Class AbstractBusinessDomainMapper<B extends BusinessDomainObject,P extends Persistable>

java.lang.Object

de.seggebaeing.sqlanalyzer.logic.domainmapper.AbstractBusinessDomainMapper<B,P>

Type Parameters:

B - business domain object type

P - persistable DTO type

All Implemented Interfaces:

BusinessDomainMapper<B,P>

Direct Known Subclasses:

GeneratedQueryMapper, LLMMapper, PromptMapper, PromptTypeMapper, SampleQueryMapper

public abstract class AbstractBusinessDomainMapper<B extends BusinessDomainObject,P extends Persistable>
extends Object
implements BusinessDomainMapper<B,P>

Abstract base for bidirectional mapping between business domain objects (BDOs) and de.seggebaeing.sqlanalyzer.persistence DTOs.

Maintains identity-preserving caches in both directions to avoid duplicate mappings (BDO→DTO and DTO→BDO). Provides initialize(Supplier) to inject an ID supplier required by concrete mappers, and convenience methods putIntoMaps(B, P) / putIntoMaps(P, B) to register paired objects.

1.0

Field Details

cacheMapBDOtoDTO

protected final Map<B extends BusinessDomainObject,P extends Persistable> cacheMapBDOtoDTO

Identity cache mapping BDO → DTO to reuse mapped instances (not thread-safe).

cacheMapDTOtoBDO

protected final Map<P extends Persistable,B extends BusinessDomainObject> cacheMapDTOtoBDO

Identity cache mapping DTO → BDO to reuse mapped instances (not thread-safe).

idSupplier

protected Supplier<Integer> idSupplier

Supplier for generating new IDs; set via initialize(Supplier). Defaults to a lambda that throws an illegal state exception if used before initialization.

Constructor Details

AbstractBusinessDomainMapper

public AbstractBusinessDomainMapper()

Method Details

putIntoMaps

protected void putIntoMaps(B bdo,
 P dto)

Registers a mapped pair in both caches (BDO→DTO and DTO→BDO). Requires non-null arguments.

Parameters:

bdo - the business object

dto - the corresponding DTO

Throws:

NullPointerException - if any of the args are null

putIntoMaps

protected void putIntoMaps(P dto,
 B bdo)

Registers a mapped pair in both caches (DTO→BDO and BDO→DTO). Delegates to putIntoMaps(B, P).

Parameters:

dto - the DTO

bdo - the corresponding business object

initialize

public void initialize(Supplier<Integer> idSupplier)

Initializes this mapper with a supplier for allocating new IDs.

Specified by:

initialize in interface BusinessDomainMapper<B extends BusinessDomainObject,P extends Persistable>

Parameters:

idSupplier - non-null supplier of unique IDs

Throws:

NullPointerException - if idSupplier is null
