/**

This class represents a line primitive which may be used to compose the
|
|
drawing of an electrical element within the element editor. Lines may have
|
|
specific visual ends (e.g. arrows) through the setFirstEndType and
|
|
setSecondEndType methods. Their size can be defined using the
|
|
setFirstEndLength and setSecondEndLength methods. Please note ends are not
|
|
drawn if the required length for their drawing is longer than the line itself.
|
|
In case there is room for a single end only, the first one get priority.
