Method Details

getHighestVersion

public long getHighestVersion()

Gets the highest version of a resource. This is the highest version we've ever known. There is no guarantee that a resource with this version still exists in the state. It could've been deleted. We need to track this version so we don't ever reuse version numbers after a resource has been deleted.

Returns:

the highest version we've ever known for this resource

setHighestVersionIfHigher

public VersionInfo setHighestVersionIfHigher(long version)

getLatestVersion

public Long getLatestVersion()

getKnownVersions

public List<Long> getKnownVersions()

findVersionBefore

public Optional<Integer> findVersionBefore(long version)

addKnownVersion

public void addKnownVersion(long version)

removeKnownVersion

public void removeKnownVersion(long version)
