Web3RequestBuilder.h

class FWeb3BaseRequest

This class is an abstract base class meant to be inherited by different types of external calls and its abstract BuildRequest member function overridden.

Subclassed by FWeb3ExternalRPCRequest, FWeb3RPCRequest, FWeb3SendContractRequest

Public Functions

virtual ~FWeb3BaseRequest() = default

inline void ExecuteRequest(): Makes the external call to HyperPlay’s http server or another rpc provider.

Public Members

int32 ChainID: The chain id to send with the HyperPlay http request, if applicable

FString ChainMetadataVar: The chain metadata so the chain can be added to the users wallet if it is not already added. Only applicable for HyperPlay http request calls.

FHttpRequestCompleteDelegate OnCompleteDelegate: The callback to be called after the http request completes

Protected Types

typedef TJsonWriterFactory<TCHAR, TCondensedJsonPrintPolicy<TCHAR>> FCondensedJsonStringWriterFactory

typedef TJsonWriter<TCHAR, TCondensedJsonPrintPolicy<TCHAR>> FCondensedJsonStringWriter

Protected Functions

void InitializeRequest()

virtual void BuildRequest() = 0: Override BuildRequest function in child class to create custom external http calls

void FinalizeRequest() const

Protected Attributes

FString RequestUrl

TSharedPtr<FJsonObject> RequestObject

TSharedPtr<FJsonObject> ChainObject

FString HttpContentString

FHttpRequestPtr Request

class FWeb3RPCRequest : public FWeb3BaseRequest 

This is a child class of FWeb3BaseRequest that overrides BuildRequest to make calls to the /rpc endpoint of the local HyperPlay http server

Public Members

FString Request: The json rpc request to make, as a string

class FWeb3ExternalRPCRequest : public FWeb3BaseRequest 

This is a child class of FWeb3BaseRequest that overrides BuildRequest to make json-rpc calls to an external rpc provider

Public Members

FString Url: The url of the external rpc provider

FString RequestString: The json rpc request to make, as a string

class FWeb3SendContractRequest : public FWeb3BaseRequest 

Subclassed by FWeb3CallContractRequest

Public Members

FString ContractAddressVar: Contract address

FString FunctionNameVar: Function name to call send on

FString ABIVar: Contract ABI, as a string

FString ValueInWeiVar: Value in wei to send with the request. int64 is not big enough so we store it as FString

TArray<FString> ParamsVar: Array of string params. uint32 and struct params are parsed from their string values on the http server

int32 GasLimitVar: Gas limit for the transaction

class FWeb3CallContractRequest : public FWeb3SendContractRequest : FWeb3CallContractRequest is a child class of FWeb3SendContractRequest that overrides BuildRequest to make calls to the /callContract endpoint of the local HyperPlay http server. It has the same interface as FWeb3SendContractRequest.
