Functions

func ActivateContract

func ActivateContract(tblid int64, prefix string, active bool)

ActivateContract sets Active status of the contract in smartVM

func Compile

func Compile(src, prefix string, active bool, tblid int64) error

Compile compiles contract source code in smartVM

func CompileBlock

func CompileBlock(src, prefix string, active bool, tblid int64) (*script.Block, error)

CompileBlock calls CompileBlock for smartVM

func CompileEval

func CompileEval(src string, prefix uint32) error

CompileEval calls CompileEval for smartVM

func EvalIf

func EvalIf(src, prefix string, extend *map[string]interface{}) (bool, error)

EvalIf calls EvalIf for smartVM

func Extend

func Extend(ext *script.ExtendData)

Extend set extendeds variable and functions in smartVM

func ExtendCost

func ExtendCost(ext func(string) int64)

ExtendCost sets the cost of calling extended obj in smartVM

Float converts int64, string to float64

func FlushBlock

func FlushBlock(root *script.Block)

FlushBlock calls FlushBlock for smartVM

func GetUsedContracts

func GetUsedContracts(name string, state uint32, full bool) []string

GetUsedContracts returns the list of contracts which are called from the specified contract

func Run

func Run(block *script.Block, params []interface{}, extend *map[string]interface{}) (ret []interface{}, err error)

Run executes Block in smartVM

TxJSON returns JSON data which has been generated from Tx data and extended variables

Types

type Contract

type Contract struct {
	Name          string
	Called        uint32
	FreeRequest   bool
	TxPrice       int64   // custom price for citizens
	TxGovAccount  int64   // state wallet
	EGSRate       float64 // money/EGS rate
	TableAccounts string
	StackCont     []string // Stack of called contracts
	Extend        *map[string]interface{}
	Block         *script.Block
}

Contract contains the information about the contract.

func GetContract

func GetContract(name string, state uint32) *Contract

GetContract returns true if the contract exists in smartVM

func GetContractByID

func GetContractByID(id int32) *Contract

GetContractByID returns true if the contract exists

func (*Contract) GetFunc

func (contract *Contract) GetFunc(name string) *script.Block

GetFunc returns the block of the specified function in the contract
