Class defining debugging messages.
Allows define assert, warning etc. either only for debug mode or for release mode also.
Definition of asserts is designed using macros FEAL_ASSERT and FEAL_ASSERT_PERMANENT. First macro is used for both modes, second is only for debug. Definition allows to printout given variables too. For simplifying are designed shorter names of macros ASSERT and ASSERT_PERMANENT, these names can be used if thea aren't in conflicts with external libraries.
Examples of usage:
1) We expect empty stings 's1' and 's2', if condition is not satisfied exception will be thrown. Condition is indicated in first parentheses, variables designed for printout follow as (s1)(s2). Each variable must be defined in separate parentheses. The last step is calling of the appropriate assert type, in this case error(). This assert is performed for debug and release mode.
2) Parameter of error method is optional.
3) This example is same as previous, but assert is performed only for debug mode.
4) Example is same as case 1). Assert type error is called automatically if any other is not listed. This case is not recommended, rather use explicitly calling of error() method.
5) Example with same condition as all previous but with other type - warning. Any exception is not thrown, only warning is printed. Parameter of warning method is optional.
For simplifying we have defined several macros for comparsion of values:
All macros allow easier declaration of assert. Following example shows declarations of same cases with usage of different macros:
