Synopsis

Example

Motivation

Several GBT backends have a SAMPLER table associated with each scan. These tables are often very much the same from scan to scan and there are a limited number of different samplers which a user will typically choose. Hence it makes sense to have these be simply indexed by row number and to re-use rows in the filled MS table when possible.

To Do

the GBTMSType*Filler classes need to share a base class.

Constructor & Destructor Documentation

GBTMSTypeSampFiller::GBTMSTypeSampFiller ( const String & tableName )

open an already existing table - type is extracted from the tableName using everything before the last "_SAMPLER" to the previous "_"

GBTMSTypeSampFiller::GBTMSTypeSampFiller	(	Table &	attachTable,
		const String &	type
	)

create a new, empty table attached to the given table using the indicate typeSamp.

Member Function Documentation

void GBTMSTypeSampFiller::checkRecord ( const Record & row ) [private]

this checks the record and adds columns as required

void GBTMSTypeSampFiller::fill ( const Table & other )

Fill the indicated table to this table.

Each column in other maps to a column in the this table. The type of the columns must match that in the existing table. Columns not already in this table will result in new columns. If there are only scalar columns, then new rows will only be added if this row does not already exist in the table. If there are any non-scalar columns, a new row is always added.

void GBTMSTypeSampFiller::fillRow ( const Record & row ) [private]

we fill on a row by row basis

void GBTMSTypeSampFiller::flush ( ) [inline]

flush this table

void GBTMSTypeSampFiller::handleColumn ( const String & colname )

mark the column of the given name as handled - there is no check to see if that column exists

uInt GBTMSTypeSampFiller::nrow ( ) [inline]

how many rows in this table
