Synopsis

Aggregate class determining the fractile of array 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 void casacore::TableExprGroupFractileArrayDouble::apply ( const TableExprId &  id )

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 Double casacore::TableExprGroupFractileArrayDouble::getDouble ( const vector< TableExprId > &  ids )

virtual

Reimplemented from casacore::TableExprGroupFuncDouble.

isLazy()

virtual Bool casacore::TableExprGroupFractileArrayDouble::isLazy ( ) const

virtual

Does the aggregate function use lazy semantics? The default implementation returns False.

Reimplemented from casacore::TableExprGroupFuncBase.
