public final class RuleBasedTransactionFactory extends Object

RuleBasedTransactionFactory

Rule-based transaction factory: registers named parsing rules (POD / enum / flags / struct / array) and applies them via TransactionDescriptorProcessor. Rules come from the generated Models.POD_FACTORIES registry and typed struct suppliers.

  Description

  void

  addArrayParser(String name)

  Creates an array type parser based on an existing element type parser.

  void

  addPodParser(String name, Function<Object,Object> parser)

  Registers a parser for a POD type.

  void

  addPodParsers(Map<String,Function<Object,Object>> parsers)

  Registers a batch of named value-parse rules — typically a generated Models.POD_FACTORIES registry.

  void

  addStructParser(String name, Supplier<? extends CatbufferType> factory)

  Creates a struct parser (allows nested parsing) over a strongly typed factory reference.

  Object

  createFromFactory(Function<Object,Object> factory, Map<String,Object> descriptor)

  Creates an entity from a descriptor using a factory.

  • RuleBasedTransactionFactory

    public RuleBasedTransactionFactory(Function<Object,Object> typeConverter, Map<String,Function<Object,Object>> typeRuleOverrides)

    Creates a rule-based transaction factory for use with catbuffer generated code.

    Parameters:

    typeConverter - Optional convert to a more appropriate type.

    typeRuleOverrides - Per-rule parser overrides keyed by rule name.

  • RuleBasedTransactionFactory

    public RuleBasedTransactionFactory()

    Creates a rule-based transaction factory without a custom type converter or overrides.

• Method Details

  • addPodParsers

    public void addPodParsers(Map<String,Function<Object,Object>> parsers)

    RuleBasedTransactionFactory.addPodParsers

    Registers a batch of named value-parse rules — typically a generated Models.POD_FACTORIES registry.

    Parameters:

    parsers - Rule name → parse function.

  • addPodParser

    public void addPodParser(String name, Function<Object,Object> parser)

    RuleBasedTransactionFactory.addPodParser

    Registers a parser for a POD type. The parser is replaced by a matching typeRuleOverrides entry when one was supplied for name.

    Parameters:

    name - Rule name (and override key).

    parser - Parse function converting a raw descriptor value into the POD.

  • addStructParser

    public void addStructParser(String name, Supplier<? extends CatbufferType> factory)

    RuleBasedTransactionFactory.addStructParser

    Creates a struct parser (allows nested parsing) over a strongly typed factory reference.

    Parameters:

    name - Class name (rule key).

    factory - Supplier producing a fresh, default-initialized struct instance.

  • addArrayParser

    public void addArrayParser(String name)

    RuleBasedTransactionFactory.addArrayParser

    Creates an array type parser based on an existing element type parser.

    Parameters:

    name - Class name (existing rule key).

  • createFromFactory

    public Object createFromFactory(Function<Object,Object> factory, Map<String,Object> descriptor)

    RuleBasedTransactionFactory.createFromFactory

    Creates an entity from a descriptor using a factory. The descriptor's required type key selects the entity; remaining keys are copied onto it through TransactionDescriptorProcessor.copyTo(org.symbol.sdk.CatbufferType, java.util.List<java.lang.String>).

    Parameters:

    factory - Function that, given the resolved type value, returns a new entity.

    descriptor - Entity descriptor.

    Returns:

    Newly created entity.
