Detailed Description

Class for baseline-based metadata objects, one type of component in SDM data objects.

There are three baseline-based metadata in these objects, the flags, the actual times (the mid-point) and the actual durations. Sharing the same type of tree structure they derive from this BaselineMetadata virtual class, the common base.
An example of how to Access to the baseline-based metadata is given in a test program which uses methods defined in this base but also other methods which are extensions defined in the BaselineFlagsMetada and the ActualTimeDurations classes.

bool sdmbin::BaselineMetadata::wrongBasebandIndex ( int bbIndex ) [protected]

Utility method to check that the input baseband index value in a query is valid or not.

Parameters:

bbIndex The baseband index

Returns:: True or false depending on the upper limit coming from the number of basebands set in the configuartion

bool sdmbin::BaselineMetadata::wrongBasebandIndex ( int bbIndex ) [protected]

Utility method to check that the input baseband index value in a query is valid or not.

Parameters:

bbIndex The baseband index

Returns:: True or false depending on the upper limit coming from the number of basebands set in the configuartion

bool sdmbin::BaselineMetadata::wrongBasebandNum ( int basebandNum ) [protected]

Utility to access the validity of an input basebandNum.

Parameters:

basebandNum Baseband number

Returns:: True if not one-based or exceeds the number of basebands in the configuration, else false

bool sdmbin::BaselineMetadata::wrongBasebandNum ( int basebandNum ) [protected]

Utility to access the validity of an input basebandNum.

Parameters:

basebandNum Baseband number

Returns:: True if not one-based or exceeds the number of basebands in the configuration, else false

bool sdmbin::BaselineMetadata::wrongPolProductIndex	(	int	ppIndex,
		int	bbIndex,
		int	antIndex_i,
		int	antIndex_j
	)		`[protected]`

Utility method to check that the input set of index values in a query is valid or not.

Parameters:

ppIndex	The polarization product index
bbIndex	The baseband index
antIndex_i	The antenna index for antenna i
antIndex_j	The antenna index for antenna j

Returns:: True or false depending on the upper limit for each of these items. Note that ppIndex is a function of the baseband index.
