transaction-converter.asTransactionTrytes(transactions)

Summary: Converts one or more transaction objects into transaction trytes.
Throws:

• errors.INVALID_TRYTES : Make sure that the object fields in the transactions argument contains valid trytes (A-Z or 9).

Param	Type	Description
transactions	Transaction | Array.<Transaction>	Transaction objects

This method takes one or more transaction objects and converts them into trytes.

Related methods

To get JSON data from the signatureMessageFragment field of the transaction trytes, use the extractJSON() method.

Returns: Trytes | Array.<Trytes> - Transaction trytes
Example

let trytes = TransactionConverter.asTransactionTrytes(transactionObject);

transaction-converter.asTransactionObject(transaction)

Summary: Converts transaction trytes into a transaction object.
Throws:

• errors.INVALID_TRYTES : Make sure that the object fields in the transaction argument contains valid trytes (A-Z or 9).

Param	Type	Description
transaction	Trytes	Transaction trytes

This method takes 2,673 transaction trytes and converts them into a transaction object.

Related methods

To convert more than one transaction into an object at once, use the asTransactionObjects() method.

To get a transaction's trytes from the Tangle, use the getTrytes() method.

Returns: Transaction - transactionObject - A transaction object
Example

let transactionObject = TransactionConverter.asTransactionObject(transactionTrytes);

transaction-converter.asTransactionObjects([hashes])

Summary: Converts one or more transaction trytes into transaction objects.
Throws:

• errors.INVALID_TRYTES : Make sure that transcactions contains valid trytes (A-Z or 9).

Param	Type	Description
[hashes]	Array.<Hash>	Transaction hashes

This method takes an array of transaction hashes and returns a mapper.

If any hashes are given, the mapper function maps them to their converted objects. Otherwise, all hashes are recalculated.

Related methods

To get a transaction's trytes from the Tangle, use the getTrytes() method.

Returns: function - transactionObjectsMapper()
Example

let transactionObjectsMapper = TransactionConverter.asTransactionObjects([hashes]);

transaction-converter~transactionObjectsMapper(trytes)

Param	Type	Description
trytes	Array.<Trytes>	List of transaction trytes to convert

Maps the list of given hashes to a list of converted transaction objects.

Returns: Array.<Transaction> - List of transaction objects with hashes
