Post-processor

A post-processor registered in ConfigurableCorePool works as an interceptor to execute callback function after executing an interaction. You can customize your handler function with ConfigurableCorePool(pool state after the interaction) and TransitionView exposed by the post-processor.

Take for example, when locating errors, you can check the state after executing an interaction from a large number of events, take the snapshot, think about what happened exactly and resume from that state later.

You can set a post-processor after every interaction in this way.

configurableCorePool.updatePostProcessor(
  (pool: ConfigurableCorePool, transition: TransitionView) => {
    console.log(pool.getPoolState().id);
    console.log(transition.getRecord().id);
    return Promise.resolve();
  }
);

Or set it with a specific interaction.

await configurableCorePool.mint(
  "0x01",
  -887272,
  887272,
  JSBI.BigInt("10860507277202"),
  (pool: ConfigurableCorePool, transition: TransitionView) => {
    console.log(pool.getPoolState().id);
    console.log(transition.getRecord().id);
    return Promise.resolve();
  }
);

Note: If any error happens during the interaction or the post process, the ConfigurableCorePool will recover as the state before that interaction happened, just like contract transaction reverts.
