FunctionType  ,
std::vector< TENShPtr > &   
)
static

Check the data and value types of the operands.

It sets the exptected data and value types of the operands. Set the value type of the function result and returns the data type of the function result.

void casacore::TableExprFuncNode::fillChildNodes ( const vector< TENShPtr > &  nodes,
const Block< Int > &  dtypeOper 
)

Link the children to the node and convert the children to constants if possible.

void casacore::TableExprFuncNode::fillUnits ( )

Fill the result unit in the node.

Adapt the children nodes if their units need to be converted. It returns a possible scale factor in case result unit is SI (for sqrt).
