How to use

getAliasMap

method

in

org.apache.kylin.storage.StorageContext

private List<String> getColumnNames(List<TblColRef> dimensionColumns) {
  Map<TblColRef, String> aliasMap = context.getAliasMap();
  List<String> result = new ArrayList<String>(dimensionColumns.size());
  for (TblColRef col : dimensionColumns)
    result.add(findName(col, aliasMap));
  return result;
}

rowKeyDecoder.decode(rowkey);
List<TblColRef> columns = rowKeyDecoder.getColumns();
List<String> dimensionNames = rowKeyDecoder.getNames(context.getAliasMap());
List<String> dimensionValues = rowKeyDecoder.getValues();
for (int i = 0; i < dimensionNames.size(); i++) {

rowKeyDecoder.setCuboid(cuboid);
List<TblColRef> rowColumns = rowKeyDecoder.getColumns();
List<String> colNames = rowKeyDecoder.getNames(context.getAliasMap());
for (int i = 0; i < rowColumns.size(); i++) {
  TblColRef column = rowColumns.get(i);
      String derivedField = getFieldName(derivedCol, context.getAliasMap());
      info.setField(derivedField, derivedCol, derivedCol.getType().getName(), index++);
