Member Typedef Documentation

◆ SpliceByComponent

using ts::SpliceInsert::SpliceByComponent = std::map<uint8_t, SpliceTime>

A map of 64-bit PTS time values, indexed by 8-bit component tags.

Used when the program is splice component by component, not as a whole.

Member Function Documentation

◆ adjustPTS()

void ts::SpliceInsert::adjustPTS ( uint64_t adjustment )

Adjust PTS time values using the "PTS adjustment" field from a splice information section.

Parameters

adjustment PTS adjustment value.

◆ highestPTS()

uint64_t ts::SpliceInsert::highestPTS ( ) const

Get the highest PTS value in the command.

Returns: The highest PTS value in the command or INVALID_PTS if none found.

◆ lowestPTS()

uint64_t ts::SpliceInsert::lowestPTS ( ) const

Get the lowest PTS value in the command.

Returns: The lowest PTS value in the command or INVALID_PTS if none found.

◆ programSplice()

bool ts::SpliceInsert::programSplice ( ) const

inline

Rebuild the value of the documented "program_splice_flag" field.

Returns: The "program_splice_flag" value.

◆ display()

void ts::SpliceInsert::display	(	TablesDisplay &	display,
		const UString &	margin
	)		const

Display the splice insert command.

Parameters

[in,out]	display	Display engine.
[in]	margin	Left margin content.

◆ deserialize()

int ts::SpliceInsert::deserialize	(	const uint8_t *	data,
		size_t	size
	)

Deserialize a SpliceInsert command from binary data.

Parameters

[in]	data	Address of data to deserialize.
[in]	size	Size of data buffer, possibly larger than the SpliceInsert command.

Returns: Deserialized size, -1 on incorrect data.

◆ serialize()

void ts::SpliceInsert::serialize ( ByteBlock & data ) const

Serialize the SpliceInsert command.

Parameters

[in,out] data The SpliceInsert command is serialized at the end of this byte block.

◆ clearContent()

virtual void ts::SpliceInsert::clearContent ( )

overrideprotectedvirtual

Helper method to clear the content of the table or descriptor.

It is called by clear(). In clearContent(), the subclass shall simply revert the value of all fields to their original values in the default constructor.

Implements ts::AbstractSignalization.

◆ buildXML()

virtual void ts::SpliceInsert::buildXML	(	DuckContext &	duck,
		xml::Element *	root
	)		const

overrideprotectedvirtual

Helper method to convert this object to XML.

It is called by toXML() only when the object is valid. The root element is already built with the appropriate XML node name. In buildXML(), the subclass shall simply populate the XML node.

Parameters

[in,out]	root	The root node for the new XML tree.
[in,out]	duck	TSDuck execution context.

Implements ts::AbstractSignalization.

◆ analyzeXML()

virtual bool ts::SpliceInsert::analyzeXML	(	DuckContext &	duck,
		const xml::Element *	element
	)

overrideprotectedvirtual

Helper method to convert this object from XML.

It is called by fromXML() after checking the validity of the XML node name. In analyzeXML(), the subclass shall populate the C++ object from the content of the XML node. If analyzeXML() returns false, this table or descriptor object is then invalidated and cleared.

Parameters

[in,out]	duck	TSDuck execution context.
[in]	element	XML element to convert.

Returns: True if the analysis is correct, false otherwise.

Implements ts::AbstractSignalization.

◆ isValid()

bool ts::AbstractSignalization::isValid ( ) const

inlineinherited

Check if this object is valid.

Returns: True if this object is valid.

◆ invalidate()

void ts::AbstractSignalization::invalidate ( )

inlineinherited

Invalidate this object.

This object must be rebuilt.

◆ clear()

virtual void ts::AbstractSignalization::clear ( )

virtualinherited

This method clears the content of the table or descriptor.

Upon return, the object is valid and in the same empty state as after a default constructor.

Reimplemented in ts::AbstractTable, and ts::AbstractLongTable.

◆ xmlName()

UString ts::AbstractSignalization::xmlName ( ) const

inherited

Get the XMl node name representing this table or descriptor.

Returns: The XML node name.

◆ toXML()

virtual xml::Element * ts::AbstractSignalization::toXML	(	DuckContext &	duck,
		xml::Element *	parent
	)		const

virtualinherited

This method converts this object to XML.

When this object is valid, this method creates a root node with the default XML name and then invokes buildXML() in the subclass to populate the XML node.

Important: Implementers of signalization classes shall not override this class. Implement the protected method buildXML() instead.

Parameters

[in,out]	duck	TSDuck execution context.
[in,out]	parent	The parent node for the new XML tree.

Returns: The new XML element.

Reimplemented in ts::AbstractTable.

◆ fromXML()

virtual void ts::AbstractSignalization::fromXML	(	DuckContext &	duck,
		const xml::Element *	element
	)

virtualinherited

This method converts an XML structure to a table or descriptor in this object.

In case of success, this object is replaced with the interpreted content of the XML structure. In case of error, this object is invalidated.

This method checks the name of the XML node and then invokes analyzeXML() in the subclass. Depending on the returned values of analyzeXML(), this object is either validated or invalidated.

Important: Implementers of signalization classes shall not override this class. Implement the protected method analyzeXML() instead.

Parameters

[in,out]	duck	TSDuck execution context.
[in]	element	XML element to convert.

Reimplemented in ts::AbstractTable.

◆ definingStandards()

virtual Standards ts::AbstractSignalization::definingStandards ( ) const

overridevirtualinherited

Get the list of standards which define this object.

Returns: A bit mask of standards.

Implements ts::AbstractDefinedByStandards.

◆ DataName()

template<typename INT , typename std::enable_if< std::is_integral< INT >::value, int >::type = 0>

static UString ts::AbstractSignalization::DataName	(	const UChar *	xml_name,
		const UChar *	section,

UString ts::AbstractSignalization::dataName	(	const UChar *	section,
		INT	value,
		NamesFlags	flags = `NamesFlags::NAME`,
		size_t	bits = `0`,
		INT	alternate = `0`
	)

inlineinherited

Get a name from a specified section in the DVB names file for that signalization structure.

Template Parameters

INT	An integer type.

Parameters

[in]	section	Name of section to search. Not case-sensitive. The actual section in the names file is prefixed by the XML name of the structure, followed by a dot.
[in]	value	Value to get the name for.
[in]	flags	Presentation flags.
