GedcomElement class

Base GEDCOM element Each line in a GEDCOM file is an element with the format level [pointer] tag [value] where level and tag are required, and pointer and value are optional.

Elements are arranged hierarchically according to their level, and elements with a level of zero are at the top level.

Elements with a level greater than zero are children of their parent. A pointer has the format @pname@, where pname is any sequence of characters and numbers. The pointer identifies the object being pointed to, so that any pointer included as the value of any element points back to the original object.

For example, an element may have a FAMS tag whose value is @F1@, meaning that this element points to the family record in which the associated person is a spouse.

Likewise, an element with a tag of FAMC has a value that points to a family record in which the associated person is a child.

See a GEDCOM file for examples of tags and their values.

Tags available to an element are available in tags.dart
