Types

type NodeApiResolver

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

NodeApiResolver can resolve API requests

func NewNodeApiResolver

func NewNodeApiResolver(scDataGetter ScDataGetter, statusMetricsHandler StatusMetricsHandler) (*NodeApiResolver, error)

NewNodeApiResolver creates a new NodeApiResolver instance

func (*NodeApiResolver) GetVmValue

func (nar *NodeApiResolver) GetVmValue(address string, funcName string, argsBuff ...[]byte) ([]byte, error)

GetVmValue retrieves data stored in a SC account through a VM

func (*NodeApiResolver) IsInterfaceNil

func (nar *NodeApiResolver) IsInterfaceNil() bool

IsInterfaceNil returns true if there is no value under the interface

func (*NodeApiResolver) StatusMetrics

func (nar *NodeApiResolver) StatusMetrics() StatusMetricsHandler

StatusMetrics returns an implementation of the StatusMetricsHandler interface

type ScDataGetter

type ScDataGetter interface {
	Get(scAddress []byte, funcName string, args ...[]byte) ([]byte, error)
	IsInterfaceNil() bool
}

ScDataGetter defines how data should be get from a SC account

type StatusMetricsHandler

type StatusMetricsHandler interface {
	StatusMetricsMap() (map[string]interface{}, error)
	IsInterfaceNil() bool
}

StatusMetricsHandler is the interface that defines what a node details handler/provider should do
