Types ¶

type VMContext ¶

type VMContext struct {
	// contains filtered or unexported fields
}

VMContext represents state of the chain during one run of the VM while processing a batch of requests. VMContext object mutates with each request in the bathc. The VMContext is created from immutable vm.VMTask object and UTXO state of the chain address contained in the statetxbuilder.Builder

func NewVMContext ¶

func NewVMContext(task *vm.VMTask, txb *statetxbuilder.Builder) (*VMContext, error)

NewVMContext a constructor

func (*VMContext) Call ¶

func (vmctx *VMContext) Call(targetContract coretypes.Hname, epCode coretypes.Hname, params dict.Dict, transfer coretypes.ColoredBalances) (dict.Dict, error)

Call
