TransactionInputSet

class cometa.transaction_body.transaction_input_set.TransactionInputSet(ptr=None)[source]

Bases: Set[TransactionInput]

Represents an ordered set of transaction inputs.

Transaction inputs are unique references to UTXOs being spent. The set maintains ordering and prevents duplicates.

__init__(ptr=None)[source]

Return type:: None

__enter__()[source]

Return type:: TransactionInputSet

__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 TransactionInputSet from CBOR data.

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

classmethod from_list(inputs)[source]

Creates a TransactionInputSet from an iterable of TransactionInput objects.

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

Example

>>> input1 = TransactionInput.from_hex(tx_hash1, 0)
>>> input2 = TransactionInput.from_hex(tx_hash2, 1)
>>> input_set = TransactionInputSet.from_list([input1, input2])

to_cbor(writer)[source]

Serializes the input set to CBOR format.

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

add(tx_input)[source]

Adds a transaction input to the set.

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

get(index)[source]

Retrieves a transaction input at the specified index.

Parameters:

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

Returns:

The TransactionInput at the specified index.

Raises:

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

Return type:

TransactionInput

property is_tagged: bool

Whether this set uses Conway era tagged encoding.

Returns:: True if using tagged encoding, False otherwise.

__len__()[source]

Returns the number of inputs in the set.

Return type:: int

__iter__()[source]

Iterates over all inputs in the set.

Return type:: Iterator[TransactionInput]

__getitem__(index)[source]

Gets an input by index using bracket notation.

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

__bool__()[source]

Returns True if the set is not empty.

Return type:: bool

to_cip116_json(writer)[source]

Serializes this object to CIP-116 compliant JSON.

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

__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[TransactionInput]) – Another iterable to compare with.
Returns:: True if the sets are disjoint.
Return type:: bool
