Member Function Documentation

virtual void casacore::TableExprGroupAggr::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.

template<typename T >

MArray<T> casacore::TableExprGroupAggr::getArray

(

const vector< TableExprId > &

ids

)

[inline, protected]

Return scalar values as a Vector.

Array values are returned as an array with one more axis. Use the first non-null value to determine the shape and if masked.

All arrays are null.
