Class ManualNodeLayout

java.lang.Object

idare.imagenode.internal.Layout.Manual.ManualNodeLayout

All Implemented Interfaces:

DataSetAboutToBeChangedListener, IDAREService, ImageNodeLayout

public class ManualNodeLayout
extends Object
implements ImageNodeLayout, IDAREService

This is a very simplistic Node Layout that originates from a Manual layout generation. removed Datasets will simply be removed from the layout as we don't know what to do with them.

Constructor Detail

ManualNodeLayout

public ManualNodeLayout()

Create an empty layout. only usable when set up.

Method Detail

setupLayout

public void setupLayout(List<DataSetLayoutInfoBundle> alignedlayoutData,
                        List<LayoutComparator> orderedlayoutData)

The assumption is, that the order in the given Vector is the expected order!

Parameters:

alignedlayoutData - the Bundles in the correct alignment (back to front)

orderedlayoutData - the Comparators to obtain the Containerlayouts from. in the correct order (to determine the labels.

isValid

public boolean isValid()

Description copied from interface: ImageNodeLayout

Check whether this AutomaticNodeLayout is valid. A Layout is valid, if its ImageNodeContainer contains at least one DataSet. Thus, by default a newly generated layout is invalid until a DataSet is added.

Specified by:

isValid in interface ImageNodeLayout

Returns:

whether this layout is still valid (i.e. has contaniers to lay out)

writeLayout

public void writeLayout(ObjectOutputStream os)
                 throws IOException

Description copied from interface: ImageNodeLayout

Write all data that is relevant to restore this nodelayout to a ObjectOutputStream

Specified by:

writeLayout in interface ImageNodeLayout

Parameters:

os - The ObjectOutputStream to write the dlayout infromation to

Throws:

IOException - If errors occur with the given stream

readLayout

public boolean readLayout(DataSetManager dsm,
                          ObjectInputStream os,
                          Object currentobject)
                   throws IOException

Description copied from interface: ImageNodeLayout

Read a layout object from an ObjectInputStream given the last object read (which is the first object of the layout)

Specified by:

readLayout in interface ImageNodeLayout

Parameters:

dsm - the DataSetManager to get information about DataSets from.

os - The ObjectInputStream to read from

currentobject - The last object read in the ObjectInputStream provided (the first object of the nodelayout save

Returns:

true, if reading was successful, false if there was a non IOException.

Throws:

IOException - If errors occur with the given stream

getDataSetLabel

public String getDataSetLabel(DataSetLink ds)

Description copied from interface: ImageNodeLayout

Get the label for a specific DataSet used in this layout;

Specified by:

getDataSetLabel in interface ImageNodeLayout

Parameters:

ds - the DataSet to get the label for

Returns:

The String label for the supplied DataSet

getColorsForDataSet

public ColorMap getColorsForDataSet(DataSetLink ds)

Description copied from interface: ImageNodeLayout

Get the ColorMap associated with this DataSet in this AutomaticNodeLayout.

Specified by:

getColorsForDataSet in interface ImageNodeLayout

Parameters:

ds - - The requested Dataset

Returns:

the ColorMap associated with the DataSet in this AutomaticNodeLayout

getDatasetsInOrder

public Vector<? extends DataSetLink> getDatasetsInOrder()

Description copied from interface: ImageNodeLayout

Get the DataSets used in this Layout in the order of labeling

Specified by:

getDatasetsInOrder in interface ImageNodeLayout

Returns:

A Vector of DataSets in the order they were added during the layout process

layoutNode

public void layoutNode(Collection<NodeData> datacollection,
                       org.apache.batik.svggen.SVGGraphics2D svg)

Description copied from interface: ImageNodeLayout

                             org.apache.batik.svggen.SVGGraphics2D svg)

Description copied from interface: ImageNodeLayout

Lay out the legend for a specific set of node data

Specified by:

layoutLegendNode in interface ImageNodeLayout

Parameters:
