Detailed Description

BIOP message whose body is a list of Bindings.

Used for both BIOP::Directory and BIOP::ServiceGateway — the wire format and XML schema are identical; the only difference is the object_kind tag, which is preserved on the base BIOPMessage::object_kind field. Callers that need to distinguish them check kindTag() against BIOPObjectKind::DIRECTORY or BIOPObjectKind::SERVICE_GATEWAY.

Member Function Documentation

bindingList()

virtual const std::vector< BIOPBinding > * ts::BIOPBindingListMessage::bindingList ( ) const

inlineoverridevirtual

Bindings carried by this message, if any.

Returns

Pointer to the bindings vector for Directory / ServiceGateway messages, nullptr for kinds that don't carry bindings.

Reimplemented from ts::BIOPMessage.

deserializeBody()

virtual bool ts::BIOPBindingListMessage::deserializeBody ( PSIBuffer &  buf )

overrideprotectedvirtual

Deserialize the subclass-specific message body.

Parameters

[in,out]

buf

Deserialization buffer. Exactly the body bytes are available.

Returns

True on success.

Implements ts::BIOPMessage.

toXMLBody()

virtual void ts::BIOPBindingListMessage::toXMLBody ( DuckContext &  duck, xml::Element *  msg_element  ) const

overrideprotectedvirtual

Serialize the subclass-specific body to XML.

Parameters

[in,out]	duck	TSDuck execution context.
[in,out]	msg_element	The <BIOP_message> XML element to append body children to.

Implements ts::BIOPMessage.

fromXMLBody()

virtual bool ts::BIOPBindingListMessage::fromXMLBody ( DuckContext &  duck, const xml::Element *  msg_element  )

overrideprotectedvirtual

Deserialize the subclass-specific body from XML.

Parameters

[in,out]	duck	TSDuck execution context.
[in]	msg_element	The <BIOP_message> XML element containing the body.

Returns

True on success.

Implements ts::BIOPMessage.

kindTag()

std::string ts::BIOPMessage::kindTag ( ) const

inherited

Get the object kind as a trimmed string (without the trailing null, if any).

Returns

Trimmed kind string.

Parse()

static std::unique_ptr< BIOPMessage > ts::BIOPMessage::Parse ( PSIBuffer &  buf )

staticinherited

Parse one BIOP message from a buffer.

Dispatches to the concrete subclass based on object_kind.

Parameters

[in,out]

buf

Deserialization buffer.

Returns

Parsed message, or nullptr on error or unsupported kind.

toXML()

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

virtualinherited

This method converts a BIOPMessage to XML.

Parameters

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

fromXML()

virtual bool ts::BIOPMessage::fromXML ( DuckContext &  duck, const xml::Element *  element  )

virtualinherited

This method decodes an XML BIOPMessage.

Parameters

[in,out]	duck	TSDuck execution context.
[in]	element	The XML element containing the message.

Returns

True on success, false on error.

FromXML()

static std::unique_ptr< BIOPMessage > ts::BIOPMessage::FromXML ( DuckContext &  duck, const xml::Element *  element  )

staticinherited

Parse a BIOP message from an XML element.

Dispatches to the concrete subclass based on the object_kind attribute.

Parameters

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

Returns

Parsed message, or nullptr on error or unsupported kind.

CreateForKind()

static std::unique_ptr< BIOPMessage > ts::BIOPMessage::CreateForKind ( const std::string &  tag )

staticprotectedinherited

Construct a concrete BIOPMessage subclass for a given object_kind tag.

Parameters

[in]

tag

Trimmed object_kind string (e.g. "fil", "dir", "srg").

Returns

A new, empty subclass instance, or nullptr if the kind is unsupported.
