Public Member Functions
plMap< plString, FileData >::ConstIterator	Lookup (const plString &sFileName) const
	Checks whether sFileName is already in the cache, returns an iterator to it. If the iterator is invalid, the file is not cached yet.
void	Remove (const plString &sFileName)
	Removes the cached content for sFileName from the cache. Should be used when the file content has changed and needs to be re-read.
void	Clear ()
	Removes all files from the cache to ensure that they will be re-read.
const plTokenizer *	Tokenize (const plString &sFileName, plArrayPtr< const plUInt8 > fileContent, const plTimestamp &fileTimeStamp, plLogInterface *pLog)
	Stores FileContent for the file sFileName as the new cached data.

Detailed Description

This object caches files in a tokenized state. It can be shared among plPreprocessor instances to improve performance when they access the same files.

Tokenize()

const plTokenizer * plTokenizedFileCache::Tokenize	(	const plString &	sFileName,
		plArrayPtr< const plUInt8 >	fileContent,
		const plTimestamp &	fileTimeStamp,
		plLogInterface *	pLog )

Stores FileContent for the file sFileName as the new cached data.

The file content is tokenized first and all #line directives are evaluated, to update the line number and file origin for each token. Any errors are written to the given log.
