Unnamed Group

Index atomUniqueId(const AtomType &atom) const#

Get the unique ID of the atom, this will uniquely reference the atom as long as it exists.

atom – The atom to obtain the unique ID of.

Returns:

The unique identifier for the atom, MaxIndex if the atom is invalid or does not belong to this molecule.

Index atomUniqueId(Index atom) const#

Get the unique ID of the atom, this will uniquely reference the atom as long as it exists.

Parameters:

atom – The atom to obtain the unique ID of.

Returns:

The unique identifier for the atom, MaxIndex if the atom is invalid or does not belong to this molecule.

virtual bool removeBond(const AtomType &atom1, const AtomType &atom2) override#

Remove the specified bond.

Parameters:

Returns:

True on success, false if the bond was not found. This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

virtual bool removeBond(Index atom1, Index atom2) override#

Remove the specified bond.

Parameters:

  • atom1 – One atom in the bond.

  • atom2 – The other atom in the bond.

Returns:

Unnamed Group

Index bondUniqueId(const BondType &bond) const#

Get the unique ID of the bond, this will uniquely reference the bond as long as it exists.

Parameters:

bond – The bond to obtain the unique ID of.

Returns:

The unique identifier for the bond, MaxIndex if the bond is invalid or does not belong to this molecule.

Index bondUniqueId(Index bond) const#

Get the unique ID of the bond, this will uniquely reference the bond as long as it exists.

Parameters:

bond – The bond to obtain the unique ID of.

Returns:

The unique identifier for the bond, MaxIndex if the bond is invalid or does not belong to this molecule.

Public Slots

void emitChanged(unsigned int change)#

Force the molecule to emit the changed() signal.

Parameters:

change – See changed().

Signals

void changed(unsigned int change)#

Indicates that the molecule has changed.

The change variable indicates what has changed, i.e. if change & Atoms == true then atoms were changed in some way, and if change & Removed == true then one or more atoms were removed.

Parameters:

change – Use the MoleculeChange enum to check what has changed.
