Escape escapes all values that are not allowed to be stored directly into the cosmos-db.

func NewEdgeG 

func NewEdgeG(g interfaces.Graph) interfaces.Edge

func NewEdgeV 

func NewEdgeV(v interfaces.Vertex) interfaces.Edge

func NewGraph 

func NewGraph(name string) interfaces.Graph

NewGraph creates a new graph query with the given name Hint: The actual graph has to exist on the server in order to execute the query that will be generated with this query builder

func NewPropertyV 

func NewPropertyV(v interfaces.Vertex) interfaces.Property

func NewSimpleQB 

func NewSimpleQB(format string, a ...interface{}) interfaces.QueryBuilder

func NewVertexE

func NewVertexG 

func NewVertexG(g interfaces.Graph) interfaces.Vertex

func SetQueryLanguageTo 

func SetQueryLanguageTo(ql QueryLanguage)

SetQueryLanguageTo sets the query language that shall be used. Per default QueryLanguageCosmosDB is in use.

func ShouldEscape 

func ShouldEscape(value string) bool

ShouldEscape returns true in case the given string needs to be escaped.

func ShouldUnescape 

func ShouldUnescape(value string) bool

ShouldUnescape returns true in case the given string needs to be unescaped.

func ToValueMap 

func ToValueMap(input []byte) (map[string]TypedValue, error)

ToValueMap converts the given input byte array into a map of TypedValue's. The method will fail in case the data in the given byte array does not consist of key value pairs where these values are primitive types.

func UnEscape 

func UnEscape(value string) string

UnEscape reverses potentially applied escaping. In case of an error the original input value will be returned

Types

type Edge 

type Edge struct {
	ID        string `mapstructure:"id"`
	Label     string `mapstructure:"label"`
	Type      Type   `mapstructure:"type"`
	InVLabel  string `mapstructure:"inVLabel"`
	InV       string `mapstructure:"inV"`
	OutVLabel string `mapstructure:"outVLabel"`
	OutV      string `mapstructure:"outV"`
}

Edge represents the cosmos DB type for an edge. As it would be returned by a call to g.E().

func ToEdges 

func ToEdges(input []byte) ([]Edge, error)

ToEdges converts the given input byte array into an array of Edge type. The method will fail in case the data in the given byte array does not contain values of type edge.

func (Edge) String 

func (e Edge) String() string

type Property 

type Property struct {
	ID    string     `mapstructure:"id"`
	Value TypedValue `mapstructure:"value,squash"`
	Label string     `mapstructure:"label"`
}

Property represents the cosmos db type for a property. As it would be returned by a call to .properties().

func ToProperties 

func ToProperties(input []byte) ([]Property, error)

ToProperties converts the given input byte array into an array of Property type. The method will fail in case the data in the given byte array does not contain values of type property.

type QueryLanguage 

type QueryLanguage string
const (
	QueryLanguageCosmosDB         QueryLanguage = "cosmos"
	QueryLanguageTinkerpopGremlin QueryLanguage = "tinkerpop"
)

type ResponseArray 

type ResponseArray []interfaces.Response

ResponseArray an array type for responses

func (ResponseArray) ToEdges

ToEdges converts the given ResponseArray into an array of Edge type. The method will fail in case the data in the given ResponseArray does not contain values of type edge.

func (ResponseArray) ToProperties 

func (responses ResponseArray) ToProperties() ([]Property, error)

ToProperties converts the given ResponseArray into an array of Property type. The method will fail in case the data in the given ResponseArray does not contain values of type property.

func (ResponseArray) ToValues 

func (responses ResponseArray) ToValues() ([]TypedValue, error)

ToValues converts the given ResponseArray into an array of TypedValue type. The method will fail in case the data in the given ResponseArray does not contain primitive values.

func (ResponseArray) ToVertices 

func (responses ResponseArray) ToVertices() ([]Vertex, error)

ToVertices converts the given ResponseArray into an array of Vertex type. The method will fail in case the data in the given ResponseArray does not contain values of type vertex.

type Type 

type Type string

Type defines the cosmos db complex types 

const (
	TypeVertex Type = "vertex"
	TypeEdge   Type = "edge"
)

type TypedValue 

type TypedValue struct {
	Value interface{}
}

TypedValue represents the cosmos DB type for a value in case it is not used/ attached to a complex type.

func ToValues 

func ToValues(input []byte) ([]TypedValue, error)

ToValues converts the given input byte array into an array of TypedValue type. The method will fail in case the data in the given byte array does not contain primitive values.

func (TypedValue) AsBool 

func (tv TypedValue) AsBool() bool

func (TypedValue) AsBoolE 

func (tv TypedValue) AsBoolE() (bool, error)

func (TypedValue) AsFloat64 

func (tv TypedValue) AsFloat64() float64

func (TypedValue) AsFloat64E 

func (tv TypedValue) AsFloat64E() (float64, error)

func (TypedValue) AsInt32 

func (tv TypedValue) AsInt32() int32
