Added

• add to_json() to the generated model classes to get a JSON-safe representation of the model.
• add extract_signing_payload() to facade to get signing payload which allows signing by hardware keys.
• add cosign_transaction_hash() to facade and account to allow cosigning of transaction hash.

Changed

Fixed

• (NEM) add non-verifiable cosignature transaction to allow signing of the cosignature transaction.

Added

• generate sphinx documentation to provide class-level documentation for SDK
• add useful functions from the SDK V2 that are missing
  • create address alias from namespace id
  • extract namespace ID from address alias
  • create address from decoded address hex string (REST format)
• add metadata_generate_key() since there is no built-in way to convert a string to a metadata key.
• add SymbolAccount class
  • add sign_transaction() to the SymbolAccount to match facade functionality
  • add cosign_transaction() to the SymbolAccount to match facade functionality
  • to improve discoverability, add a helper function(message_encoder) to SymbolAccount, which creates a MessageEncoder used to encrypt/encode messages
• add SymbolPublicAccount class
  • add properties for address and publicKey for better discoverability
• add NemAccount class
  • add sign_transaction() to the NemAccount to match facade functionality
  • to improve discoverability, add a helper function(message_encoder) to NemAccount, which creates a MessageEncoder used to encrypt/encode messages
• add NemPublicAccount class
  • add properties for address and publicKey for better discoverability
• add a create_public_account() and create_account() to the facade for both NEM and Symbol
• add deserialize() function to TransactionFactory in SDK for better discoverability

Added

• generate basic TS-style documentation using typedoc to provide class-level documentation for SDK
• add useful functions from the SDK V2 that are missing
  • create address alias from namespace id
  • extract namespaceID from address alias
  • create address from decoded address hex string (REST format)
• add metadataGenerateKey() since there is no built-in way to convert a string to a metadata key.
• add SymbolAccount class
  • add signTransaction() to the SymbolAccount to match facade functionality
  • add cosignTransaction() to the SymbolAccount to match facade functionality
  • to improve discoverability, add a helper function to SymbolAccount, which creates a MessageEncoder used to encrypt/encode messages

• add NemPublicAccount class
  • add properties for address and publicKey for better discoverability
• add a createPublicAccount() and createAccount() to the facade for both NEM and Symbol
• add deserialize() function to TransactionFactory in SDK for better discoverability

Changed

• improve typescript support by generating type-annotated descriptors that accept strongly typed arguments
• calculating fee for aggregate transaction is not easy to configure via createTransactionFromTypedDescriptor. Add cosignatureCount optional parameter to SymbolFacade createTransactionFromTypedDescriptor

Fixed

• NetworkTimestamp.timestamp is BigInt but models.Timestamp (NEM) is a Number that leads to a mismatch during creation. Add logic to BaseValue to automatically coerce input of Number|BigInt to the desired underlying type when possible.
