Member Function Documentation

◆ BeginTag()

virtual bool iser::CBinaryWriteArchiveBase::BeginTag ( const 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);
}

See also: EndTag(), BeginMultiTag(), CArchiveTag

Implements iser::IArchive.

Reimplemented in ifile::CFileWriteArchive.

◆ EndTag()

virtual bool iser::CBinaryWriteArchiveBase::EndTag ( const 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;
}
