SmilesParser
public SmilesParser()
Creates a new SmilesParser that doesn't allow SMARTS features to be present in parsed strings. SMARTS features cause an exception. The fragment flag of created molecules is never set.
-
SmilesParser
public SmilesParser(int smartsMode, boolean createSmartsWarnings)
Creates a new SmilesParser that may or may not allow SMARTS features to be present in parsed strings. If smartsMode is SMARTS_MODE_IS_SMILES, then any SMARTS features cause an exception. If smartsMode is SMARTS_MODE_IS_SMARTS, then the input string is considered a SMARTS, e.g. 'CC' is taken as fragment of two non-aromatic carbon atoms connected by a single bond and without any implicit hydrogen atoms. If smartsMode is SMARTS_MODE_IS_GUESS, then molecules is never set.- Parameters:
smartsMode
- one of SMARTS_MODE...createSmartsWarnings
- if true, then getSmartsWarning() may be used after parsing a SMILES or SMARTS

getSmartsWarning

parse
public void parse(StereoMolecule mol, java.lang.String smiles) throws java.lang.Exception
Parses the given smiles into the molecule, creates proper atom coordinates to reflect correct double bond geometries and translates tetrahedral and allene parities into up/down-bonds. SMARTS features are neglected unless setAllowSmartsFeatures(true) was called before parsing.- Parameters:
