Class AllChemCompProvider

java.lang.Object

org.biojava.nbio.structure.io.mmcif.AllChemCompProvider

All Implemented Interfaces:

Runnable, ChemCompProvider

public class AllChemCompProvider
extends Object
implements ChemCompProvider, Runnable

A ChemComp provider that downloads and caches the components.cif file from the wwPDB site. It then loads all chemical components at startup and keeps them in memory. This provider is not used as a default since it is slower at startup and requires more memory than the DownloadChemCompProvider that is used by default.
