상세한 설명

Base class for token scanning strategies

As mentioned in stelaParser, the parser must dynamically change scan mode to precisely measure indentation. tokenScan handles one such scan mode strategy.

Command Tokens

Among tokens exist command tokens like SCAN_AGAIN, SCAN_EXIT that give commands to the scanner or parser. See zztokenType enum in stelaParser.hpp for details.

isBypass

IndentScan ignores most tokens and focuses solely on counting whitespace. However, if multiple tokens were pushed from the previous line, it operates in bypass mode internally. During this time, it skips indentation counting and simply reads and returns the stored tokens.

멤버 함수 문서화

onScan() [1/3]

nint by::stelaTokenScanable::onScan	(	stelaParser &	ps,
		ZZSTYPE *	val,
		ZZLTYPE *	loc,
		zzscan_t	scanner )

Default entry point for token scanning.

This non-virtual method acts as a wrapper that internally dispatches to the pure virtual onScan method, which must be implemented by concrete scanner strategies.
