IlvPersistentObject, Serializable

public class IlvTopologicalMeshLayoutNodeProperty
extends IlvBasicLinkStyleLayoutNodeProperty

The class IlvTopologicalMeshLayoutNodeProperty allows you to store the settings of an instance of IlvTopologicalMeshLayout for an individual node as a named property in the node. This is used by IlvGrapherPropertyAdapter.saveParametersToNamedProperties(IlvGraphLayout, boolean) which is an auxiliary to be used before IlvManager.write(IlvOutputStream) if you want to store layout parameter settings in .ivl files.

JViews 3.5

Constructor Detail

IlvTopologicalMeshLayoutNodeProperty

public IlvTopologicalMeshLayoutNodeProperty(String name,
                                            IlvTopologicalMeshLayout layout,
                                            IlvGraphic node,
                                            boolean withDefaults)

Creates a new IlvTopologicalMeshLayoutNodeProperty that stores layout parameter settings of the layout for the node.

Parameters:

name - The name of the property.

layout - The layout instance to be stored.

node - The node whose layout parameters are 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).

IlvTopologicalMeshLayoutNodeProperty

public IlvTopologicalMeshLayoutNodeProperty(IlvTopologicalMeshLayoutNodeProperty source)

Creates a new IlvTopologicalMeshLayoutNodeProperty by copying an existing one.

Parameters:

source - The origin of the copy.

IlvTopologicalMeshLayoutNodeProperty

public IlvTopologicalMeshLayoutNodeProperty(IlvInputStream stream)
                                     throws IOException,
                                            IlvReadFileException

Creates a new IlvTopologicalMeshLayoutNodeProperty from an IlvInputStream.

Parameters:

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

Throws:

IlvReadFileException - if an error occurs while reading.

IOException

IlvTopologicalMeshLayoutNodeProperty

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

Creates a new IlvTopologicalMeshLayoutNodeProperty 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

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 IlvBasicLinkStyleLayoutNodeProperty

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 IlvBasicLinkStyleLayoutNodeProperty

isPersistent

public boolean isPersistent()

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

Overrides:

isPersistent in class IlvBasicLinkStyleLayoutNodeProperty

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 IlvBasicLinkStyleLayoutNodeProperty

Parameters:

stream - The output stream.

transfer

public void transfer(IlvGraphLayout graphLayout,
                     IlvGraphic node)
