Detailed Description

template<typename DataType>
class DataBuilder< DataType >

Abstract base class for data builder class. The derived classes of this base class represent the various types of tables in the database. Each derived class provides the necessary specialised implementation particular to its corresponding table type. The design of this class was inspired by the "Builder" design pattern

Constructor & Destructor Documentation

template<typename DataType>

DataBuilder< DataType >::DataBuilder ( ) [inline]

Constructor.

template<typename DataType>

virtual DataBuilder< DataType >::~DataBuilder ( ) [inline, virtual]

Virtual destructor.

Member Function Documentation

template<typename DataType>

virtual TableData<DataType>* DataBuilder< DataType >::build	(	FitsFile &	fpix,
		FitsFile &	fcat,
		int	fileNo
	)			`[pure virtual]`

Interface definition for the build function. This will return an object corresponding to an instance of the TableData class. The object will be filled with data extracted from the given FitsFile objects. An additional input is the file number in the input list. Note that this function as defined in this class doesn't do anything. The actual implementation details appropriate for a particular type of table are given in the derived sub-classes.

Implemented in Catalog< DataType >, Extension< DataType >, Primary< DataType >, and Provenance< DataType >.
