Constructor Detail

JAPMinVersion

public JAPMinVersion(java.io.File a_fileRootNode)
              throws java.lang.Exception

Creates a new JAPMinVersion from XML description load from local filesystem.

Parameters:

a_fileJapMinVersion - The XML file containing the root node of the XML structure of this JAPMinVersion ('Jap' node).

Throws:

java.lang.Exception

JAPMinVersion

public JAPMinVersion(org.w3c.dom.Element a_japRootNode)
              throws java.lang.Exception

Creates a new JAPMinVersion from XML description received from remote infoservice or local filesystem.

Parameters:

a_japRootNode - The root node of the XML structure of this JAPMinVersion ('Jap' node).

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 ('Jap').

getId

public java.lang.String getId()

Returns the ID for this JAPMinVersion instance. Because there is only one instance in the system, it's always 'JAPMinVersion'.

Specified by:

getId in interface IDistributable

Specified by:

getId in class AbstractDatabaseEntry

Returns:

The ID for this JAPMinVersion.

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

getVersionNumber

public long getVersionNumber()

Returns the time when this mimimum version information was created by the root-of-update-information infoservice. That infoservice will update and propagate the minimum 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 minimum 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 minimum version info entry, if two entries are compared (higher version number -> more recent entry).

getJapSoftware

public ServiceSoftware getJapSoftware()

Returns the included ServiceSoftware information about the minimum required JAP software version.

Returns:

The software information about the minimum JAP software version.

getPostFile

public java.lang.String getPostFile()

This returns the filename (InfoService command), where this JAP minimum required version information is posted at other InfoServices, It's always '/currentjapversion'.

Returns:

The filename where this JAPMinVersion entry is posted at other InfoServices when this entry is forwarded.

getXmlStructure

public org.w3c.dom.Element getXmlStructure()

Returns the XML structure of this minimum version info entry.

Specified by:

getXmlStructure in class AbstractDistributableDatabaseEntry

Returns:

The XML node of this JAPMinVersion entry ('Jap' node).

getPostData

public byte[] getPostData()

Description copied from class: AbstractDistributableDatabaseEntry

This returns the data, which are posted to other InfoServices. It's the whole XML structure of this DBEntry by default but may be overwritten

Specified by:

getPostData in interface IDistributable

Overrides:

getPostData in class AbstractDistributableDatabaseEntry

Returns:

The data, which are posted to other InfoServices when this entry is forwarded.
