All Implemented Interfaces:

public enum SCValType extends Enum<SCValType>
SCValType's original definition in the XDR file is: 
 enum SCValType

     SCV_BOOL = 0,
     SCV_VOID = 1,
     SCV_ERROR = 2,

     // 32 bits is the smallest type in WASM or XDR; no need for u8/u16.
     SCV_U32 = 3,
     SCV_I32 = 4,

     // 64 bits is naturally supported by both WASM and XDR also.
     SCV_U64 = 5,
     SCV_I64 = 6,

     // Time-related u64 subtypes with their own functions and formatting.
     SCV_TIMEPOINT = 7,
     SCV_DURATION = 8,

     // 128 bits is naturally supported by Rust and we use it for Soroban
     // fixed-point arithmetic prices / balances / similar "quantities". These
     // are represented in XDR as a pair of 2 u64s.
     SCV_U128 = 9,
     SCV_I128 = 10,

     // 256 bits is the size of sha256 output, ed25519 keys, and the EVM machine
     // word, so for interop use we include this even though it requires a small
     // amount of Rust guest and/or host library code.
     SCV_U256 = 11,
     SCV_I256 = 12,

     // Bytes come in 3 flavors, 2 of which have meaningfully different
     // formatting and validity-checking / domain-restriction.
     SCV_BYTES = 13,
     SCV_STRING = 14,
     SCV_SYMBOL = 15,

     // Vecs and maps are just polymorphic containers of other ScVals.
     SCV_VEC = 16,
     SCV_MAP = 17,

     // Address is the universal identifier for contracts and classic
     // accounts.
     SCV_ADDRESS = 18,

     // The following are the internal SCVal variants that are not
     // exposed to the contracts.
     SCV_CONTRACT_INSTANCE = 19,

     // SCV_LEDGER_KEY_CONTRACT_INSTANCE and SCV_LEDGER_KEY_NONCE are unique
     // symbolic SCVals used as the key for ledger entries for a contract's
     // instance and an address' nonce, respectively.

  • Method Details

    • values

      public static SCValType[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static SCValType valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
