Class SMILESReader

java.lang.Object

org.openscience.cdk.io.ChemObjectIO

org.openscience.cdk.io.DefaultChemObjectReader

org.openscience.cdk.io.SMILESReader

All Implemented Interfaces:

Closeable, AutoCloseable, IChemObjectIO, IChemObjectReader, ISimpleChemObjectReader

public class SMILESReader
extends DefaultChemObjectReader

This Reader reads files which has one SMILES string on each line, where the format is given as below:

 COC ethoxy ethane
 

Thus first the SMILES, and then after the first space (or tab) on the line a title that is stored as CDKConstants.TITLE. For legacy comparability the title is also placed in a "SMIdbNAME" property. If a line is invalid an empty molecule is inserted into the container set. The molecule with have the prop IteratingSMILESReader.BAD_SMILES_INPUT set to the input line that could not be read.

For each line a molecule is generated, and multiple Molecules are read as MoleculeSet.

SMILESReader

public SMILESReader(Reader input)

Construct a new reader from a Reader and a specified builder object.

Parameters:

input - The Reader object from which to read structures

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

Reads the content from a XYZ input. It can only return a IChemObject of type IChemFile.

Parameters:

object - class must be of type ChemFile

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
