Synopsis
Aggregate class determining the fractile of values in a group.
It is a lazy aggregate class, thus apply does nothing. Instead, getDouble assembles the values and determines the fractile.

Member Function Documentation
◆ apply()
|
virtual |
Get the operand's value for the given row and apply it to the aggregation.
This function should not be called for lazy classes.
Implements casacore::TableExprGroupFuncBase.
◆ getDouble()
|
virtual |
Reimplemented from casacore::TableExprGroupFuncDouble.
◆ isLazy()
|
virtual |
Does the aggregate function use lazy semantics? The default implementation returns False.
Reimplemented from casacore::TableExprGroupFuncBase.
