Inheritance | NodeScaledPortLocationModel Object |
Implements | IPortLocationModel |
IPortLocationModel
for IPort
s
at INode
s that determine the location dynamically using the INode
's
layout
.
Internally the location is stored as the ratio by which the IRectangle.width
and
IRectangle.height
of the INode.layout
need to be scaled to obtain the
offset to the center of the node layout.

|
createParameter | () | method |
public function createParameter(portOwner:IPortOwner, location:IPoint = null):IPortLocationModelParameter
Factory method that creates a parameter for the given port that tries to match the provided location in absolute world coordinates.
Parameters
portOwner:IPortOwner — The port owner that will own the port for which the parameter shall be created.
| |
location:IPoint (default = null ) — The location in the world coordinate system that should be matched as best as possible.
|
IPortLocationModelParameter — A new instance that can be used to describe the location of an IPort at the given
IPortOwner .
|
createScaledParameter | () | method |
public function createScaledParameter(relativeOffset:IPoint):IPortLocationModelParameter
Creates a parameter that uses the given relative offsets.
The offsets will be scaled by the node layouts size and added to the node center to determine the port location.
Parameters
relativeOffset:IPoint — The relative offsets.
|
IPortLocationModelParameter — A new parameter that matches the specification.
|
getContext | () | method |
public function getContext(port:IPort, parameter:IPortLocationModelParameter):ILookup
Provides a lookup context for the given combination of port and parameter.
Parameters
port:IPort — The port to use in the context.
| |
parameter:IPortLocationModelParameter — The parameter to use for the port in the context.

ILookup — An implementation of the ILookup interface that can be used to query additional aspects
of the port/parameter combination.
|
getLocation | () | method |
public function getLocation(port:IPort, modelParameter:IPortLocationModelParameter):IPoint
Calculates the location in form of an IPoint
for a given port using the given model parameter.
Parameters
port:IPort — The port to calculate the location for
| |
modelParameter:IPortLocationModelParameter — A parameter that has been created by this model.
This is typically the parameter that yielded this instance through its
IPortModelParameter.model property.
|
IPoint — An instance that describes the location. This is typically
an instance designed as a flyweight, so clients should not cache the
instance but store the values if they need a snapshot for later use
|
lookup | () | method |
public function lookup(type:Class):Object
Returns an instance that implements the given type or null
.
Typically, this method will be called in order to obtain a different view or
aspect of the current instance. This is quite similar to casting or using
a super type or interface of this instance, but is not limited to inheritance or
compile time constraints. An instance implementing this method is not
required to return non-null
implementations for the types, nor does it
have to return the same instance any time. Also it depends on the
type and context whether the instance returned stays up to date or needs to
be reobtained for subsequent use.
Parameters
type:Class — the type for which an instance shall be returned
|
Object — an instance that is assignable to type or null
