Method Detail

getCurrentVersion

public static java.lang.String getCurrentVersion(java.lang.String objectId)

This method fetches the current version of the provided objectId (regardless of the version passed in)

Parameters:

ticket -

objectId -

Returns:

objectId + current version label

isCurrentVersion

public static boolean isCurrentVersion(java.lang.String objectId)

Returns true of objectId ends with CURRENT or equals the result of getLatestVersion

Parameters:

ticket -

objectId -

Returns:

getLatestVersion

public static java.lang.String getLatestVersion(java.lang.String objectId)

This method fetches the latest version of the provided objectId (regardless of the version passed in)

Parameters:

ticket -

objectId -

Returns:

objectId + latest version label

isLatestVersion

public static boolean isLatestVersion(java.lang.String objectId)

Returns true of objectId ends with LATEST or equals the result of getLatestVersion

Parameters:

objectId -

Returns:

getAllVersionIds

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

getVersionByQualifier

public static java.lang.String getVersionByQualifier(java.lang.String objectId,
                                                     java.lang.String versionQualifier)

Helper method that will get the CURRENT or LATEST version of a document

Parameters:

objectId - (can be just the base, or include a version number on it - we will rebuild it, we have the technology)

current - (false if you want CURRENT, true if you want LATEST)

Returns:

objectId + version

getFirstVersionId

public static java.lang.String getFirstVersionId(java.lang.String objectId)

This method returns the original objectId (chron_id) for the objectId provided

Parameters:

objectId -

Returns:

the original objectId

caluculateNextVersionId

public static java.lang.String caluculateNextVersionId(java.lang.String objectId,
                                                       boolean majorVersion)

This method calculates the next version for the provided objectId. It returns the full new objectId including the version label. If the objectId provided does not have a version label this method returns the objectId.

Parameters:

objectId - the objectId to be calculated on

majorVersion - if true will calculate the next major version

Returns:

newObjectId the updated objectId

promoteToMajorVersion

public static java.lang.String promoteToMajorVersion(java.lang.String ticket,
