TranslateMappings translates dot notation mappings

func TranslateMappingsToTree

func TranslateMappingsToTree(scope data.Scope, mappings []*Expr, tree map[string]interface{}, log logger.Logger) (err error)

TranslateMappingsToTree translates dot notation mappings

Types

type Adapter

type Adapter struct {
	Handler api.ServiceFunc
}

Adapter is an adapter activity for ServiceFunc

func (*Adapter) Eval

func (a *Adapter) Eval(ctx activity.Context) (done bool, err error)

Eval evaluates the adapter activity

func (*Adapter) Metadata

func (a *Adapter) Metadata() *activity.Metadata

Metadata returns the metadata for the adapter activity

type Expr

type Expr struct {
	expression.Expr
	Name string
	// contains filtered or unexported fields
}

Expr is an expression with its original source

func NewExpr

func NewExpr(name, source string, expr expression.Expr) *Expr

NewExpr creates a new expression

func (*Expr) String

func (e *Expr) String() string

String gets the source of the expression

type Microgateway

type Microgateway struct {
	Name          string
	Async         bool
	Steps         []Step
	Responses     []Response
	Configuration map[string]interface{}
}

Microgateway defines a microgateway

type Output

type Output struct {
	Code  *Expr
	Data  *Expr
	Datum []*Expr
}

Output defines response output values back to a trigger event.

type Response

type Response struct {
	Condition *Expr
	Error     bool
	Output    Output
}

Response defines response handling rules.

type Service

type Service struct {
	Name     string
	Settings []Setting
	Activity activity.Activity
}

Service defines a functional target that may be invoked by a step in an execution flow.

type Setting

type Setting struct {
	Name  string
	Value interface{}
}

Setting is a service setting

type Step

type Step struct {
	Condition     *Expr
	Service       *Service
	Input         []*Expr
	HaltCondition *Expr
}

Step conditionally defines a step in a route's execution flow.
