StakeVoteDelegationCert

class cometa.certificates.stake_vote_delegation_cert.StakeVoteDelegationCert(ptr)[source]

Bases: object

Represents a combined stake and vote delegation certificate.

This certificate allows delegating both stake (to a pool) and voting power (to a DRep) in a single certificate.

__init__(ptr)[source]

__exit__(exc_type, exc_val, exc_tb)[source]

Return repr(self).

classmethod new(credential, pool_key_hash, drep)[source]

Creates a new stake and vote delegation certificate.

Parameters:

credential (Credential) – The stake credential delegating stake and voting power.
pool_key_hash (Blake2bHash) – The hash of the pool’s operator key to delegate stake to.
drep (DRep) – The DRep to delegate voting power to.

Returns:

A new StakeVoteDelegationCert instance.

Raises:

CardanoError – If creation fails.

Return type:

StakeVoteDelegationCert

classmethod from_cbor(reader)[source]

Deserializes a StakeVoteDelegationCert from CBOR data.

Parameters:: reader (CborReader) – A CborReader positioned at the certificate data.
Returns:: A new StakeVoteDelegationCert deserialized from the CBOR data.
Raises:: CardanoError – If deserialization fails.
Return type:: StakeVoteDelegationCert

to_cbor(writer)[source]

Serializes the certificate to CBOR format.

Parameters:: writer (CborWriter) – A CborWriter to write the serialized data to.
Raises:: CardanoError – If serialization fails.
Return type:: None

property credential: Credential

The stake credential delegating stake and voting power.

property pool_key_hash: Blake2bHash

The hash of the pool’s operator key.

property drep: DRep

The DRep receiving the delegated voting power.

to_cip116_json(writer)[source]

Serializes this certificate to CIP-116 compliant JSON.

Parameters:: writer (JsonWriter) – The JsonWriter to write the JSON to.
Raises:: CardanoError – If serialization fails.
Return type:: None
