Constructor & Destructor Documentation

◆ FileStorage() [1/2]

cv::FileStorage::FileStorage ( )

Python:
	<FileStorage object>	=	cv.FileStorage(		)
	<FileStorage object>	=	cv.FileStorage(	filename, flags[, encoding]	)

The constructors.

The full constructor opens the file. Alternatively you can use the default constructor and then call FileStorage::open.

◆ FileStorage() [2/2]

cv::FileStorage::FileStorage	(	const String &	filename,
		int	flags,
		const String &	encoding = `String()`
	)

Python:
	<FileStorage object>	=	cv.FileStorage(		)
	<FileStorage object>	=	cv.FileStorage(	filename, flags[, encoding]	)

Opens a file.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. See description of parameters in FileStorage::FileStorage. The method calls FileStorage::release before opening the file.

Parameters

filename	Name of the file to open or the text string to read the data from. Extension of the file (.xml, .yml/.yaml or .json) determines its format (XML, YAML or JSON respectively). Also you can append .gz to work with compressed files, for example myHugeMatrix.xml.gz. If both FileStorage::WRITE and FileStorage::MEMORY flags are specified, source is used just to specify the output file format (e.g. mydata.xml, .yml etc.). A file name can also contain parameters. You can use this format, "*?base64" (e.g. "file.json?base64" (case sensitive)), as an alternative to FileStorage::BASE64 flag.
flags	Mode of operation. One of FileStorage::Mode
encoding	Encoding of the file. Note that UTF-16 XML encoding is not supported currently and you should use 8-bit encoding instead of it.

◆ ~FileStorage()

virtual cv::FileStorage::~FileStorage ( )

virtual

the destructor. calls release()

Member Function Documentation

◆ endWriteStruct()

void cv::FileStorage::endWriteStruct ( )

Python:
	None	=	cv.FileStorage.endWriteStruct(		)

Finishes writing nested structure (should pair startWriteStruct())

◆ getDefaultObjectName()

static String cv::FileStorage::getDefaultObjectName ( const String & filename )

static

Returns the normalized object name for the specified name of a file.

Parameters

filename Name of a file

Returns: The normalized object name.

◆ getFirstTopLevelNode()

FileNode cv::FileStorage::getFirstTopLevelNode ( ) const

Python:
	retval	=	cv.FileStorage.getFirstTopLevelNode(		)

Returns: The first element of the top-level mapping.

◆ getFormat()

int cv::FileStorage::getFormat ( ) const

Python:
	retval	=	cv.FileStorage.getFormat(		)

Returns: The current format, see FileStorage::Mode

◆ isOpened()

virtual bool cv::FileStorage::isOpened ( ) const

virtual

Python:
	retval	=	cv.FileStorage.isOpened(		)

Checks whether the file is opened.

Returns: true if the object is associated with the current file and false otherwise. It is a good practice to call this method after you tried to open a file.

Examples:: samples/cpp/filestorage.cpp.

◆ open()

virtual bool cv::FileStorage::open	(	const String &	filename,
		int	flags,
		const String &	encoding = `String()`
	)

virtual

Python:
	retval	=	cv.FileStorage.open(	filename, flags[, encoding]	)

Opens a file.

See description of parameters in FileStorage::FileStorage. The method calls FileStorage::release before opening the file.

Parameters

filename	Name of the file to open or the text string to read the data from. Extension of the file (.xml, .yml/.yaml or .json) determines its format (XML, YAML or JSON respectively). Also you can append .gz to work with compressed files, for example myHugeMatrix.xml.gz. If both FileStorage::WRITE and FileStorage::MEMORY flags are specified, source is used just to specify the output file format (e.g. mydata.xml, .yml etc.). A file name can also contain parameters. You can use this format, "*?base64" (e.g. "file.json?base64" (case sensitive)), as an alternative to FileStorage::BASE64 flag.
flags	Mode of operation. One of FileStorage::Mode
encoding	Encoding of the file. Note that UTF-16 XML encoding is not supported currently and you should use 8-bit encoding instead of it.

◆ operator[]() [1/2]

FileNode cv::FileStorage::operator[] ( const String & nodename ) const

Python:
	retval	=	cv.FileStorage.getNode(	nodename	)

Returns the specified element of the top-level mapping.

Parameters

nodename Name of the file node.

Returns: Node with the given name.

◆ operator[]() [2/2]

FileNode cv::FileStorage::operator[] ( const char * nodename ) const

Python:
	retval	=	cv.FileStorage.getNode(	nodename	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ release()

virtual void cv::FileStorage::release ( )

virtual

Python:
	None	=	cv.FileStorage.release(		)

Closes the file and releases all the memory buffers.

Call this method after all I/O operations with the storage are finished.

◆ releaseAndGetString()

virtual String cv::FileStorage::releaseAndGetString ( )

virtual

Python:
	retval	=	cv.FileStorage.releaseAndGetString(		)

Closes the file and releases all the memory buffers.

Call this method after all I/O operations with the storage are finished. If the storage was opened for writing data and FileStorage::WRITE was specified

Examples:: samples/cpp/filestorage.cpp.

◆ root()

FileNode cv::FileStorage::root ( int streamidx = 0 ) const

Python:
	retval	=	cv.FileStorage.root(	[, streamidx]	)

Returns the top-level mapping.

Parameters

streamidx Zero-based index of the stream. In most cases there is only one stream in the file. However, YAML supports multiple streams and so there can be several.

Returns: The top-level mapping.

◆ startWriteStruct()

void cv::FileStorage::startWriteStruct	(	const String &	name,
		int	flags,
		const String &	typeName = `String()`
	)

Python:
	None	=	cv.FileStorage.startWriteStruct(	name, flags[, typeName]	)

Starts to write a nested structure (sequence or a mapping).

Parameters

name	name of the structure (if it's a member of parent mapping, otherwise it should be empty
flags	type of the structure (FileNode::MAP or FileNode::SEQ (both with optional FileNode::FLOW)).
typeName	usually an empty string

◆ write() [1/5]

void cv::FileStorage::write	(	const String &	name,
		int	val
	)

Python:
	None	=	cv.FileStorage.write(	name, val	)

Simplified writing API to use with bindings.

Parameters

name	Name of the written object
val	Value of the written object

◆ write() [2/5]

		double	val
	)

		const std::vector< String > &	val
	)

Python:

◆ writeComment()

void cv::FileStorage::writeComment	(	const String &	comment,
		bool	append = `false`

Python:
	None	=	cv.FileStorage.writeComment(	comment[, append]	)

Writes a comment.

The function writes a comment into file storage. The comments are skipped when the storage is read.

Parameters

comment	The written comment, single-line or multi-line
append	If true, the function tries to put the comment at the end of current line. Else if the comment is multi-line, or if it does not fit at the end of the current line, the comment starts a new line.

		const void *	vec,
		size_t	len
	)

Writes multiple numbers.

Writes one or more numbers of the specified format to the currently written structure. Usually it is more convenient to use operator << instead of this method.

Parameters

fmt	Specification of each array element, see format specification
vec	Pointer to the written array.
len	Number of the uchar elements to write.
