Detailed Description

A column in a concatenated table

Intended use:

Internal

Review Status

Reviewed By:: UNKNOWN

Prerequisite

Etymology

ConcatTable represents a column in a ConcatTable. A ConcatTable is a table referencing another table, usually as the result of a select, etc..

Synopsis

ConcatColumn handles the access of a column in a ConcatTable. It calls the corresponding function in the referenced column while converting the given row number to the row number in the referenced table.

Motivation

This class is untyped, i.e. not templated. Every call is sent to the underlying referenced BaseColumn which is typed by the virtual function mechanism. A ConcatColumn can never be used directly. A user always has to construct a typed ArrayColumn or ScalarColumn object to access a column. This means everyting is fully type safe.

To Do

Act upon removal of rows or the underlying column

Member Typedef Documentation

◆ AccessColumnFunc

typedef void casacore::ConcatColumn::AccessColumnFunc(BaseColumn *col, const Slicer *, ArrayBase &array)

private

Define the function to handle access to an entire column.

Definition at line 228 of file ConcatColumn.h.

◆ AccessRowsFunc

typedef void casacore::ConcatColumn::AccessRowsFunc(BaseColumn *col, const RefRows &rows, const Slicer *, ArrayBase &array)

private

Define the function to handle access to a number of rows.

Definition at line 232 of file ConcatColumn.h.

Constructor & Destructor Documentation

◆ ConcatColumn()

casacore::ConcatColumn::ConcatColumn	(	const BaseColumnDesc *	,
		ConcatTable *
	)

Construct the ConcatColumn.

It will point to the given column description, ConcatTable and referenced column. The ConcatTable will be used to convert the rownr to the rownr in the referenced column.

◆ ~ConcatColumn()

casacore::ConcatColumn::~ConcatColumn ( )

Member Function Documentation

◆ accessColumn()

void casacore::ConcatColumn::accessColumn	(	const Slicer *	ns,
		ArrayBase &	dataPtr,
		AccessColumnFunc *
	)		const

private

Access the data for an entire column.

◆ accessRows()

void casacore::ConcatColumn::accessRows	(	const RefRows &	rownrs,
		const Slicer *	ns,
		ArrayBase &	dataPtr,
		AccessRowsFunc *
	)		const

private

Access the data with multiple rows combined.

◆ allocIterBuf()

virtual void casacore::ConcatColumn::allocIterBuf	(	void *&	lastVal,
		void *&	curVal,
		CountedPtr< BaseCompare > &	cmpObj
	)

virtual

Allocate value buffers for the table iterator.

Also get a comparison function if undefined. The function freeIterBuf must be called to free the buffers.
