public class IlvRandomLayoutGrapherProperty
extends IlvBasicLinkStyleLayoutGrapherProperty

The class IlvRandomLayoutGrapherProperty allows you to store the global settings of an instance of IlvRandomLayout as a named property in the grapher. This is used by IlvGrapherPropertyAdapter.saveParametersToNamedProperties(IlvGraphLayout, boolean) which is an auxiliary to be used before IlvGrapher.write(IlvOutputStream) if you want to store layout parameter settings in .ivl files.

Since:

JViews 3.5

Constructor Detail

IlvRandomLayoutGrapherProperty

public IlvRandomLayoutGrapherProperty(String name,
                                      IlvRandomLayout layout,
                                      boolean withDefaults)

Creates a new IlvRandomLayoutGrapherProperty 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).

IlvRandomLayoutGrapherProperty

public IlvRandomLayoutGrapherProperty(IlvRandomLayoutGrapherProperty source)

Creates a new IlvRandomLayoutGrapherProperty by copying an existing one.

Parameters:

source - The origin of the copy.

IlvRandomLayoutGrapherProperty

public IlvRandomLayoutGrapherProperty(IlvInputStream stream)
                               throws IOException,
                                      IlvReadFileException

Creates a new IlvRandomLayoutGrapherProperty from an IlvInputStream.

Parameters:

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

Throws:

IlvReadFileException - if an error occurs while reading.

IOException

IlvRandomLayoutGrapherProperty

protected IlvRandomLayoutGrapherProperty(IlvInputStream stream,
                                         boolean fromSubclass)
                                  throws IOException,
                                         IlvReadFileException

Creates a new IlvRandomLayoutGrapherProperty from an IlvInputStream. This method is for internal purpose.

Parameters:

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

fromSubclass - Whether this constructor is called from a subclass.

Throws:

IlvReadFileException - if an error occurs while reading.

IOException

Since:

JViews 8.8

Method Detail

readProperties

protected boolean readProperties(IlvInputStream stream)
                          throws IOException,
                                 IlvReadFileException

Reads the properties from an IlvInputStream. This method is for internal purpose.

Overrides:

readProperties in class IlvBasicLinkStyleLayoutGrapherProperty

Parameters:

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

Throws:

IlvReadFileException - if an error occurs while reading.

IOException

Since:

JViews 8.8

copy

public IlvNamedProperty copy()

Copies the named property.

Overrides:

copy in class IlvBasicLinkStyleLayoutGrapherProperty

isPersistent

public boolean isPersistent()

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

Overrides:

isPersistent in class IlvBasicLinkStyleLayoutGrapherProperty

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 IlvBasicLinkStyleLayoutGrapherProperty

Parameters:

stream - The output stream.

Throws:

IOException - standard IO error.

transfer

public void transfer(IlvGraphLayout graphLayout)

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

Overrides:

transfer in class IlvBasicLinkStyleLayoutGrapherProperty

Parameters:

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

dispose

public void dispose(IlvGrapherPropertyAdapter adapter)

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

Overrides:

dispose in class IlvBasicLinkStyleLayoutGrapherProperty

Parameters:

adapter - The grapher property adapter.

Since:

JViews 8.8
