Method Detail

getBuildNumber

public java.lang.String getBuildNumber()
Specified by:
getBuildNumber in interface UpgradeTaskInfo
Overrides:
getBuildNumber in class AbstractUpgradeTask
Returns:
The build number that this upgrade is applicable to

getShortDescription

public java.lang.String getShortDescription()
Description copied from interface: UpgradeTaskInfo
A short (<50 chars) description of the upgrade action

Specified by:
getShortDescription in interface UpgradeTaskInfo
Overrides:
getShortDescription in class AbstractUpgradeTask

doUpgrade

public void doUpgrade()
               throws java.lang.Exception
Description copied from interface: UpgradeTask
Perform the upgrade.

Specified by:
doUpgrade in interface UpgradeTask
Throws:
java.lang.Exception

getUniqueConstraintSqlStatements

public static java.util.List<java.lang.String> getUniqueConstraintSqlStatements()

runOnSpaceImport

public boolean runOnSpaceImport()
Description copied from interface: BackupSupport
Returns true if an older Space can't be imported in a new instance without running this task. For example:

Note that tasks don't run on space import yet, so we just reject the import in this case.

Specified by:
runOnSpaceImport in interface BackupSupport

breaksBackwardCompatibility

public boolean breaksBackwardCompatibility()
Description copied from interface: BackupSupport
Returns true if a new export can't be imported in an older instance. Breaking compatibility means a snapshot of the new version will not work at all with the previous version. For example: The best way to test is whether a newer export can be imported (with fully working features) in an older instance.

Specified by:
breaksBackwardCompatibility in interface BackupSupport
