Method Detail

getModuleMetadata

<M extends ModuleMetadata> M getModuleMetadata(RuntimeModule module)

Get the metadata of a module that has previously been presisted.

Type Parameters:

M - type of the metadata.

Parameters:

module - to get metadata for.

getModuleMetadata

<M extends ModuleMetadata> M getModuleMetadata(String moduleId)

Get the metadata of a module that has previously been presisted.

Type Parameters:

M - type of the metadata.

Parameters:

moduleId - to get metadata for.

Returns:

module metadata, null if no such metadata exists. This happens, for example, when a module has never been registered and/or run before.

persistModuleMetadata

<M extends ModuleMetadata> void persistModuleMetadata(RuntimeModule module,
                                                      M metadata)

Persist metadata of a module.

Type Parameters:

M - type of the metadata.

Parameters:

module - for which to persist metadata.

metadata - to persist.

persistModuleMetadata

<M extends ModuleMetadata> void persistModuleMetadata(String moduleId,
                                                      M metadata)

Persist metadata of a module.

Type Parameters:

M - type of the metadata.

Parameters:

moduleId - for which to persist metadata.

metadata - to persist.

getAllModuleIds

Set<String> getAllModuleIds()

Get IDs of all modules, for which metadata has been persisted by this repository.

Returns:

IDs of all modules.

removeModuleMetadata

void removeModuleMetadata(String moduleId)

Remove persisted metadata for a module.

Parameters:

moduleId - ID of the module for which to remove previously persisted metadata. Nothing happens if no such metadata exists.
