The following methods are publicly inherited from OEUnaryFunction:

operator() CreateCopy  


bool operator()(const OEChem::OEAtomBase &atom) const

Returns true, if the atom

  • read from a pdb file with the following pdb atom names: HOH, H2O, DOD, D2O, WAT, TIP, SOL, OH2, OD2.
  • has no heavy atom neighbor

otherwise it returns false.


OESystem::OEUnaryFunction<OEChem::OEAtomBase, bool> *CreateCopy() const

Deep copy constructor that returns a copy of the object. The memory for the returned OEIsWater object is dynamically allocated and owned by the caller.

The returned copy should be deallocated using C++ delete operator in order to prevent a memory leak.
