Detailed Description

Representation of a binary MPEG PSI/SI table.

A table is built by adding sections using addSection(). When all sections are present, the table becomes valid.

Data from sections are not deeply copied thanks to the implicit sharing mechanism of the Qt containers. Whenever a section is modified, then a copy-on-write occurs.

The table_id, version and number of sections is determined when the first section is added. Subsequent sections must have the same properties.

Member Typedef Documentation

◆ SectionVector

typedef QVector<QtsSectionPtr> QtsTable::SectionVector

private

< Vector of smart pointers to sections.

Constructor & Destructor Documentation

◆ QtsTable() [1/2]

QtsTable::QtsTable ( )

Default constructor.

◆ QtsTable() [2/2]

QtsTable::QtsTable ( const QtsTable & other )

Copy constructor.

Data from sections are not deeply copied thanks to the implicit sharing mechanism of the Qt containers. Whenever a section is modified, then a copy-on-write occurs.

Parameters

[in] other Other instance to copy.

Member Function Documentation

◆ operator=()

const QtsTable & QtsTable::operator= ( const QtsTable & other )

Assignment operator.

Data from sections are not deeply copied thanks to the implicit sharing mechanism of the Qt containers. Whenever a section is modified, then a copy-on-write occurs.

Parameters

[in] other Other instance to copy.

◆ operator==()

bool QtsTable::operator== ( const QtsTable & other ) const

Comparison operator.

Parameters

[in] other Other instance to compare.

Returns: True if the tables are identical, false otherwise. The source PID's are ignored, only the sections contents are compared. Note: Invalid tables are never identical.

◆ operator!=()

bool QtsTable::operator!= ( const QtsTable & other ) const

inline

Difference operator.

Parameters

[in] other Other instance to compare.

Returns: True if the tables are different, false otherwise. The source PID's are ignored, only the sections contents are compared. Note: Invalid tables are never identical.

◆ addSection() [1/2]

bool QtsTable::addSection	(	const QtsSection &	section,
		bool	replace = `true`,
		bool	grow = `true`
	)

inline

Add a section to a table.

Parameters

[in]	section	The section to add.
[in]	replace	If true, an existing section may be replaced. Otherwise, replacing an existing section is an error.
[in]	grow	If true, the "last_section_number" of the section may be greater than the "last_section_number" in the table. In this case, all sections which were previously added in the table are modified.

Returns: True on success, false if the section could not be added (inconsistent property).

◆ addSection() [2/2]

bool QtsTable::addSection	(	const QtsSectionPtr &	section,
		bool	replace = `true`,
		bool	grow = `true`
	)

Add a section to a table.

Parameters

[in]	section	A smart pointer to the section to add. The section is not copied, only the smart pointer is used. Do not modify the section object from outside after invoking this method.
[in]	replace	If true, an existing section may be replaced. Otherwise, replacing an existing section is an error.
[in]	grow	If true, the "last_section_number" of the section may be greater than the "last_section_number" in the table. In this case, all sections which were previously added in the table are modified.

Returns: True on success, false if the section could not be added (inconsistent property).

◆ isValid()

bool QtsTable::isValid ( ) const

inline

Check if the table is valid.

Returns: True if the table is valid, false otherwise;

◆ clear()

void QtsTable::clear ( )

Clear the content of the table.

The table must be rebuilt using calls to addSection().

◆ tableId()

QtsTableId QtsTable::tableId ( ) const

inline

Get the table id.

Returns: The table id.

◆ tableIdExtension()

quint16 QtsTable::tableIdExtension ( ) const

inline

Get the table id extension (long sections only).

Returns: The table id extension (zero for short sections).

◆ version()

quint8 QtsTable::version ( ) const

inline

Get the table version (long sections only).

Returns: The table version (zero for short sections).

◆ sourcePid()

QtsPid QtsTable::sourcePid ( ) const

inline

Get the PID from which the section was collected.

Returns: The PID from which the section was collected.

◆ setTableIdExtension()

void QtsTable::setTableIdExtension	(	quint16	tidExt,
		bool	recomputeCrc = `true`
	)

Modify the table id extension.

Parameters

[in]	tidExt	New table id extension.
[in]	recomputeCrc	If true, recompute the CRC32 of the section.

◆ setVersion()

void QtsTable::setVersion	(	quint8	version,
		bool	recomputeCrc = `true`
	)

Modify the table version.

Parameters

[in]	version	New table version.
[in]	recomputeCrc	If true, recompute the CRC32 of the section.

◆ setSourcePid()

void QtsTable::setSourcePid ( QtsPid pid )

Set the PID from which the table was collected (informational only).

Parameters

[in] pid The PID from which the table was collected.

◆ getFirstTsPacketIndex()

QtsPacketCounter QtsTable::getFirstTsPacketIndex ( ) const

Get the index of first TS packet of the table in the demultiplexed stream.

Returns: The index of first TS packet of the table.

◆ getLastTsPacketIndex()

QtsPacketCounter QtsTable::getLastTsPacketIndex ( ) const

Get the index of last TS packet of the table in the demultiplexed stream.

Returns: The index of last TS packet of the table.

◆ sectionCount()

int QtsTable::sectionCount ( ) const

inline

Get the number of sections in the table.

Returns: The number of sections in the table.

◆ totalSize()

int QtsTable::totalSize ( ) const

Get the total size in bytes of all sections in the table.

Returns: The total size in bytes of all sections in the table.

◆ sectionAt()

QtsSectionPtr QtsTable::sectionAt ( int index ) const

Get a smart pointer to a section in the table.

Parameters

[in] index Section number.

Returns: A pointer to the section in the table or zero if not present. The pointed object shall not be modified.
