Class IlvRandomLabelLayoutManagerProperty

java.lang.Object

ilog.views.IlvNamedProperty

ilog.views.graphlayout.labellayout.IlvLabelLayoutManagerProperty

ilog.views.graphlayout.labellayout.random.IlvRandomLabelLayoutManagerProperty

All Implemented Interfaces:

IlvPersistentObject, Serializable

public class IlvRandomLabelLayoutManagerProperty
extends IlvLabelLayoutManagerProperty

The class IlvRandomLabelLayoutManagerProperty allows you to store the global settings of an instance of IlvRandomLabelLayout as a named property in the manager. This is used by IlvDefaultLabelingModel.saveParametersToNamedProperties(IlvLabelLayout, boolean) which is an auxiliary to be used before IlvManager.write(IlvOutputStream) if you want to store layout parameter settings in .ivl files.

Since:

JViews 5.0

Constructor Detail

IlvRandomLabelLayoutManagerProperty

public IlvRandomLabelLayoutManagerProperty(String name,
                                           IlvRandomLabelLayout layout,
                                           boolean withDefaults)

Creates a new IlvRandomLabelLayoutManagerProperty that stores layout parameter settings of the layout.

Parameters:

name - The name of the property.

layout - The layout instance to be stored.

withDefaults - If true, the layout property is always persistent. If false, it is persistent only if nondefault parameter settings exist (that is, if the the property is saved to an .ivl file, the default parameter settings are not saved).

IlvRandomLabelLayoutManagerProperty

public IlvRandomLabelLayoutManagerProperty(IlvRandomLabelLayoutManagerProperty source)

Creates a new IlvRandomLabelLayoutManagerProperty by copying an existing one.

Parameters:

source - The origin of the copy.

IlvRandomLabelLayoutManagerProperty

public IlvRandomLabelLayoutManagerProperty(IlvInputStream stream)
                                    throws IOException,
                                           IlvReadFileException

Creates a new IlvRandomLabelLayoutManagerProperty from an IlvInputStream.

Parameters:

stream - The input stream from which the property must be read.

Throws:

IlvReadFileException - if an error occurs while reading.

IOException

Method Detail

copy

public IlvNamedProperty copy()

Copies the named property.

Overrides:

copy in class IlvLabelLayoutManagerProperty

isPersistent

public boolean isPersistent()

Returns true if the property must be saved to an .ivl file.

Overrides:

isPersistent in class IlvLabelLayoutManagerProperty

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the property to the output stream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvLabelLayoutManagerProperty

Parameters:

stream - The output stream.

Throws:

IOException - standard IO error.

transfer

public void transfer(IlvLabelLayout labelLayout)

Transfers the layout parameter settings stored in this named property back to the input layout.

Overrides:

transfer in class IlvLabelLayoutManagerProperty

Parameters:

labelLayout - The layout instance whose parameters are to be recovered from this instance.

dispose

public void dispose(IlvDefaultLabelingModel model)

Disposes of the property and releases any resources that it is using. This is called if the property was loaded and removed from the manager.

Overrides:

dispose in class IlvLabelLayoutManagerProperty

Parameters:

model - The labeling model.
