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_nameTable or descriptor name, as used in XML structures.
[in]standardsA bit mask of standards which define this structure.
[in]xml_legacy_nameTable 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]otherThe 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()

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

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]duckTSDuck execution context.
[in,out]parentThe parent node for the new XML tree.
Returns
The new XML element.

◆ fromXML()

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

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]duckTSDuck execution context.
[in]elementXML 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.

◆ operator=()

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

Assignment operator.

Parameters
[in]otherThe other instance to copy.
Returns
A reference to this object.

◆ clearContent()

virtual void ts::AbstractSignalization::clearContent ( )
protectedpure virtual

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.

◆ 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]duckTSDuck execution context.
[in]elementXML element to convert.
Returns
True if the analysis is correct, false otherwise.
