Detailed Description

This Issue represents a basic assertion.

This class represents an assertion in the code, it is an issue with two fields:

• A condition
• A message describing the condition

If the condition is not verified, an Issue is trown.

build_message() [1/2]

std::string ers::Assertion::build_message ( const char *  condition_text, const std::string &  msg, bool  constant_expression = false  ) throw ( )

protectedvirtual

Builds the message associated with an assertion

Returns

message describing the failure of the assertion

Parameters

condition_text	the condition in textual form
msg	the message associated with the condition
constant_expression	is the assertion a constant expression as detected by the compiler.

Returns

an human readable message
