Method Details

fillOutputData

protected List<Map<String,Object>> fillOutputData(List resList,
 List<AbstractDbDataLoader.OutputValue> parametersNames)

fillOutputRow

protected Map<String,Object> fillOutputRow(Object resultRecordObject,
 List<AbstractDbDataLoader.OutputValue> parametersNames)

Maps a single result record (an Object[] of column values, or a scalar) into an output row map. Used both by the batch fillOutputData(java.util.List, java.util.List<io.jmix.reports.yarg.loaders.impl.AbstractDbDataLoader.OutputValue>) and by the streaming cursors, which shape one row at a time and must not allocate a throwaway list per row.

prepareQuery

protected AbstractDbDataLoader.QueryPack prepareQuery(String query,
 BandData parentBand,
 Map<String,Object> reportParams)

processQueryTemplate

protected String processQueryTemplate(String query,
 @Nullable BandData parentBand,
 Map<String,Object> reportParams)

findParameterNames

protected HashSet<String> findParameterNames(String query)

insertParameterToQuery

protected String insertParameterToQuery(String query,
 AbstractDbDataLoader.QueryParameter parameter)
