Detailed Description

Bond class. An instance of Bond represents a bond between two atoms. There can be only one bond between two atoms (double, triple, etc. bonds are represented using just one bond and an appropriate value for the bond order attribute, see setBondOrder ).

: The "first" and "second" atom are assigned in a unique way: the first atom is always the atom with the lower Handle than the second atom.

: The "state" of a bond is defined by its attributes:

"first atom" ( Bond::first_ )
"second atom" ( Bond::second_ )
"bond name" ( Bond::name_ ): an arbitrary name
"bond order" ( Bond::bond_order_ ): the order, i.e. single, double, triple,...
"bond type" ( Bond::bond_type_ ): covalent, hydrogen bond, etc. to identify non-standard bond types

Bond equality is defined as bond identity. A linear ordering of bonds is defined as the linear order of the Object::Handle s.

Constructor & Destructor Documentation

BALL::Bond::Bond ( )

Default constructor. The state of this bond is:

bond has no first atom (=0)
bond has no second atom (=0)
bond name is the empty string (="")
bond order is unknown (= Bond::ORDER__UNKNOWN )
bond type is unknown (= Bond::TYPE__UNKNOWN )

BALL::Bond::Bond	(	const Bond &	bond,
		bool	deep = `true`
	)

Copy constructor. Calls Bond::createBond . The state of this bond is initialized to the state of bond.

: Note: Deep copying of bonds makes no sense, the parameter deep is therefore ignored. The use of this method is not recommended because it may result in inconcistencies of the whole the kernel data structure. This if for internal use only!

Parameters:

	bond	the bond to be copied
	deep	ignored

See also:: createBond

BALL::Bond::Bond	(	const String &	name,
		Atom &	first,
		Atom &	second,
		Order	order = `BALL_BOND_DEFAULT_ORDER`,
		Type	type = `BALL_BOND_DEFAULT_TYPE`
	)			throw (Exception::TooManyBonds)

Detailed constructor. Calls createBond to create a new bond between the two atoms

Parameters:

	name	name of the constructed bond
	first	first atom of the constructed bond
	second	second atom of the constructed bond
	order	order of the constructed bond
	type	type of the constructed bond

Exceptions:

TooManyBonds

if one of the atom already possesses Atom::MAX_NUMBER_OF_BONDS bonds.

virtual BALL::Bond::~Bond ( ) [virtual]

Destructor. If the bond is connecting two atoms, they are disconnected.

Member Function Documentation

void BALL::Bond::arrangeBonds_ ( ) [private]

virtual void BALL::Bond::clear ( ) [virtual]

Disconnect and reset to default state. Reset the bond attributes to their default values. The state of this bond is:

bond name is the empty string (="")
bond order is unknown (= Bond::ORDER__UNKNOWN )
bond type is unknown (= Bond::TYPE__UNKNOWN )

Reimplemented from BALL::Composite.
