Examples of org.kiji.schema.KijiColumnName

org.kiji.schema.KijiColumnName
A Kiji column name is composed of one or two parts: a family and a qualifier. The qualifier can be either of map type or group type. If the column is of group type, the qualifier should ideally match VALID_LAYOUT_PATTERN. Empty qualifiers are normalized to null. That is, if fullName is of the form "family" or "family:", the qualifier will be treated as null. Qualifiers must be valid UTF-8.
