Member Function Documentation

◆ evaluate()

void TokenOr::evaluate ( Pkt pkt,
ValueStack values 
)
virtual

Logical or.

Evaluation does not use packet information, but rather consumes the last two parameters. It returns "false" if and only if both are "false". It requires at least two logical (i.e., "true" or "false') values present on stack. @throw EvalBadStack if there are less than 2 values on stack @throw EvalTypeError if one of the 2 values on stack is not "true" or "false"

Parameters
pkt(unused)
values- stack of values (2 arguments will be popped, 1 result will be pushed)

Implements isc::dhcp::Token.
