(

std::string

)

Given a std::string specifying a field (column) name, return its corresponding field number.

-1 means it's not there

std::string code::dBASEfile::getColumnName

(

size_t

j

)

const

Obtain the jth field name.

float code::dBASEfile::getNumericValue	(	size_t	i,
		size_t	j
	)			const

Returns, as a float, the value of the ith row, jth column, of the table.

The result is undefined if the data is not actually numeric.

std::string code::dBASEfile::getValue	(	size_t	i,
		size_t	j
	)			const

Returns the value of the ith row , jth column of the table.

(

size_t

j

)

const

Is the jth column numeric?

int code::dBASEfile::numColumns

(

)

const

Number of columns in the table.

int code::dBASEfile::numRows

(

)

const

Number of rows in the table.

void code::dBASEfile::setNumericValue	(	size_t	i,
