Method Detail

getFormat

public IResourceFormat getFormat()

Description copied from interface: IChemObjectIO

Returns the IResourceFormat class for this IO class.

setReader

public void setReader(Reader input)
               throws CDKException

Description copied from interface: IChemObjectReader

Sets the Reader from which this ChemObjectReader should read the contents.

Throws:

CDKException

setReader

public void setReader(InputStream input)
               throws CDKException

Description copied from interface: IChemObjectReader

Sets the InputStream from which this ChemObjectReader should read the contents.

Throws:

CDKException

accepts

public boolean accepts(Class<? extends IChemObject> classObject)

Description copied from interface: IChemObjectIO

Returns whether the given IChemObject can be read or written.

Parameters:

classObject - IChemObject of which is tested if it can be handled.

Returns:

true, if the IChemObject can be handled.

read

public <T extends IChemObject> T read(T object)
                               throws CDKException

Description copied from interface: ISimpleChemObjectReader

Reads an IChemObject of type "object" from input. The constructor of the actual implementation may take a Reader as input to get a very flexible reader that can read from string, files, etc.

Parameters:

object - the type of object to return

Returns:

returns an object of that contains the content (or part) of the input content

Throws:

CDKException - it is thrown if the type of information is not available from the input

readMolecule

public IAtomContainer readMolecule(IChemObjectBuilder builder)
                            throws CDKException

Throws:

CDKException

readConnectionTable

public IAtomContainer readConnectionTable(IChemObjectBuilder builder)
                                   throws CDKException

Throws:

CDKException

readHeader

public String readHeader(IAtomContainer readData)
                  throws CDKException

Returns:

Last line read

Throws:

CDKException - when no file content is detected

readAtomBlock

public void readAtomBlock(IAtomContainer readData)
                   throws CDKException

Reads the atoms, coordinates and charges.

IMPORTANT: it does not support the atom list and its negation!

Throws:

CDKException

readBondBlock

public void readBondBlock(IAtomContainer readData)
                   throws CDKException

Reads the bond atoms, order and stereo configuration.

Throws:

CDKException

readSGroup

public void readSGroup(IAtomContainer readData)
                throws CDKException

Reads labels.

Throws:

CDKException

exhaustStringTokenizer

public String exhaustStringTokenizer(StringTokenizer tokenizer)

readLine

public String readLine()
                throws CDKException

Throws:

CDKException

isReady

public boolean isReady()
                throws CDKException

Throws:

CDKException

close

public void close()
           throws IOException

Description copied from interface: IChemObjectIO

Closes this IChemObjectIO's resources.

Throws:

IOException - when the wrapper IO class cannot be closed.
