◆ boolean()

bool csspp::expression::boolean ( node::pointer_t  n)
static

This function checks whether a node represents a valid boolean. If so it returns true or false depending on that fact.

If the node does not represent a boolean, then the function returns false after it generated an error.

Note
The function is also used by the conditional() and logical_or() functions.
Parameters
[in]nThe node to check whether it is true or false.
Returns
true or false.
