Declaration

Arguments

Function result

Description

FileExistsCached ensures that a cached item with the name in AFileName has an up-to-date "file exists" flag value in the cache.

Calls Check to use the valid flag value for an existing TFileStateCacheItem instance in the cache. If the return value from Check is True, no additional actions are performed in the method.

Otherwise, the flag value was not present for the specified cache item. The FileExistsUTF8 routine is called to determine if the file exists on the local file system. SetFlag is called to update the fsciExists flag for the cache item with the given name.
