Constructor & Destructor Documentation

◆ AbstractSignalization() [1/2]

ts::AbstractSignalization::AbstractSignalization ( const UChar xml_name,
Standards  standards 
)
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.

◆ 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.

◆ 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
virtual

This method converts this object to XML.

When this object is valid, the default implementation of toXML() creates a root node with the default XML name and then invoke buildXML() to populate the XML node.

Subclasses have the choice to either implement buildXML() or toXML(). If the object is serialized as one single XML node, it is simpler to implement buildXML().

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

Reimplemented in ts::SSULinkageDescriptor, and ts::SSUDataBroadcastIdDescriptor.

◆ fromXML()

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

This abstract converts an XML structure to a table or descriptor.

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

Parameters
[in,out]duckTSDuck execution context.
[in]elementXML element to convert.

const size_t  size 
)
static

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

bool  allow_empty = false 
)
static

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

Parameters
[in,out]bbA byte-block where str will be appended if its size is correct.

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]dataAddress of a 3-byte memory area.
Returns
Deserialized string.

◆ operator=()

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

◆ buildXML()

virtual void ts::AbstractSignalization::buildXML ( DuckContext duck,
xml::Element root 
) const
protectedvirtual

Helper method to convert this object to XML.

When this object is valid, the default implementation of toXML() creates a root node with the default XML name and then invoke buildXML() to populate the XML node.

The default implementation is to do nothing. Subclasses which override toXML() do not need to implement buildXML() since it won't be invoked.

Parameters
[in,out]rootThe root node for the new XML tree.
[in,out]duckTSDuck execution context.
