Constructor Detail

SignatureFingerprinter

public SignatureFingerprinter()

Initialize the fingerprinter with a default signature depth of 1.

SignatureFingerprinter

public SignatureFingerprinter(int depth)

Initialize the fingerprinter with a certain signature depth.

Parameters:

depth - The depth of the signatures to calculate.

Method Detail

getParameters

protected List<Map.Entry<String,String>> getParameters()

Description copied from class: AbstractFingerprinter

Base classes should override this method to report the parameters they are configured with.

Overrides:

getParameters in class AbstractFingerprinter

Returns:

The key=value pairs of configured parameters

getBitFingerprint

public IBitFingerprint getBitFingerprint(IAtomContainer atomContainer)
                                  throws CDKException

Description copied from interface: IFingerprinter

Returns the bit fingerprint for the given IAtomContainer.

Specified by:

getBitFingerprint in interface IFingerprinter

Parameters:

atomContainer - IAtomContainer for which the fingerprint should be calculated.

Returns:

the bit fingerprint

Throws:

CDKException - may be thrown if there is an error during aromaticity detection or (for key based fingerprints) if there is a SMARTS parsing error

getRawFingerprint

public Map<String,Integer> getRawFingerprint(IAtomContainer atomContainer)
                                            throws CDKException

Description copied from interface: IFingerprinter

Returns the raw representation of the fingerprint for the given IAtomContainer. The raw representation contains counts as well as the key strings.

Specified by:

getRawFingerprint in interface IFingerprinter

Parameters:

atomContainer - IAtomContainer for which the fingerprint should be calculated.

Returns:

the raw fingerprint

Throws:

CDKException

getSize

public int getSize()

Description copied from interface: IFingerprinter

Returns the size (or length) of the fingerprint.

Specified by:

getSize in interface IFingerprinter

Returns:

the size of the fingerprint

getCountFingerprint

public ICountFingerprint getCountFingerprint(IAtomContainer container)
                                      throws CDKException

Description copied from interface: IFingerprinter

Returns the count fingerprint for the given IAtomContainer.

Specified by:

getCountFingerprint in interface IFingerprinter

Parameters:

container - IAtomContainer for which the fingerprint should be calculated.

Returns:

the count fingerprint

Throws:

CDKException - if there is an error during aromaticity detection or (for key based fingerprints) if there is a SMARTS parsing error.
