◆ TokenHexString()

TokenHexString::TokenHexString ( const std::string & str )

Value is set during token construction.

Parameters

str	constant string to be represented (must be "0x" or "0X" followed by a string of hexadecimal digits or decoding will fail)

◆ evaluate()

unsigned TokenHexString::evaluate	(	Pkt &	pkt,
		ValueStack &	values )

virtual

Token evaluation (puts value of the constant string on the stack after decoding or an empty string if decoding fails (note it should not if the parser is correct)

Parameters

pkt	(ignored)
values	(represented string will be pushed here)

Returns: 0 which means evaluate next token if any.
