Class HookCall

java.lang.Object
com.hedera.hashgraph.sdk.HookCall
Direct Known Subclasses:
FungibleHookCall, NftHookCall
public abstract class HookCall extends Object
Specifies a call to a hook from within a transaction.

Often the hook's entity is implied by the nature of the call site. For example, when using an account allowance hook inside a crypto transfer, the hook's entity is necessarily the account whose authorization is required.

For future extension points where the hook owner is not forced by the context, we include the option to fully specify the hook id for the call.
