Method Detail

getContextFunctionNames

public String[] getContextFunctionNames()

Returns {"mol", "fingerprint"}. This is the accessor function name for getting the molecule.

Specified by:

getContextFunctionNames in interface ChemContext

Returns:

{"mol", "fingerprint"}

callback

public Object callback(String method,
              Object arg)

Implements CallbackIface. Returns null for unimplemented callbacks. Implemented callbacks:

method	arg	return value
"mol"	null	the input molecule
"fingerprint"	null	the input molecule fingerprint

Specified by:

callback in interface ChemContext

Specified by:

callback in interface chemaxon.marvin.util.CallbackIface

Parameters:

method - is the accessor method name

arg - is the accessor method argument (the JEP parameter stack as null, a single parameter object or a parameter object array depending on the number of parameters on the stack)

Returns:

the context element

setMolecule

public void setMolecule(Molecule mol)

Sets the input molecule.

Parameters:

mol - is the input molecule

getMolecule

public Molecule getMolecule()

Returns the input molecule.

Returns:

the input molecule

setFingerprint

public void setFingerprint(int[] fingerprint)

Sets the fingerprint of the input molecule.

Parameters:

fingerprint - is the fingerprint

getFingerprint

public int[] getFingerprint()

Returns the input molecule fingerprint.

Returns:

the input molecule fingerprint

getFingerprint

protected int[] getFingerprint(Object arg)

Returns the input molecule fingerprint if argument is the input molecule, null otherwise.

Parameters:

arg - is the argument to be checked against the input molecule

Returns:

the input molecule fingerprint or null

clear

public void clear()

Clears the context.

Specified by:

clear in interface ChemContext
