All Implemented Interfaces:

IlvPersistentObject, Serializable

public class IlvUniformLengthEdgesLayoutLinkProperty
extends IlvBasicLinkStyleLayoutLinkProperty

The class IlvUniformLengthEdgesLayoutLinkProperty allows you to store the settings of an instance of IlvUniformLengthEdgesLayout for an individual link as a named property in the link. 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.

Constructor Detail

IlvUniformLengthEdgesLayoutLinkProperty

public IlvUniformLengthEdgesLayoutLinkProperty(String name,
                                               IlvUniformLengthEdgesLayout layout,
                                               IlvGraphic link,
                                               boolean withDefaults)

Creates a new IlvUniformLengthEdgesLayoutLinkProperty that stores layout parameter settings of the layout for the link.

Parameters:

name - The name of the property.

layout - The layout instance to be stored.

link - The link 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).

IlvUniformLengthEdgesLayoutLinkProperty

public IlvUniformLengthEdgesLayoutLinkProperty(IlvUniformLengthEdgesLayoutLinkProperty source)

Creates a new IlvUniformLengthEdgesLayoutLinkProperty by copying an existing one.

Parameters:

source - The origin of the copy.

IlvUniformLengthEdgesLayoutLinkProperty

public IlvUniformLengthEdgesLayoutLinkProperty(IlvInputStream stream)
                                        throws IOException,
                                               IlvReadFileException

Creates a new IlvUniformLengthEdgesLayoutLinkProperty from an IlvInputStream.

Parameters:

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

Throws:

IlvReadFileException - if an error occurs while reading.

IOException

IlvUniformLengthEdgesLayoutLinkProperty

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

Creates a new IlvUniformLengthEdgesLayoutLinkProperty 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.

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 IlvBasicLinkStyleLayoutLinkProperty

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 IlvBasicLinkStyleLayoutLinkProperty

isPersistent

public boolean isPersistent()

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

Overrides:

isPersistent in class IlvBasicLinkStyleLayoutLinkProperty

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 IlvBasicLinkStyleLayoutLinkProperty

Parameters:

stream - The output stream.
