Examples of com.netflix.astyanax.model.ColumnFamily

com.netflix.astyanax.model.ColumnFamily
Basic column family definition. The column family definition encapsulates the column family name as well as the type and serializers for the row keys and first level columns. Super column subcolumn name type and serializers are specified using a ColumnPath. @author elandau @param < K> @param < C>
