Public methods
Method new()
Initializes pivot format. Method is used to instantiate a pivot_format, given a unique id
,
the name of package used (for information only). A format is then defined by
string expressions (using sprintf
formatting) to read metadata properties
(reader
), one for checking existence of properties (checker
), and an
expression to create metadata objects (constructor
). In case the constructor
is NULL, then no conversion to this metadata format will be possible.
Usage
pivot_format$new(id, pkg, reader = NULL, checker = NULL, constructor = NULL)
