Public Member Functions
	SimpleMultiFileList (vector< OpenFileInfo > paths)
	Construct a SimpleMultiFileList from a list of already expanded files.

vector< OpenFileInfo >	GetAllFiles () const override
	Main MultiFileList API.

FileExpandResult	GetExpandResult () const override

idx_t	GetTotalFileCount () const override
	Get the total file count - forces all files to be expanded / known so the exact count can be computed.

Public Member Functions inherited from duckdb::MultiFileList
MultiFileListIterationHelper	Files () const
	Get Iterator over the files for pretty for loops.

void	InitializeScan (MultiFileListScanData &iterator) const
	Initialize a sequential scan over a file list.

bool	Scan (MultiFileListScanData &iterator, OpenFileInfo &result_file) const
	Scan the next file into result_file, returns false when out of files.

OpenFileInfo	GetFirstFile () const
	Returns the first file or an empty string if GetTotalFileCount() == 0.

bool	IsEmpty () const
	Syntactic sugar for GetExpandResult() == FileExpandResult::NO_FILES.

virtual unique_ptr< MultiFileList >	ComplexFilterPushdown (ClientContext &context, const MultiFileOptions &options, MultiFilePushdownInfo &info, vector< unique_ptr< Expression > > &filters) const
	Virtual functions for subclasses.

virtual unique_ptr< MultiFileList >	DynamicFilterPushdown (ClientContext &context, const MultiFileOptions &options, const vector< string > &names, const vector< LogicalType > &types, const vector< column_t > &column_ids, TableFilterSet &filters) const

virtual MultiFileCount	GetFileCount (idx_t min_exact_count=0) const

virtual vector< OpenFileInfo >	GetDisplayFileList (optional_idx max_files=optional_idx()) const

virtual unique_ptr< NodeStatistics >	GetCardinality (ClientContext &context) const

virtual unique_ptr< MultiFileList >	Copy () const

template<class TARGET >

Protected Member Functions
OpenFileInfo	GetFile (idx_t i) const override
	Main MultiFileList API.

Protected Member Functions inherited from duckdb::MultiFileList
virtual bool	FileIsAvailable (idx_t i) const
	Whether or not the file at the index is available instantly - or if this requires additional I/O.

Protected Attributes
const vector< OpenFileInfo >	paths
	The list of input paths.

Detailed Description

MultiFileList that takes a list of files and produces the same list of paths. Useful for quickly wrapping existing vectors of paths in a MultiFileList without changing any code
