Trying Represent Bitcoin Transactions

[leelaba...@ensoftcorp.com]

Hello,

Is there a way to find the amount of bitcoins each TransactionInput sent to the Transaction object? I also want to know if it is possible to find the amount that is sent to the TransactionObject and the address associated with the Transaction Object. 

Thanks

Sounds like TransactionInput.getValue() is your friend. However if the
input isn't connected to an output of a previous transaction then that
value isn't known.

Transactions can send to any number of addresses (and other script
types) at the same time. Loop through all the outputs and use the
getAddressFrom* methods.

Thanks for the reply. I think that is the right thing to due. However when I try it out on the first 5000 blocks of the block chain (from the genesis block) all of the Transactioninputs have a null value for the .getValue() because none of them are "connected" to an TransactionOutput. Is this a limitation of bitcoinJ? Do TransactionsInputs only have values if they come from a wallet application that is running? I am more interested in this for research purposes.

Thanks.

The Wallet class keeps only transactions that are relevant to the
wallet. This means that the inputs of incoming transactions are
typically not connected and this the input value isn't known.

Do you know if there is a way to get the hash of the transaction from where the transaction input from for a particular transaction. I don't mean the transaction hash of the transaction where you get the list of transaction inputs of a particular TransactionInput object but the hash of the Transaction from where the Transaction Output that corresponds to the given TransActionInput.

Thanks. I hope that makes sense.
