Get the 'stat' information for the specified path, using the cache to accelerate it if possible.

FileSystemStatCache::get - Get the 'stat' information for the specified path, using the cache to accelerate it if possible.

Returns: true if the path does not exist or false if it exists.

If isFile is true, then this lookup should only return success for files (not directories). If it is false this lookup should only return success for directories (not files). On a successful file lookup, the implementation can optionally fill in F with a valid File object and the client guarantees that it will close it.

This returns true if the path does not exist or false if it exists.

If isFile is true, then this lookup should only return success for files (not directories). If it is false this lookup should only return success for directories (not files). On a successful file lookup, the implementation can optionally fill in FileDescriptor with a valid descriptor and the client guarantees that it will close it.
