Detailed Description

Abstract base class for MPEG PSI/SI tables and descriptors.

Some methods are declared as "virtual final". Since these methods are not inherited, this seems useless. This is in fact a compilation check. These methods were formerly designed to be overridden by subclasses but the implementation has changed. They are now defined in this class only and call a new pure virtual method. The "final" attribute is here to detect old subclasses which do not yet use the new scheme.

Constructor & Destructor Documentation

AbstractSignalization() [1/2]

ts::AbstractSignalization::AbstractSignalization ( const UChar *  xml_name, Standards  standards, const UChar *  xml_legacy_name = nullptr  )

protected

Protected constructor for subclasses.

Parameters

[in]	xml_name	Table or descriptor name, as used in XML structures.
[in]	standards	A bit mask of standards which define this structure.
[in]	xml_legacy_name	Table or descriptor legacy XML name. Ignored if null pointer.

AbstractSignalization() [2/2]

ts::AbstractSignalization::AbstractSignalization ( const AbstractSignalization &  other )

protecteddefault

Copy constructor.

Use default implementation, just tell the compiler we understand the consequences of copying a pointer member.

Parameters

[in]

other

The other instance to copy.

Member Function Documentation

isValid()

bool ts::AbstractSignalization::isValid ( ) const

inline

Check if this object is valid.

Returns

True if this object is valid.

invalidate()

void ts::AbstractSignalization::invalidate ( )

inline

Invalidate this object.

This object must be rebuilt.

clear()

virtual void ts::AbstractSignalization::clear ( )

virtual

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::AbstractLongTable.

xmlName()

UString ts::AbstractSignalization::xmlName

(

)

const

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

finalvirtual

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.

Parameters

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

Returns

The new XML element.

fromXML()

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

finalvirtual

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.

Parameters

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

definingStandards()

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

overridevirtual

Get the list of standards which define this object.

Returns

A bit mask of standards.

Implements ts::AbstractDefinedByStandards.

SerializeFixedLength()

static bool ts::AbstractSignalization::SerializeFixedLength ( DuckContext &  duck, ByteBlock &  bb, const UString &  str, const size_t  size  )

static

This static method serializes a DVB string with a required fixed size.

Parameters

[in,out]	duck	TSDuck execution context.
[in,out]	bb	A byte-block where str will be appended if its size is correct.
[in]	str	String to serialize.
[in]	size	Required size in bytes of the serialized string.

Returns

True if the size has the required length and has been serialized.

SerializeLanguageCode()

static bool ts::AbstractSignalization::SerializeLanguageCode ( ByteBlock &  bb, const UString &  str, bool  allow_empty = false  )

static

This static method serializes a 3-byte language or country code.

Parameters

[in]	allow_empty	If true, an empty string is allowed and serialized as zeroes.

Returns

True if the size has the required length and has been serialized.

DeserializeLanguageCode()

static UString ts::AbstractSignalization::DeserializeLanguageCode ( const uint8_t *  data )

static

This static method deserializes a 3-byte language or country code.

Parameters

[in]

data

Address of a 3-byte memory area.

Returns

Deserialized string.

operator=()

AbstractSignalization& ts::AbstractSignalization::operator= ( const AbstractSignalization &  other )

analyzeXML()

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

protectedpure virtual

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.

Deserialize a 3-byte language or country code.

Parameters

[out]	lang	Deserialized language code.
[in,out]	data	Address of memory area. Adjusted to point after the deserialized data.
[in,out]	size	Remaining size in bytes of memory area. Adjusted remove the deserialized data.

Returns

True on success, false on error. On error, the object is invalidated.

deserializeInt()

template<typename INT , typename std::enable_if< std::is_integral< INT >::value >::type * = nullptr>

bool ts::AbstractSignalization::deserializeInt ( INT &  value, const uint8_t *&  data, size_t &  size  )

protected

Deserialize an integer.

Template Parameters

INT	Some integer type.

Parameters

[out]	value	Deserialized integer value.
[in,out]	data	Address of memory area. Adjusted to point after the deserialized data.
[in,out]	size	Remaining size in bytes of memory area. Adjusted remove the deserialized data.

Returns

True on success, false on error. On error, the object is invalidated.

deserializeBool()

bool ts::AbstractSignalization::deserializeBool ( bool &  value, const uint8_t *&  data, size_t &  size, size_t  bit = 0  )

protected

Deserialize a one-bit boolean inside one byte.

Parameters

[out]	value	Deserialized bool value.
[in,out]	data	Address of memory area. Adjusted to point after the deserialized data (one byte).
[in,out]	size	Remaining size in bytes of memory area. Adjusted remove the deserialized data.
[in]	bit	Bit number of the boolean in the deserialized byte, from 0 (LSB) to 7 (MSB).

Returns

True on success, false on error. On error, the object is invalidated.
