Class EpctoolsXmlFile

java.lang.Object
  de.upb.swt.epctools.plugin.editor.EpctoolsXmlFile

public class EpctoolsXmlFile
extends java.lang.Object

This class reads an epml2.0 file and creates the corresponding EPC instance. After loading an epml file, the EpctoolsXmlFile instance should not be discarded because it is needed to save the xml after the content has been edited (because the xml loading function remembers the structure of the xml file (e.g. comments) and preserves the information when writing the new file).

Method Detail

createEmptyDocument

private org.w3c.dom.Document createEmptyDocument()

This function returns an empty epml document.

createModel

private void createModel(org.w3c.dom.Document dom)

createArcs

private void createArcs(org.w3c.dom.Document dom,
                        float scaling_factor)

getEPC

public EPC getEPC()

This function returns the computed EPC model instance after initialization.

Returns:

The EPC corresponding to the input file

save

public java.io.ByteArrayOutputStream save(EPC epc)

This function saves an EPC model to hard disk. This method uses the old dom structure to save user added comments etc..

Parameters:

epc -

getVectorFromNodeList

public static java.util.Vector getVectorFromNodeList(org.w3c.dom.NodeList list)

This function converts a NodeList to a Vector. The returned Vector contains Nodes only!

addNodeListToVector

public static java.util.Vector addNodeListToVector(java.util.Vector v,
                                                   org.w3c.dom.NodeList list)

This function adds all elements from list to v. The returned Vector contains Nodes only, if the parameter v contains Nodes only.
