unsigned Fields (    )  const [inline]

Get number of fields in each record Returns: number of fields Definition at line 131 of file dbf.h.

const string & FieldName (  unsigned    num )  const

Get name of field Parameters: num  number of field (range: 0..(Fields()-1)) Returns: string containing name of field Exceptions: Error  if index out of range Definition at line 194 of file dbf.cpp.

unsigned Records (    )  const [inline]

Get number of records stored in database Returns: number of records Definition at line 142 of file dbf.h.

bool nextRecord (    )  [inline]

Proceed to next record Returns: true if successful Definition at line 146 of file dbf.h.

bool gotoRecord (  unsigned    index )  [inline]

Goto specific record Parameters: index  index of record (range: 0..(Records()-1)) Returns: true if successful Definition at line 155 of file dbf.h.

string FieldContent (  const std::string &    fieldName, bool    crop = true )  const

Read content of current record Parameters: fieldName  name of field to read See also: FieldName (to get legal values for fieldName) Parameters: crop  if true -> crop leading and trailing spaces from result (defaults to true) Returns: string containing content Exceptions: Error  if fieldName is illegal Definition at line 205 of file dbf.cpp.
