alib::boxing::FIsTrue Struct Reference

Description:

This is one of the built-in box-functions of ALib Boxing. This function is used to give an answer to the question if a boxed value represents a boolean value true or false. This is useful if "yes/no" decisions should be taken based on arbitrary boxed values.

A default implementation is registered which for non-array types just interprets the first integral value in the Placeholder: If it is not 0, true is returned, false otherwise.
For array types, the default implementation returns true if method Box::UnboxLength returns a value different to 0, otherwise false is returned.
