Method Details

getContextFunctionNames

public String[] getContextFunctionNames()

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

Specified by:

getContextFunctionNames in interface ChemContext

Overrides:

getContextFunctionNames in class MolContext

Returns:

{"mol", "fingerprint", "atom"}

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
"atom"	null	the input atom

Specified by:

callback in interface chemaxon.marvin.util.CallbackIface

Specified by:

callback in interface ChemContext

Overrides:

callback in class MolContext

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

setAtom

public void setAtom(int atom)

Sets the input atom.

Parameters:

atom - is the input atom index

getAtom

public int getAtom()

Returns the input atom index.

Returns:

the input atom index

clear

public void clear()

Clears the context.

Specified by:

clear in interface ChemContext

Overrides:

clear in class MolContext
