Method Details

getPriority

int getPriority()

supports

boolean supports(Database database)

setDatabase

void setDatabase(Database database)

reset

void reset()

init

void init()
   throws DatabaseException

Ensures the change log history container is correctly initialized for use. This method may be called multiple times so it should check state as needed.

Throws:

DatabaseException

upgradeChecksums

void upgradeChecksums(DatabaseChangeLog databaseChangeLog,
 Contexts contexts,
 LabelExpression labels)
               throws DatabaseException

Updates null checksum values

Throws:

DatabaseException

getRanChangeSets

List<RanChangeSet> getRanChangeSets()
                             throws DatabaseException

Throws:

DatabaseException

getRanChangeSets

@Deprecated
default List<RanChangeSet> getRanChangeSets(boolean allowChecksumsUpgrade)
                                     throws DatabaseException

Deprecated.

use getRanChangeSets() instead

This method was created to clear out MD5sum for upgrade purpose but after some refactoring the logic was moved to Update commands and it should have been removed as everywhere it is called only with boolean false, so for core it is the same as getRanChangeSets().

Parameters:

allowChecksumsUpgrade -

Throws:

DatabaseException

getRanChangeSet

RanChangeSet getRanChangeSet(ChangeSet changeSet)
                      throws DatabaseException,
DatabaseHistoryException

Throws:

DatabaseException

DatabaseHistoryException

getRunStatus

ChangeSet.RunStatus getRunStatus(ChangeSet changeSet)
                          throws DatabaseException,
DatabaseHistoryException

Throws:

DatabaseException

DatabaseHistoryException

getRanDate

Date getRanDate(ChangeSet changeSet)
         throws DatabaseException,
DatabaseHistoryException

Returns the date the given changeSet was run. Returns null if changeSet was not null.

Throws:

DatabaseException

DatabaseHistoryException

setExecType

void setExecType(ChangeSet changeSet,
 ChangeSet.ExecType execType)
          throws DatabaseException

Throws:

DatabaseException

removeFromHistory

void removeFromHistory(ChangeSet changeSet)
                throws DatabaseException

Throws:

DatabaseException

getNextSequenceValue

int getNextSequenceValue()
                  throws LiquibaseException

Throws:

LiquibaseException

tag

void tag(String tagString)
  throws DatabaseException

Throws:

DatabaseException

tagExists

boolean tagExists(String tag)
           throws DatabaseException

Throws:

DatabaseException

clearAllCheckSums

void clearAllCheckSums()
                throws LiquibaseException

Throws:

LiquibaseException

destroy

void destroy()
      throws DatabaseException

Throws:

DatabaseException

getDeploymentId

String getDeploymentId()

resetDeploymentId

void resetDeploymentId()

generateDeploymentId

void generateDeploymentId()

isDatabaseChecksumsCompatible

boolean isDatabaseChecksumsCompatible()

This method should return true if all checksums in dbcl table have the same version as {@link liquibase.ChecksumVersion#latest().getVersion()}. This method is used by Update command family in order to know if there are old checksum versions in the database that should be updated or if it can proceed with fast checksum update process. IF your implementation does not validate dbcl table then return false.

Returns:

false if we have checksums different from {@link liquibase.ChecksumVersion#latest().getVersion()} in the dbcl table.

replaceChecksum

default void replaceChecksum(ChangeSet changeSet)
                      throws DatabaseException

By default does nothing to keep compatibility with older versions, but subclasses may like to implement this method to support checksum upgrades.

Throws:

DatabaseException
