◆ BeginMultiTag()

virtual bool iser::CCompactXmlReadArchiveBase::BeginMultiTag	(	const iser::CArchiveTag &	tag,
		const iser::CArchiveTag &	subTag,
		int &	count
	)

overridevirtual

Begins a tagged section containing multiple elements of the same type.

BeginMultiTag is used for serializing collections, arrays, or lists where you have multiple items of the same structure. The count parameter works differently for reading vs. writing:

Writing: Pass the number of elements you will serialize
Reading: The archive sets count to the number of elements stored

Parameters

tag	Main container tag for the entire collection
subTag	Tag type for each individual element in the collection
count	[in/out] For writing: number of elements to serialize For reading: set by archive to number of stored elements

Returns: true if successful, false on error

// Writing a list
if (archive.IsStoring()) {
       int count = m_items.count();
       archive.BeginMultiTag(listTag, itemTag, count);
       for (const Item& item : m_items) {
              archive.BeginTag(itemTag);
              item.Serialize(archive);
              archive.EndTag(itemTag);
       }
       archive.EndTag(listTag);
}
// Reading a list
else {
       int count;
       archive.BeginMultiTag(listTag, itemTag, count);
       m_items.clear();
       for (int i = 0; i < count; ++i) {
              archive.BeginTag(itemTag);
              Item item;
              item.Serialize(archive);
              m_items.append(item);
              archive.EndTag(itemTag);
       }
       archive.EndTag(listTag);
}

Reimplemented from iser::CArchiveBase.

◆ BeginTag()

virtual bool iser::CCompactXmlReadArchiveBase::BeginTag ( const iser::CArchiveTag & tag )

overridevirtual

Begins a tagged section in the archive.

Tags organize data into logical units with names and descriptions. Every BeginTag() must be matched with an EndTag() call. Tags can be nested to create hierarchical data structures.

Parameters

tag	The tag object describing this section. Use static CArchiveTag instances to avoid repeated construction overhead.

Returns: true if the tag was successfully opened, false on error

Note: Always match BeginTag() with EndTag(); Check the return value and propagate errors; For collections, use BeginMultiTag() instead

static iser::CArchiveTag personTag("Person", "Person data");
if (archive.BeginTag(personTag)) {
       archive.Process(name);
       archive.Process(age);
       archive.EndTag(personTag);
}

Implements iser::IArchive.

◆ DecorateMessage()

virtual void iser::CCompactXmlReadArchiveBase::DecorateMessage	(	istd::IInformationProvider::InformationCategory	category,
		int	id,
		int	flags,
		QString &	message,
		QString &	messageSource
	)		const

overrideprotectedvirtual

Decorate message parts before outputting.

Reimplemented from istd::ILogger.

Reimplemented in ifile::CCompactXmlFileReadArchive, ifile::CCompressedXmlFileReadArchive, and iser::CCompactXmlMemReadArchive.

◆ EndTag()

virtual bool iser::CCompactXmlReadArchiveBase::EndTag ( const iser::CArchiveTag & tag )

overridevirtual

Ends a tagged section in the archive.

Must be called after BeginTag() or BeginMultiTag() to close the section. If tag skipping is supported and not all data was read, this will skip to the end of the tag section, enabling forward compatibility.

Parameters

tag	The same tag object passed to BeginTag() or BeginMultiTag()

Returns: true if successful, false on error

Note: Always call EndTag() even if errors occurred within the tag; The tag parameter must match the one used in BeginTag(); If IsTagSkippingSupported() returns false, you must read all data before calling EndTag()

static iser::CArchiveTag dataTag("Data", "My data");
if (archive.BeginTag(dataTag)) {
       bool success = archive.Process(myData);
       archive.EndTag(dataTag);  // Always call, even if Process failed
       if (!success) return false;
}

Implements iser::IArchive.

◆ IsTagSkippingSupported()

virtual bool iser::CCompactXmlReadArchiveBase::IsTagSkippingSupported ( ) const

overridevirtual

Checks if skipping to the end of a tag on EndTag() is supported.

Some archive types (like XML) support skipping unread content within a tag, allowing forward compatibility. When reading an archive created by a newer version that added fields, this feature lets you skip unknown data.

Returns: true if the archive supports tag skipping, false otherwise

Note: Binary archives typically don't support skipping, requiring all data to be read sequentially.; XML and JSON archives usually support skipping.

if (archive.IsTagSkippingSupported()) {
       // Can safely skip new fields added in future versions
} else {
       // Must read all data in exact order
}
