - Effectively calls assert(predicate).
|
|
///
|
|
/// * DEVELOPMENT_ASSERT(predicate) - Throws an exception if assertion is
|
|
/// set to development or higher, and predicate evaluates to false.
|
|
///
|
|
/// * RELEASE_ASSERT(predicate) - Throws an exception if predicate evaluates
|
|
/// to false.
