Detailed Description

The MatroskaTagField class is used by MatroskaTag to store the fields.

Constructor & Destructor Documentation

◆ MatroskaTagField() [1/2]

TagParser::MatroskaTagField::MatroskaTagField ( )

Constructs a new MatroskaTagField.

Definition at line 25 of file matroskatagfield.cpp.

◆ MatroskaTagField() [2/2]

TagParser::MatroskaTagField::MatroskaTagField	(	const std::string &	id,
		const TagValue &	value )

Constructs a new MatroskaTagField with the specified id and value.

Definition at line 32 of file matroskatagfield.cpp.

Member Function Documentation

◆ fieldIdFromString()

std::string TagParser::MatroskaTagField::fieldIdFromString ( std::string_view idString )

inlinestatic

Converts the specified ID string representation to an actual ID.

Remarks: As Matroska field IDs are text strings the string is just passed.

Definition at line 105 of file matroskatagfield.h.

◆ fieldIdToString()

std::string TagParser::MatroskaTagField::fieldIdToString ( const std::string & id )

inlinestatic

Returns the string representation for the specified id.

Remarks: As Matroska field IDs are text strings the string is just passed.

Definition at line 114 of file matroskatagfield.h.

◆ isAdditionalTypeInfoUsed()

bool TagParser::MatroskaTagField::isAdditionalTypeInfoUsed ( ) const

inline

Returns whether the additional type info is used.

Definition at line 88 of file matroskatagfield.h.

◆ make()

void TagParser::MatroskaTagField::make	(	std::ostream &	stream,
		Diagnostics &	diag )

Saves the field to the specified stream (makes a "SimpleTag" element).

Exceptions

Throws std::ios_base::failure when an IO error occurs.

Throws TagParser::Failure or a derived exception when a making error occurs.

Definition at line 184 of file matroskatagfield.cpp.

◆ normalizeId()

void TagParser::MatroskaTagField::normalizeId ( std::string & id )

static

Ensures the specified id is upper-case as recommended by the Matroska spec.

See also: https://matroska.org/technical/tagging.html#tag-formatting

Definition at line 193 of file matroskatagfield.cpp.

◆ prepareMaking()

MatroskaTagFieldMaker TagParser::MatroskaTagField::prepareMaking ( Diagnostics & diag )

Prepares making.

Returns: Returns a MatroskaTagFieldMaker object which can be used to actually make the field.

Remarks: The field must NOT be mutated after making is prepared when it is intended to actually make the field using the make method of the returned object.

Exceptions

Throws TagParser::Failure or a derived exception when a making error occurs.

This method might be useful when it is necessary to know the size of the field before making it.

Definition at line 162 of file matroskatagfield.cpp.

◆ reparse()

void TagParser::MatroskaTagField::reparse	(	EbmlElement &	simpleTagElement,
		Diagnostics &	diag,
		bool	parseNestedFields = true )

Parses field information from the specified EbmlElement.

The specified atom should be a simple tag element. These elements represents the fields of a MatroskaTag.

Exceptions

Throws	std::ios_base::failure when an IO error occurs.
Throws	TagParser::Failure or a derived exception when a parsing error occurs.

Definition at line 47 of file matroskatagfield.cpp.

◆ supportsNestedFields()

bool TagParser::MatroskaTagField::supportsNestedFields ( ) const

inline

Returns whether nested fields are supported.

Definition at line 96 of file matroskatagfield.h.
