public class Obligation<P>
implements Contract

An obligation contract commits the obligor to delivering a specified amount of a fungible asset (for example the class Cash contract) at a specified future point in time. Settlement transactions may split and merge contracts across multiple input and output states. The goal of this design is to handle amounts owed, and these contracts are expected to be netted/merged, with settlement only for any remainder amount.

Method Detail

verify

public void verify(@NotNull
                   LedgerTransaction tx)

Takes an object that represents a state transition, and ensures the inputs/outputs/commands make sense. Must throw an exception if there's a problem that should prevent state transition. Takes a single object rather than an argument so that additional data can be added without breaking binary compatibility with existing contract code.
