Operation class abstract

Base class for all operations in a Stellar transaction.

Operations are the commands that mutate the ledger state. A transaction contains one or more operations that are executed atomically. Each operation can optionally specify a source account that differs from the transaction's source account.

Available operation types:

• CreateAccountOperation - Create and fund a new account
• PaymentOperation - Send assets to an account
• PathPaymentStrictReceiveOperation - Send through a payment path with exact receive amount
• PathPaymentStrictSendOperation - Send through a payment path with exact send amount
• ManageSellOfferOperation - Create, update, or delete a sell offer
• ManageBuyOfferOperation - Create, update, or delete a buy offer
• CreatePassiveSellOfferOperation - Create a passive sell offer
• SetOptionsOperation - Set account options (inflation, thresholds, signers, etc.)
• ChangeTrustOperation - Create, update, or delete a trustline
• AllowTrustOperation - Authorize or deauthorize an account to hold an asset
• AccountMergeOperation - Merge one account into another
• ManageDataOperation - Set, modify, or delete a data entry
• BumpSequenceOperation - Bump account sequence number
• CreateClaimableBalanceOperation - Create a claimable balance entry
• ClaimClaimableBalanceOperation - Claim a claimable balance
• BeginSponsoringFutureReservesOperation - Begin sponsoring reserves for another account
• EndSponsoringFutureReservesOperation - End sponsoring reserves
• RevokeSponsorshipOperation - Revoke sponsorship of a ledger entry or signer
• ClawbackOperation - Clawback an asset from an account
• ClawbackClaimableBalanceOperation - Clawback a claimable balance
• SetTrustLineFlagsOperation - Set flags on a trustline
• LiquidityPoolDepositOperation - Deposit assets into a liquidity pool
• LiquidityPoolWithdrawOperation - Withdraw assets from a liquidity pool
• InvokeHostFunctionOperation - Invoke a Soroban smart contract function
• ExtendFootprintTTLOperation - Extend the TTL of Soroban contract storage entries
• RestoreFootprintOperation - Restore archived Soroban contract storage entries

Example:

// Create a payment operation
var payment = PaymentOperationBuilder(
  destinationAccountId,
  Asset.native(),
  "100.50"
).build();

// Create a payment with custom source account
var paymentWithSource = PaymentOperationBuilder(
  destinationAccountId,
  Asset.native(),
  "100.50"
).setSourceAccount(customSourceAccount).build();

// Add operation to a transaction
var transaction = TransactionBuilder(sourceAccount)
  .addOperation(payment)
  .build();
