Constructor Detail

JAPVersionInfo

public JAPVersionInfo(org.w3c.dom.Element a_jnlpRootNode,
                      int a_versionInfoType)
               throws java.lang.Exception

Creates a new JAP version info out of a JNLP file.

Parameters:

a_jnlpRootNode - The root node of the JNLP document.

a_versionInfoType - The type of the JAPVersionInfo (release / development), see the constants in this class.

Throws:

java.lang.Exception

Method Detail

getXmlElementName

public static java.lang.String getXmlElementName()

Returns the name of the XML root element used by this class.

Returns:

The name of the XML root element used by this class ('jnlp').

getRecommendedUpdate

public static JAPVersionInfo getRecommendedUpdate(java.lang.String a_currentVersion,
                                                  boolean a_bStable)

isJavaVersionStillSupported

public boolean isJavaVersionStillSupported()

getSupportedJavaVersion

public java.lang.String getSupportedJavaVersion()

getId

public java.lang.String getId()

Returns the ID of this version information. It's the filename where this version info is available on the infoservice ('/japRelease.jnlp' or '/japDevelopment.jnlp' depending on the type of this version info)

Specified by:

getId in interface IDistributable

Specified by:

getId in class AbstractDatabaseEntry

Returns:

The ID of this version info.

getVersionNumber

public long getVersionNumber()

Returns the time when this version information was created by the root-of-update-information infoservice. That infoservice will update and propagate the version info periodically even if nothing has changed. Attention: The version number returned here is only necessary for message exchange between the infoservices and is completely independent from the version number of the JAP version described in this version info. Don't mix up those two version numbers.

Specified by:

getVersionNumber in class AbstractDatabaseEntry

Returns:

A version number which is used to determine the more recent version info entry, if two entries are compared (higher version number -> more recent entry).

getLastUpdate

public long getLastUpdate()

Description copied from class: AbstractDatabaseEntry

Returns the time in milliseconds when this db entry was created from the origin instance. Never (!) insert the local creation time here, as this will DoS the InfoServices in an endless loop.

Specified by:

getLastUpdate in class AbstractDatabaseEntry

Returns:

the time in milliseconds when this db entry was created from the origin instance

getJapVersion

public java.lang.String getJapVersion()

Returns the JAP software version described by this version info structure.

Returns:

The JAP software version described in this JAPVersionInfo.

getDate

public java.util.Date getDate()

Returns the release date of the JAP software described in this version info structure.

Returns:

The release date of the JAP software described in this JAPVersionInfo.

getCodeBase

public java.net.URL getCodeBase()

Returns the URL of the server, where the corresponding JAP software can be downloaded from.

Returns:

The URL of the download server for the JAP software described in this version info structure.

getJAPJarFileName

public java.lang.String getJAPJarFileName()

Returns the filename of the JAP file on the download server.

Returns:

The filename where the JAP software described in this JAPVersionInfo is available on the download server.

getPostFile

public java.lang.String getPostFile()

This returns the filename (InfoService command), where this JAPVersionInfo entry is posted at other InfoServices. Depending on the type of this version info, it's '/japRelease.jnlp' or 'japDevelopment.jnlp'. This method returns the same value as the getId() method of this instance.

Returns:

The filename where this version information is posted at other infoservices when this entry is forwarded.

getXmlStructure

public org.w3c.dom.Element getXmlStructure()

Returns the XML structure for this version info entry.

Specified by:

getXmlStructure in class AbstractDistributableDatabaseEntry

Returns:

The XML node of this JAPVersionInfo entry (jnlp node).
