PlutusV2ScriptSet

class cometa.witness_set.plutus_v2_script_set.PlutusV2ScriptSet(ptr=None)[source]

Bases: Set[PlutusV2Script]

Represents a set of Plutus V2 scripts.

Plutus V2 scripts are smart contracts introduced in the Vasil hard fork. V2 scripts have access to reference inputs, inline datums, and reference scripts, making them more efficient than V1 scripts.

__init__(ptr=None)[source]

Initializes a new PlutusV2ScriptSet.

Parameters:: ptr – Optional FFI pointer to an existing script set. If None, creates a new set.
Raises:: CardanoError – If creation fails or if ptr is NULL.
Return type:: None

__enter__()[source]

Return type:: PlutusV2ScriptSet

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

Return type:: None

__repr__()[source]

Return repr(self).

Return type:: str

classmethod from_cbor(reader)[source]

Deserializes a PlutusV2ScriptSet from CBOR data.

Parameters:: reader (CborReader) – A CborReader positioned at the script set data.
Returns:: A new PlutusV2ScriptSet deserialized from the CBOR data.
Raises:: CardanoError – If deserialization fails.
Return type:: PlutusV2ScriptSet

classmethod from_list(scripts)[source]

Creates a PlutusV2ScriptSet from an iterable of PlutusV2Script objects.

Parameters:: scripts (Iterable[PlutusV2Script]) – An iterable of PlutusV2Script objects.
Returns:: A new PlutusV2ScriptSet containing all the scripts.
Raises:: CardanoError – If creation fails.
Return type:: PlutusV2ScriptSet

to_cbor(writer)[source]

Serializes the script set to CBOR format.

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

property use_tag: bool

Whether the set uses Conway era tagged encoding.

Returns:: True if using tagged encoding, False for legacy array encoding.

add(script)[source]

Adds a Plutus V2 script to the set.

Parameters:: script (PlutusV2Script) – The PlutusV2Script to add.
Raises:: CardanoError – If addition fails.
Return type:: None

get(index)[source]

Retrieves a Plutus V2 script at the specified index.

Parameters:

index (int) – The index of the script to retrieve.

Returns:

The PlutusV2Script at the specified index.

Raises:

CardanoError – If retrieval fails.
IndexError – If index is out of bounds.

Return type:

PlutusV2Script

__len__()[source]

Returns the number of scripts in the set.

Return type:: int

__iter__()[source]

Iterates over all scripts in the set.

Return type:: Iterator[PlutusV2Script]

__getitem__(index)[source]

Gets a script by index using bracket notation.

Parameters:: index (int)
Return type:: PlutusV2Script

__bool__()[source]

Returns True if the set is not empty.

Return type:: bool

__contains__(item)[source]

Checks if an item is in the set.

Parameters:: item (object)
Return type:: bool

isdisjoint(other)[source]

Returns True if the set has no elements in common with other.

Parameters:: other (Iterable[PlutusV2Script]) – Another iterable to compare with.
Returns:: True if the sets are disjoint.
Return type:: bool
