Error concatenates all errors into a single string.

func (*Errors) Len

func (e *Errors) Len() int

Len returns the number of errors.

type Properties

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

Properties manages dynamic properties and refreshable objects.

func New

func New() *Properties

New creates and returns a new Properties instance.

func (*Properties) Data

Data returns the current properties.

func (*Properties) ObjectsCount

func (p *Properties) ObjectsCount() int

ObjectsCount returns the number of registered refreshable objects.

Refresh updates the properties and refreshes all bound objects as necessary.

func (*Properties) RefreshBean

func (p *Properties) RefreshBean(v gs.Refreshable, param conf.BindParam, watch bool) error

RefreshBean refreshes a single refreshable object. Optionally registers the object as refreshable if watch is true.

func (*Properties) RefreshField

func (p *Properties) RefreshField(v reflect.Value, param conf.BindParam, watch bool) error

RefreshField refreshes a field of a bean, optionally registering it as refreshable.

type Value

type Value[T interface{}] struct {

}

Value represents a thread-safe object that can dynamically refresh its value.

func (*Value[T]) MarshalJSON

func (r *Value[T]) MarshalJSON() ([]byte, error)

MarshalJSON serializes the stored value as JSON.

func (*Value[T]) OnRefresh

func (r *Value[T]) OnRefresh(prop gs.Properties, param conf.BindParam) error

OnRefresh refreshes the value of the object by binding new properties.
