Package org.rcsb.cif

Class CifOptions

java.lang.Object

org.rcsb.cif.CifOptions

public class CifOptions
extends Object

Allows to set options for CIF writing. Acquire by calling builder(). Pass into CifIO functions. Use white- and blacklist functions to select a subset of categories and/or columns to write. If a value is present in both white- and blacklist, the blacklist values will trump the whitelist.

For now only writer classes will respect these options. They can be passed to reader classes as well, however there are currently no relevant options for CIF reading.
