public class MMCIFFileTools
extends Object

Some tools for mmCIF file writing. See http://www.iucr.org/__data/assets/pdf_file/0019/22618/cifguide.pdf CIF categories are represented as a simple bean, typically extending AbstractBean. By default, all fields from the bean are taken as the CIF labels. Fields may be omitted by annotating them as @IgnoreField. The CIF label for a field may be changed (for instance, for fields that are not valid Java identifiers) by defining a function static Map getCIFLabelMap() mapping from the field's name to the correct label.

Method Detail

toLoopMmCifHeaderString

public static String toLoopMmCifHeaderString(String categoryName,
                                             String className)
                                      throws ClassNotFoundException

Produces a mmCIF loop header string for the given categoryName and className. className must be one of the beans in the org.biojava.nbio.structure.io.mmcif.model package

Parameters:

categoryName -

className -

Returns:

Throws:

ClassNotFoundException - if the given className can not be found

toMMCIF

public static String toMMCIF(String categoryName,
                             Object o)

Converts a mmCIF bean (see org.biojava.nbio.structure.io.mmcif.model to a String representing it in mmCIF (single-record) format.

Parameters:

categoryName -

o -

Returns:

getFields

public static Field[] getFields(Class<?> c)

Gets all fields for a particular class, filtering fields annotated with @IgnoreField. As a side effect, calls setAccessible(true) on all fields.

Parameters:

c -

Returns:

getFieldNames

public static String[] getFieldNames(Field[] fields)

Gets the mmCIF record name for each field. This is generally just the name of the field or the value specified by the @CIFLabel annotation. As a side effect, calls setAccessible(true) on all fields.

Parameters:

fields -

Returns:

toMMCIF

public static <T> String toMMCIF(List<T> list,
                                 Class<T> klass)

Converts a list of mmCIF beans (see org.biojava.nbio.structure.io.mmcif.model to a String representing them in mmCIF loop format with one record per line.

Parameters:

list -

Returns:

convertSpaceGroupToSymmetry

public static Symmetry convertSpaceGroupToSymmetry(SpaceGroup sg)

Converts a SpaceGroup object to a Symmetry object.

Parameters:

sg -

Returns:

convertCrystalCellToCell

public static Cell convertCrystalCellToCell(CrystalCell c)

Converts a CrystalCell object to a Cell object.

Parameters:

c -

Returns:

convertAtomToAtomSite

public static AtomSite convertAtomToAtomSite(Atom a,
                                             int model,
                                             String chainName,
                                             String chainId)

Converts an Atom object to an AtomSite object.

Parameters:

a -

model - the model number for the output AtomSites

chainName - the chain identifier (author id) for the output AtomSites

chainId - the internal chain identifier (asym id) for the output AtomSites
