Method Detail

getBreakPoints

@OpenApi
public final java.util.List<java.awt.Point> getBreakPoints()

Returns break points of the path. The order of break points is from supplier to the client path's end. Use PresentationElementsManager to change the break points for the path.

Returns:

break points list.Points in the list are not cloned, so do not modify them directly. List is unmodifiable.

See Also:

PresentationElementsManager.changePathBreakPoints(com.nomagic.magicdraw.uml.symbols.paths.PathElement, java.util.List)

getAllBreakPoints

@OpenApi
public final java.util.List<java.awt.Point> getAllBreakPoints()

Returns breaks points list with added supplier and client end point in the list as well. Use PresentationElementsManager to change the break points for the path.

Returns:

supplier point + break points + client point. Points in the list are not cloned, so do not modify them directly. List is modifiable.

See Also:

PresentationElementsManager.changePathBreakPoints(com.nomagic.magicdraw.uml.symbols.paths.PathElement, java.util.List)

getSupplierPoint

@OpenApi
public final java.awt.Point getSupplierPoint()

Returns point where path connects supplier end's element.

Returns:

supplier connection point. This method returns not cloned point, so do not modify it directly.

getClientPoint

@OpenApi
public final java.awt.Point getClientPoint()

Returns point where path connects client end's element.

Returns:

client point. This method returns not cloned point, so do not modify it directly.

getClient

@OpenApi
public PresentationElement getClient()

Returns client of the path.

Returns:

client element.

getSupplier

@OpenApi
public PresentationElement getSupplier()

Returns supplier of the path.

Returns:

supplier end element.

isConnectable

@OpenApi
public final boolean isConnectable(@CheckForNull
                                            PresentationElement supplier,
                                            @CheckForNull
                                            PresentationElement client)

Checks if this path can connect given two elements.

Parameters:

supplier - candidate for path's supplier.

client - candidate for path's client.

Returns:

true, if path can connect given elements.

getPointOnPath

@OpenApi
public java.awt.Point getPointOnPath(java.awt.Point supplierPoint,
                                              java.awt.Point clientPoint,
                                              java.util.List<java.awt.Point> breakpoints,
                                              double coefficient)

Parameters:

supplierPoint - supplier end point

clientPoint - client end point

breakpoints - list of breakpoints between supplier and client in that order

coefficient - ratio between 0 and 1 describing position relative to the paths length. Provide 0.5 for middle point.

Returns:

point on path

accept

@OpenApi
public void accept(Visitor visitor)
                     throws java.lang.Exception

Description copied from interface: MDElement

Method accepts visitor, and calls method visit<class name>(this) of visitor . See Visitor pattern for more details.

Specified by:
