type DocumentMapping struct {
	Properties map[string]*DocumentMapping `json:"properties,omitempty"`
	Field      *FieldMapping               `json:"field,omitempty"`
}

func NewDocumentMapping 

func NewDocumentMapping() *DocumentMapping

func ParseSchema 

func ParseSchema(schema []byte) (*DocumentMapping, error)

func (*DocumentMapping) UnmarshalJSON 

func (dm *DocumentMapping) UnmarshalJSON(data []byte) error

type FieldMapping 

type FieldMapping struct {
	Name string
	FieldMappingI
}

func NewFieldMapping 

func NewFieldMapping(name string, i FieldMappingI) *FieldMapping

func (*FieldMapping) UnmarshalJSON 

func (f *FieldMapping) UnmarshalJSON(data []byte) error

type FieldMappingI 

type FieldMappingI interface {
	FieldName() string
	FieldType() pspb.FieldType
	Options() pspb.FieldOption
	Base() *BaseFieldMapping
	IsArray() bool
}

type GeoPointFieldMapping 

type GeoPointFieldMapping struct {
	*BaseFieldMapping
	IgnoreZValue bool   `json:"ignore_z_value,omitempty"`

type IndexMapping 

type IndexMapping struct {
	DocumentMapping *DocumentMapping `json:"doc_mapping"`
	//it is not config in index
	DefaultDateTimeParserName string `json:"-"`
	// contains filtered or unexported fields
}

An IndexMapping controls how objects are placed into an index. First the type of the object is determined. Once the type is know, the appropriate DocumentMapping is selected by the type. If no mapping was determined for that type, a DefaultMapping will be used.

func NewIndexMapping 

func NewIndexMapping() *IndexMapping

NewIndexMapping creates a new IndexMapping that will use all the default indexing rules
