Class SimpleBend

java.lang.Object

com.yworks.yfiles.graph.SimpleBend

All Implemented Interfaces:

IBend, ILookup, IModelItem, ITagOwner

public class SimpleBend
extends Object
implements IBend

A simple mutable implementation of the IBend interface that can be used stand-alone.

Note that this class is not the one used as the default implementation of a DefaultGraph's IBends and casting them to SimpleBend will fail. Instances of this class can be used without an accompanying graph instance. All of the properties are mutable. An example of a possible use case would be the rendering of a SimpleEdge with bends into a graphics context: Simply create two SimpleNodes, a SimpleEdge to connect the two nodes and add instances of this class to the edge's Bends model. Then render the edge.

Constructor Detail

SimpleBend

public SimpleBend(IEdge owner,
                  IPoint location)

Initializes a new instance of the SimpleBend class using the given owner and location.

Parameters:

owner - The owner of the bend.

location - The bend's location.

Method Detail

getLocation

public final IPoint getLocation()

Gets the location of this bend.

Specified by:

getLocation in interface IBend

Returns:

The Location.

See Also:

getX(), getY(), setLocation(IPoint)

getLookupImplementation

public final ILookup getLookupImplementation()

Gets the ILookup implementation used for calls to lookup(Class) on this instance.

Returns:

The LookupImplementation.

See Also:

setLookupImplementation(ILookup)

getOwner

public final IEdge getOwner()

Description copied from interface: IBend

Returns the edge this bend instance belongs to.

This implies that Owner.Bends contains this instance.

Specified by:

getOwner in interface IBend

Returns:

The Owner.

getTag

public final Object getTag()

Description copied from interface: ITagOwner

Gets the tag associated with this instance.

The implementation itself does not normally depend on the tag associated with it. It serves as storage for the object only.

Specified by:

getTag in interface ITagOwner

Returns:

The user object associated with this instance.

See Also:

ITagOwner.setTag(Object)

getX

public final double getX()

Gets the current x coordinate of this bend.

This delegates to the Location instance.

Returns:

The value of Location.X

getY

public final double getY()

Gets the current y coordinate of this bend.

This delegates to the Location instance.

Returns:

The value of Location.Y

lookup

public <TLookup> TLookup lookup(Class<TLookup> type)

Description copied from interface: ILookup

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.

Specified by:

lookup in interface ILookup

Parameters:

type - the type for which an instance shall be returned

Returns:

an instance that is assignable to type or null

setLocation

public final void setLocation(IPoint value)

Sets the location of this bend.

Parameters:

value - The Location to set.

See Also:

getX(), getY(), getLocation()

setLookupImplementation

public final void setLookupImplementation(ILookup value)

Sets the ILookup implementation used for calls to lookup(Class) on this instance.

Parameters:

value - The LookupImplementation to set.

See Also:

getLookupImplementation()

setOwner

public final void setOwner(IEdge value)

Returns the edge this bend instance belongs to.

This implies that Owner.Bends contains this instance.

Parameters:

value - The Owner to set.

See Also:

getOwner()

setTag

public final void setTag(Object value)

Description copied from interface: ITagOwner

Sets the tag associated with this instance.

The implementation itself does not normally depend on the tag associated with it. It serves as storage for the object only.

Specified by:

setTag in interface ITagOwner

Parameters:

value - The user object associated with this instance.

See Also:

ITagOwner.getTag()
