Class CqlColumnListImpl<C>

java.lang.Object

com.netflix.astyanax.cql.reads.model.CqlColumnListImpl<C>

Type Parameters:

C -

All Implemented Interfaces:

com.netflix.astyanax.model.ColumnList<C>, java.lang.Iterable<com.netflix.astyanax.model.Column<C>>

public class CqlColumnListImpl<C>
extends java.lang.Object
implements com.netflix.astyanax.model.ColumnList<C>

Class that implements the ColumnList interface. Note that this class handles the case where the table schema could contain a clustering key or just regular columns for a flat table. In the case of a flat table, each row has a unique set of columns. In the case of a clustering key, each row is a unique column. There are 2 separate constructors to this class in order to handle each of these cases.

CqlColumnListImpl(java.util.List<com.datastax.driver.core.Row> rows, com.netflix.astyanax.model.ColumnFamily<?,?> cf) This constructor is meant to be used when we are using the CQL3 table but still in the legacy thrift mode
CqlColumnListImpl(com.datastax.driver.core.Row row, com.netflix.astyanax.model.ColumnFamily<?,?> cf) This constructor is meant to be called when we have a table with standard columns i.e no composites, just plain columns
