Detailed Description
A statistic definition must specify a field name and statistic type. Optionally, you can provide a name for the output statistic result.
Relevant samples:
- Statistical query: Query a table to get aggregated statistics back for a specific field.
- Statistical query (group & sort): Query a feature table for statistics, grouping and sorting by different fields.
Member Function Documentation
StatisticDefinition::StatisticDefinition ()
Default Constructor. Create an empty StatisticDefinition instance.
StatisticDefinition::StatisticDefinition (const QString &onFieldName , Esri::ArcGISRuntime::StatisticType statisticType , const QString &outputAlias )
Creates a statistic definition, with a field name (onFieldName), a statistic type (statisticType), and a name for the output statistic result (outputAlias).
StatisticDefinition::StatisticDefinition (const Esri::ArcGISRuntime::StatisticDefinition &other)
Copy constructor from other StatisticDefinition.
StatisticDefinition::StatisticDefinition (Esri::ArcGISRuntime::StatisticDefinition &&other)
Move constructor from other StatisticDefinition.
StatisticDefinition::~StatisticDefinition ()
Destructor
void StatisticDefinition::clear()
Clears this StatisticDefinition and sets back to empty.
bool StatisticDefinition::isEmpty () const
Returns whether this StatisticDefinition is empty.
QString StatisticDefinition::onFieldName () const
Returns the name of the field in the table containing values to be used for the statistic.
See also setOnFieldName().
QString StatisticDefinition::outputAlias () const
Returns the optional name for this statistic in the results.
