Constructor Detail

MMTFFileReader

public MMTFFileReader()

Constructs a new MMTFFileReader, initializing the extensions member variable. The path is initialized in the same way as UserConfiguration, i.e. to system property/environment variable UserConfiguration.PDB_DIR. Both autoFetch and splitDir are initialized to false

MMTFFileReader

public MMTFFileReader(String path)

Constructs a new MMTFFileReader, initializing the extensions member variable. The path is initialized to the given path, both autoFetch and splitDir are initialized to false.

Method Detail

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception

getStructure

public Structure getStructure(InputStream inStream)
                       throws IOException

Description copied from class: LocalPDBDirectory

Handles the actual parsing of the file into a Structure object.

Specified by:

getStructure in class LocalPDBDirectory

Returns:

Throws:

IOException

getFilename

protected String getFilename(String pdbId)

Description copied from class: LocalPDBDirectory

Converts a PDB ID into a filename with the proper extension

Specified by:

getFilename in class LocalPDBDirectory

Returns:

The filename, e.g. "4hhb.pdb.gz"

getSplitDirPath

protected String[] getSplitDirPath()

Description copied from class: LocalPDBDirectory

Location of split files within the directory, as an array of paths. These will be joined with either slashes (for the URL) or the file separator (for directories). The returned results should be constant, to allow for caching.

Specified by:

getSplitDirPath in class LocalPDBDirectory

Returns:

A list of directories, relative to the /pub/pdb directory on the server

getObsoleteDirPath

protected String[] getObsoleteDirPath()

Description copied from class: LocalPDBDirectory

Location of obsolete files within the directory, as an array of paths. These will be joined with either slashes (for the URL) or the file separator (for directories). The returned results should be constant, to allow for caching.

Specified by:

getObsoleteDirPath in class LocalPDBDirectory

Returns:

A list of directories, relative to the /pub/pdb directory on the server
