Method Detail

createNode

public Node createNode(double x,
                       double y,
                       boolean selected)

Description copied from class: ComponentFactory

Creates a new node.

Specified by:

createNode in class ComponentFactory

Parameters:

x - the x coordinate of the center point of the node

y - the y coordinate of the center point of the node

selected - whether the node shall be selected

Returns:

the newly created Node

createLine

public Line createLine(Node startNode,
                       Node endNode,
                       boolean selected,
                       boolean directed)

Description copied from class: ComponentFactory

Creates a new line

Specified by:

createLine in class ComponentFactory

Parameters:

startNode - the start node for the line

endNode - the end node for the line

selected - whether the line shall be selected

directed - whether the line shall be directed

Returns:

the newly created Line

createLooseLine

public Line createLooseLine(Node startNode,
                            boolean directed)

Creates a line without an end node. This is used while drawing the line (it must exist without a connection while the user draws it from one node to the other).

line - the line which transports the message

forward - whether the message runs in the designated direction of the line

Returns:

the newly created message

getComponentSelection

public Selection getComponentSelection()

Description copied from class: ComponentFactory

Creates a new selection. Note that this needs not be used often.

Specified by:

getComponentSelection in class ComponentFactory

Returns:

the newly created Selection
