Class ReaderFactory

java.lang.Object

org.openscience.cdk.io.ReaderFactory

public class ReaderFactory
extends Object

A factory for creating ChemObjectReaders. The type of reader created is determined from the content of the input. Formats of GZiped files can be detected too. A typical example is:

   StringReader stringReader = "<molecule/>";
   ChemObjectReader reader = new ReaderFactory().createReader(stringReader);

Constructor Details

ReaderFactory

public ReaderFactory()

Constructs a ReaderFactory which tries to detect the format in the first 65536 chars.

ReaderFactory

public ReaderFactory(int headerLength)

Constructs a ReaderFactory which tries to detect the format in the first given number of chars.

Parameters:

headerLength - length of the header in number of chars

Method Details

registerFormat

public void registerFormat(IChemFormatMatcher format)

Registers a format for detection.

getFormats

public List<IChemFormatMatcher> getFormats()

createReader

public ISimpleChemObjectReader createReader(InputStream input)
                                     throws IOException

Detects the format of the Reader input, and if known, it will return a CDK Reader to read the format, or null when the reader is not implemented.

Returns:

null if CDK does not contain a reader for the detected format.

Throws:

IOException

createReader

public ISimpleChemObjectReader createReader(Reader input)
                                     throws IOException

Detects the format of the Reader input, and if known, it will return a CDK Reader to read the format. This method is not able to detect the format of gziped files. Use createReader(InputStream) instead for such files.

Throws:

IOException
