Class EntryFunction

constructor

• new EntryFunction(module_name, function_name, type_args, args): EntryFunction

• Contains the payload to run a function within a module.

  Parameters

  • module_name: ModuleId

    Fully qualified module name in format "account_address::module_name" e.g. "0x1::coin"

  • function_name: Identifier

    The function name. e.g "transfer"

  • type_args: TypeTag[]

    Type arguments that move function requires.

  • args: EntryFunctionArgument[]

    arguments to the move function.

  Returns EntryFunction

  Example

  A coin transfer function has one type argument "CoinType".

  public entry fun transfer<CoinType>(from: &signer, to: address, amount: u64)
  Copy

  Example

  A coin transfer function has three arguments "from", "to" and "amount".

  public entry fun transfer<CoinType>(from: &signer, to: address, amount: u64)
  Copy

Readonly args

Readonly function_name

Readonly module_name

Readonly type_args

serialize

• serialize(serializer): void

• Parameters

  • serializer: Serializer

  Returns void

Static build

• build(module_id, function_name, type_args, args): EntryFunction

• A helper function to build a EntryFunction payload from raw primitive values

  Parameters

  • module_id: `${string}::${string}`

    Fully qualified module name in format "AccountAddress::module_id" e.g. "0x1::coin"

  • function_name: string

    Function name

  • type_args: TypeTag[]

    Type arguments that move function requires.

  • args: EntryFunctionArgument[]

    Arguments to the move function.

  Returns EntryFunction

  EntryFunction

  Example

  A coin transfer function has one type argument "CoinType".

  public(script) fun transfer<CoinType>(from: &signer, to: address, amount: u64,)
  Copy

  Example

  A coin transfer function has three arguments "from", "to" and "amount".

  public(script) fun transfer<CoinType>(from: &signer, to: address, amount: u64,)
  Copy

Static deserialize

• deserialize(deserializer): EntryFunction

• Deserializes an entry function payload with the arguments represented as EntryFunctionBytes instances.

  Parameters

  • deserializer: Deserializer

  Returns EntryFunction

  A deserialized EntryFunction payload for a transaction.

  See

  EntryFunctionBytes

  NOTE: When you deserialize an EntryFunction payload with this method, the entry function arguments are populated into the deserialized instance as type-agnostic, raw fixed bytes in the form of the EntryFunctionBytes class.

  In order to correctly deserialize these arguments as their actual type representations, you must know the types of the arguments beforehand and deserialize them yourself individually.

  One way you could achieve this is by using the ABIs for an entry function and deserializing each argument as its given, corresponding type.
