Getting and Setting functions by Locator

Functions
int	Db::getLocNumber (const ELoc &loctype) const
bool	Db::hasLocVariable (const ELoc &loctype) const
double	Db::getLocVariable (const ELoc &loctype, int iech, int item) const
void	Db::setLocVariable (const ELoc &loctype, int iech, int item, double value)
void	Db::updLocVariable (const ELoc &loctype, int iech, int item, const EOperator &oper, double value)

Detailed Description

Various functions for accessing fields of the Db using the locator designation. They use the argument 'loctype' which refers to the Locator type (see ELoc enumeration). In most cases, they also refer to 'item' i.e. the rank (0 based) for the target locator.

Parameters

loctype	Target locator
iech	Target sample (0 based)
item	Rank of the 'loctype' locator (0 based)
oper	Type of operation 0 : New = New + Old 1 : New = New * Old 2 : New = New - Old 3 : New = Old / New 4 : New = New (only if old is defined) 5 : New = MAX(New, Old) 6 : New = MIN(New, Old)
value	Assigned value

Function Documentation

int Db::getLocNumber

(

const ELoc &

loctype

)

const

Returns the number of fields corresponding to the target locator present in the Db

Returns

Number of fields

double Db::getLocVariable	(	const ELoc &	loctype,
		int	iech,
		int	item
	)		const

Get the value of the field corresponding to the target locator (and its target item) at the target sample

Returns

Returned value

bool Db::hasLocVariable

(

const ELoc &

loctype

)

const

Check if there is at least one field corresponding to the target locator

Returns

TRUE if at least one field corresponds to 'loctype' locator; FALSE otherwise

void Db::setLocVariable	(	const ELoc &	loctype,
		int	iech,
		int	item,
		double	value
	)

Set the value of the field corresponding to the target locator (and its target item) at the target sample

void Db::updLocVariable	(	const ELoc &	loctype,
		int	iech,
		int	item,
		const EOperator &	oper,
		double	value
	)

Update the value of the field corresponding to the target locator (and its target item) at the target sample
