DefaultMigrationInstructionGenerator

public DefaultMigrationInstructionGenerator(MigrationActivityMatcher migrationActivityMatcher)

Method Detail

migrationActivityValidators

public MigrationInstructionGenerator migrationActivityValidators(List<MigrationActivityValidator> migrationActivityValidators)

Description copied from interface: MigrationInstructionGenerator

Sets the list of migration activity validators which validate that a activity is a candidate for the migration.

Specified by:

migrationActivityValidators in interface MigrationInstructionGenerator

Parameters:

migrationActivityValidators - the list of validators to check

Returns:

this generator instance

migrationInstructionValidators

public MigrationInstructionGenerator migrationInstructionValidators(List<MigrationInstructionValidator> migrationInstructionValidators)

Description copied from interface: MigrationInstructionGenerator

Sets the list of migration instruction validators currently used by the process engine. Implementations may use these to restrict the search space.

Specified by:

migrationInstructionValidators in interface MigrationInstructionGenerator

Returns:

this

generate

public ValidatingMigrationInstructions generate(ProcessDefinitionImpl sourceProcessDefinition,
                                                ProcessDefinitionImpl targetProcessDefinition,
                                                boolean updateEventTriggers)

Description copied from interface: MigrationInstructionGenerator

Generate all migration instructions for mapped activities between two process definitions. A activity can be mapped if the MigrationActivityMatcher matches it with an activity from the target process definition.

Specified by:

generate in interface MigrationInstructionGenerator

Parameters:

sourceProcessDefinition - the source process definition

targetProcessDefinition - the target process definiton

Returns:

the list of generated instructions
