Simulate
Result data from transaction simulation.
Contains all the data returned by the Soroban RPC simulation, including:
Authorization entries that need signing
Transaction resource data (footprint, resource limits)
The return value from the contract function
This is useful for:
Inspecting which accounts need to sign auth entries
Understanding resource consumption
Examining the simulated return value before submitting
Example:
val simData = tx.getSimulationData()
println("Auth entries: ${simData.auth?.size}")
println("Read footprint: ${simData.transactionData.resources.footprint.readOnly.size}")
println("Return value: ${simData.returnedValue}")Constructors
Properties
Authorization entries returned from simulation. Null if the contract function doesn't require authorization.
The return value from the simulated contract function call. This is the result you would get if the transaction were executed.
Transaction resource data including footprint and resource limits. This must be included in the transaction for execution.
