Detailed Description

The FileDataBlock class is a reference to a certain data block of a file stream.

Definition at line 90 of file abstractattachment.h.

Constructor & Destructor Documentation

TagParser::FileDataBlock::FileDataBlock	(	std::string_view	path,
		Diagnostics &	diag,
		AbortableProgressFeedback &	progress
	)

Constructs a new FileDataBlock with the specified path.

Opens a file stream with the specified path.

Exceptions

Throws ios_base::failure when an IO error occurs.

Definition at line 107 of file abstractattachment.cpp.

TagParser::FileDataBlock::~FileDataBlock ( )

Destroys the FileDataBlock.

Remarks: This method is needed although it is empty. Otherwise the default d'tor would be inlined where FileDataBlock is used creating a dependency to MediaFileInfo which therefore couldn't be opaque anymore.

Definition at line 124 of file abstractattachment.cpp.

const MediaFileInfo * TagParser::FileDataBlock::fileInfo ( ) const
