org.onosproject.ui.model.topo.UiTopoLayout

public class UiTopoLayout
extends Object

Represents a specific "subset" of the UI model of the network topology that a user might wish to view. Backed by a Region.

These instances include information about which geo-map or grid-layout should be displayed, along with zoom and offset parameters.

Constructor Detail

UiTopoLayout

public UiTopoLayout(UiTopoLayoutId id)

Created a new UI topology layout.

Parameters:

id - layout identifier

Method Detail

isRoot

public boolean isRoot()

Returns true if this layout instance is at the top of the hierarchy tree.

Returns:

true if this is the root layout

id

public UiTopoLayoutId id()

Returns the UI layout identifier.

Returns:

identifier of the layout

toString

public String toString()

Overrides:

toString in class Object

region

public UiTopoLayout region(Region region)

Sets the backing region for this layout. Note that an exception will be thrown if this is the root layout.

Parameters:

region - the backing region

Returns:

self, for chaining

Throws:

IllegalArgumentException - if this is the root layout

region

public Region region()

Returns the backing region with which this layout is associated. Note that this may be null (for the root layout).

Returns:

backing region

regionId

public RegionId regionId()

Returns the identifier of the backing region. If this is the default layout, the null-region ID will be returned, otherwise the ID of the backing region for this layout will be returned; null in the case that there is no backing region.

Returns:

backing region identifier

parent

public UiTopoLayout parent(UiTopoLayoutId parentId)

Sets the identity of this layout's parent. May be null to unset. Note that an exception will be thrown if this is the root layout, since the parent of the root is always itself, and cannot be changed.

Parameters:

parentId - parent layout identifier

Returns:

self, for chaining

Throws:

IllegalArgumentException - if this instance is the root layout

parent

public UiTopoLayoutId parent()

Returns the parent layout identifier.

Returns:

parent layout identifier

geomap

public UiTopoLayout geomap(String geomap)

Sets the name of the geomap for this layout. This is the symbolic name for a "topojson" file containing a geographic map projection, to be displayed in the topology view, for this layout.

Since the geomap and sprites fields are mutually exclusive, this method will throw an exception if the sprites field is already set.

Parameters:

geomap - the geomap name

Returns:

self, for chaining

Throws:

IllegalArgumentException - if the sprites field is not null

geomap

public String geomap()

Returns the symbolic name for the geomap for this layout.

Returns:

name of geomap

sprites

public UiTopoLayout sprites(String sprites)

Sets the name of the sprites definition for this layout. This is the symbolic name for a definition of sprites, which render as a symbolic background (e.g. a campus, or floor plan), to be displayed in the topology view, for this layout.

Since the geomap and sprites fields are mutually exclusive, this method will throw an exception if the geomap field is already set.

Parameters:

sprites - the sprites definition name

Returns:

self, for chaining

Throws:

IllegalArgumentException - if the geomap field is not null

sprites

public String sprites()

Returns the symbolic name for the sprites definition for this layout.

Returns:

name of sprites definition

scale

public UiTopoLayout scale(double scale)

Sets the scale for the geomap / sprite image. Note that the acceptable bounds are from to .

Parameters:

scale - the scale

Returns:

self for chaining

Throws:

IllegalArgumentException - if the value is out of bounds

scale

public double scale()

Returns the scale for the geomap / sprite image.

Returns:

the scale

offsetX

public UiTopoLayout offsetX(double offsetX)

Sets the x-offset value.

Parameters:

offsetX - x-offset

Returns:

self, for chaining

offsetX

public double offsetX()

Returns the x-offset value.

Returns:

the x-offset

offsetY

public UiTopoLayout offsetY(double offsetY)

Sets the y-offset value.

Parameters:

offsetY - y-offset

Returns:

self, for chaining

offsetY

public double offsetY()

Returns the y-offset value.

Returns:

the y-offset
