Method Detail

getNumElectrons

public int getNumElectrons()

Gets the number of electrons the arrow represents.

Returns:

1 or 2

clone

public java.lang.Object clone()

Description copied from class: MObject

Creates a clone.

Overrides:

clone in class MPolyline

Returns:

the clone

getMolObject

public java.lang.Object getMolObject(int i)

Gets the electron source or sink.

Parameters:

i - E_SOURCE or E_SINK

Returns:

getPointRefCount

public int getPointRefCount()

Gets the number of point references.

Overrides:

getPointRefCount in class MPolyline
