using const IInputValidator *	ValidatorPtr

Public Functions¶

	Name
virtual	~IInputValidator() =default Destroys the input validator.
virtual bool	ValidateUTXOParameters(const UTXOTxParameters & params, const std::string & address, const UTXOManager & utxo_manager) const =0 Validates ownership and structure of the supplied UTXO parameters.
virtual bool	ValidateWitness(const ConsensusSubject & subject, const std::shared_ptr< GeniusTransaction > & tx, const UTXOTxParameters & params, const std::shared_ptr< Blockchain > & blockchain) const =0 Validates the chain-specific witness data associated with a transaction input set.
virtual bool	RequiresConsensusUTXOData() const =0 Indicates whether this validator requires consensus-provided UTXO data.

Public Types Documentation¶

using ValidatorPtr¶

using sgns::IInputValidator::ValidatorPtr = const IInputValidator *;

Public Functions Documentation¶

function ~IInputValidator¶

virtual ~IInputValidator() =default

Destroys the input validator.

function ValidateUTXOParameters¶

virtual bool ValidateUTXOParameters(
    const UTXOTxParameters & params,
    const std::string & address,
    const UTXOManager & utxo_manager
) const =0

Validates ownership and structure of the supplied UTXO parameters.

Parameters:

params UTXO inputs and outputs carried by the transaction.
address Source address expected to own or authorize the inputs.
utxo_manager Local UTXO manager used for ownership and signature checks when required.

Return: True when the parameters are structurally valid for this source chain.

function ValidateWitness¶

virtual bool ValidateWitness(
    const ConsensusSubject & subject,
    const std::shared_ptr< GeniusTransaction > & tx,
    const UTXOTxParameters & params,
    const std::shared_ptr< Blockchain > & blockchain
) const =0

Validates the chain-specific witness data associated with a transaction input set.

Parameters:

subject Consensus subject that carries nonce, witness, and UTXO commitment data.
tx Transaction whose inputs and outputs are being validated.
params UTXO inputs and outputs carried by tx.
blockchain Blockchain service used to resolve producer certificates when required.

Return: True when the witness proves that params are valid for tx.

Reimplemented by: sgns::GeniusInputValidator::ValidateWitness, sgns::MigrationInputValidator::ValidateWitness, sgns::PublicChainInputValidator::ValidateWitness

function RequiresConsensusUTXOData¶

virtual bool RequiresConsensusUTXOData() const =0

Indicates whether this validator requires consensus-provided UTXO data.

Return: True when the validator needs UTXO witness and commitment data from consensus.

Reimplemented by: sgns::GeniusInputValidator::RequiresConsensusUTXOData, sgns::MigrationInputValidator::RequiresConsensusUTXOData, sgns::PublicChainInputValidator::RequiresConsensusUTXOData

function Register¶

static inline void Register(
    const std::string & chain_id,
    ValidatorPtr validator
)

function Get¶

static inline ValidatorPtr Get(
    const std::string & chain_id
)
