```
public class FieldMap
extends Object
```
Class for helping to deal with connecting field values with record descriptors for historical records and image browse data. Historical records have both structured data (persons with names, gender, facts; and relationships with facts) and 'fields'. A field often represents what was actually stated within some area of text on a historical document (or what was strongly implied by that document, such as the male gender of a father in a birth record). Each field has a list of field values, which can be of FieldValueType.Original, meaning what the document originally said (or structurally implied); or FieldValueType.Interpreted, meaning that a user or system interpreted. For example, a 'gender' field might have an original field value of "M", which, because it is in a Mexican census, means "Mujer", which means "Female". So the "Interpreted" field value might say "Mujer", or might say "Female"; or it is possible that both are included, since it is a list. These field values will be found within a Field of type "http://gedcomx.org/Gender", and that field will be found inside of the gender inside of the person it applies to. That gender will have a conclusional 'type' (e.g., "http://gedcomx.org/Female") that software will typically use. The 'structured data' of the record is typically used when dealing with what the record 'meant' or in displaying genealogical data to be used in copying over to a conclusion tree. The 'fields' of a record are typically used when display what the record originally 'said', in order to help communicate to a user some of the genealogical nuances that each record can have, including some that don't translate directly into the standardized conclusional structure that GedcomX supports. Having structured data with embedded fields (plus a list of fields at the person, relationship and record level) allows general-purpose genealogical use of 'what the record is telling us' (via the structure) as well as preservation of the special-purpose nuances of a particular record type (via the fields). A GedcomX document that represents a historical record will often have a SourceDescription that has a record 'descriptor' reference, which is the URL of a GedcomX document that represents the Collection that the record is found in, along with a "#" and local id of the record descriptor withing that collection's document, that describes the display labels to be used for displaying a field-value pair view of the record's field data. This class takes two GedcomX documents: a record and its collection (or, equivalently, the DocMap for both) and walks the structure of the record to find all of the field values, and builds the maps necessary to find all the field labelIds, the localized display labels for each labelId, and the values for each labelId found in the record. (Note that because a Field can have multiple FieldValues of the same type (original or interpreted), then each labelId can map to a list of values). Also, Census records are different from other records in that each person in a census household can have the same list of fields, so when displaying field values from census data, it must be done one person at a time. Therefore, each record will either support getValues(labelId) [i.e., for non-census] or getValues(person, labelId) [census], but not both. User: Randy Wilson Date: 7/31/2014 Time: 11:07 AM

    Parameters:
    
    recordDocMap - - DocMap of the GedcomX record to examine
    
    Returns:
    
    true if this is a census record, false otherwise.
