Interface BioUnitDataProvider

All Known Implementing Classes:

MmCifBiolAssemblyProvider, PDBBioUnitDataProvider, RemoteBioUnitDataProvider

public interface BioUnitDataProvider

Provides access to the data that is needed in order to rebuild the correct biological assembly of a protein. This is probably the simpler approach of accessing the necessary information. There is a second access layer, which is closer to the way the PDB is representing the files, it is defined by the interface RawBioUnitDataProvider.

Method Detail

getBioUnitTransformationList

List<BiologicalAssemblyTransformation> getBioUnitTransformationList(String pdbId,
                                                                  int biolAssemblyNr)

get the data for a particular assembly, counting starts at 1...

Parameters:

pdbId - the PDB ID. E.g. 1STP

biolAssemblyNr - the number of the assembly, the first one is nr 1. 0 refers to the asym unit

Returns:

list of transformations.

getNrBiolAssemblies

int getNrBiolAssemblies(String pdbId)

Returns the number of available biological assemblies.

Parameters:

pdbId - the PDB ID. E.g. 1STP

Returns:

nr of available assemblies.

hasBiolAssembly

boolean hasBiolAssembly(String pdbId)

Does the PDB ID have biological assembly information?

Parameters:

pdbId - the PDB ID. E.g. 1STP

Returns:

boolean flag

getAsymUnit

Structure getAsymUnit(String pdbId)

load the asym unit, but set the info how to re-create the bio unit in the PdbHeader object

Parameters:

pdbId -

Returns:

setAsymUnit

void setAsymUnit(Structure asymUnit)

setAtomCache

void setAtomCache(AtomCache cache)

Set an AtomCache to use when fetching asymmetric units. If null, a new cache will be created with default parameters.

Parameters:

cache -

getAtomCache

AtomCache getAtomCache()

Returns:

The current cache, or null if no cache has been initialized
