Methods

Public methods

• pivot_format$new()

• pivot_format$clone()

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)

Arguments

id
