renderProperties

public void renderProperties(HTMLNode alertNode)

brokenDependencies

public boolean brokenDependencies()

cleanupDependencies

public void cleanupDependencies()

addDependency

public void addDependency(byte[] expectedHash,
                          java.io.File filename)

Called by cleanup with the dependencies we can serve for the current version.

Parameters:

expectedHash - The hash of the file's contents, which is also listed in the dependencies file.

multiFileReplaceReadyToDeploy

public void multiFileReplaceReadyToDeploy(freenet.node.updater.MainJarDependenciesChecker.AtomicDeployer atomicDeployer)

A multi-file update (e.g. wrapper update) is ready to deploy. It may need a restart. We may need the user's permission to deploy it, or we may be able to deploy it immediately. The Deployer must call atomicDeployer.deployMultiFileUpdateOffThread() when ready.
