Annotation Type External

@Target(METHOD)
public @interface External

Annotation that can be used to indicate whether the method will be exposed externally.

In order for a method to be called from outside the contract (EOA or another contract), it needs to be annotated as External. The annotated methods will be registered on the exportable API list. Any attempt to call a non-external method from outside the contract will fail.

If the readonly element is specified and its value is true, i.e., @External(readonly=true), the method will have read-only access to the state DB.

NOTE: The special method, named fallback, cannot be annotated with @External. (i.e., fallback method cannot be specified in the transaction message as a callee method, and it can only be called via plain ICX transfer message.)
