Constructor Details

ProcessDefinitions

public ProcessDefinitions(List<ProcessDefinition<?,?>> definitions)

Register definitions without version migrations. Existing definitions default to version 1.

ProcessDefinitions

public ProcessDefinitions(List<ProcessDefinition<?,?>> definitions,
 List<ProcessDefinitionMigration<?,?,?,?>> migrations)

Register versioned definitions and their deterministic forward migration edges.

Method Details

require

public ProcessDefinition<?,?> require(String key)

Resolve the latest registered version for a stable definition key.

require

public ProcessDefinition<?,?> require(String key,
 int version)

Resolve the exact definition version persisted by an instance.

all

public List<ProcessDefinition<?,?>> all()

Latest definition for each stable key, in registration-key order.

allVersions

public List<ProcessDefinition<?,?>> allVersions()

Every registered definition version, ordered by key registration and ascending version.

versions

public List<ProcessDefinition<?,?>> versions(String key)

Registered versions for one stable definition key, in ascending order.

migrationPath

public List<ProcessDefinitionMigration<?,?,?,?>> migrationPath(String key,
 int storedVersion)

Resolve the deterministic migration chain from a stored version to the latest version.

Throws:

IllegalArgumentException - when the stored version is unknown or no complete path exists

migrationPath

public List<ProcessDefinitionMigration<?,?,?,?>> migrationPath(String key,
 int fromVersion,
 int toVersion)

Resolve a deterministic forward migration chain between two registered versions.

Each source version may have only one outgoing migration, so lookup can never silently choose between competing upgrade routes.
