Types ¶
type Drain ¶ added in v1.2.0
type Drain struct {
// contains filtered or unexported fields
}
Drain stores errors from Proxy or ProxySet.
func (*Drain) All ¶ added in v1.2.0
All returns all errors which stored. Return nil if no errors stored.
func (*Drain) ArrayArray ¶ added in v1.2.0
ArrayArray returns [][]interface{} value and stores an error.
func (*Drain) CombineErrors ¶ added in v1.2.0
CombineErrors returns an error which combined all stored errors. Return nil if not erros stored.
func (*Drain) First ¶ added in v1.2.0
First returns a stored error. Returns nil if there are no errors.
func (*Drain) Float64Array ¶ added in v1.2.0
Float64Array returns []float64 value and stores an error.
func (*Drain) Int64Array ¶ added in v1.2.0
Int64Array returns []int64 value and stores an error.
func (*Drain) MapArray ¶ added in v1.2.0
MapArray returns []map[string]interface{} value and stores an error.
func (*Drain) ProxyArray ¶ added in v1.2.0
ProxyArray returns []Proxy value and stores an error.
func (*Drain) StringArray ¶ added in v1.2.0
StringArray returns []string value and stores an error.
type Error ¶
type Error interface { // ErrorType returns type of error. ErrorType() ErrorType // FullAddress returns query string where cause first error. FullAddress() string }
Error get detail information of the errror.
type ErrorType ¶
type ErrorType int
ErrorType is type of errors
const ( // Etype means expected type is not matched with actual. Etype ErrorType = iota + 1 // Enotfound means key or index doesn't exist. Enotfound // EmapNorArray means target is not a map nor an array (for JSON Pointer) EmapNorArray // EconvertFailure means value conversion is failed. EconvertFailure // EinvalidIndex means token is invalid as index (for JSON Pointer) EinvalidIndex // EinvalidQuery means query is invalid as JSON Pointer. EinvalidQuery // ErequiredType means the type mismatch against user required one. // For example M() requires map, A() requires array. ErequiredType )
type Proxy ¶
type Proxy interface { // Nil returns true, if target value is nil. Nil() bool // Value returns a proxied value. If there are no values, it returns // error. Value() (interface{}, error) // Bool returns its value. If value isn't the type, it returns error. Bool() (bool, error) // Int64 returns its value. If value isn't the type, it returns error. Int64() (int64, error) // Float64 returns its value. If value isn't the type, it returns error. Float64() (float64, error) // String returns its value. If value isn't the type, it returns error. String() (string, error) // Array returns its value. If value isn't the type, it returns error. Array() ([]interface{}, error) // Map returns its value. If value isn't the type, it returns error. Map() (map[string]interface{}, error) // A returns an item from value treated as the array. A(n int) Proxy // M returns an item from value treated as the map. M(k string) Proxy // P returns which pointed by JSON Pointer's query q. P(q string) Proxy // ProxySet returns a set which converted from its array value. ProxySet() ProxySet // Q returns set of all items which property matchs with k. Q(k string) ProxySet // contains filtered or unexported methods }
Proxy is a proxy to access a document (interface{}).
type ProxySet ¶ added in v1.2.0
type ProxySet interface { // Empty returns true when the set is empty. Empty() bool // Len returns count of items in the set. Len() int // BoolArray returns []bool which converterd from the set. BoolArray() ([]bool, error) // Int64Array returns []int64 which converterd from the set. Int64Array() ([]int64, error) // Float64Array returns []float64 which converterd from the set. Float64Array() ([]float64, error) // StringArray returns []string which converterd from the set. StringArray() ([]string, error) // ArrayArray returns [][]interface{} which converterd from the set. ArrayArray() ([][]interface{}, error) // MapArray returns []map[string]interface{} which converterd from the set. MapArray() ([]map[string]interface{}, error) // ProxyArray returns []Proxy which wrap each items. ProxyArray() ([]Proxy, error) // A returns an proxy for index in the set. A(n int) Proxy // Q returns set of all items which property matchs with k. Q(k string) ProxySet // Qc returns set of property of all items. Qc(k string) ProxySet // contains filtered or unexported methods }
ProxySet proxies to access to set.
type Type ¶
type Type int
Type is type of value.
const ( // Tunknown shows value is not supported. Tunknown Type = iota // Tnil shows value is nil. Tnil // Tbool shows value is bool. Tbool // Tint64 shows value is int64. Tint64 // Tfloat64 shows value is float64. Tfloat64 // Tstring shows value is string. Tstring // Tarray shows value is an array ([]interface{}) Tarray // Tmap shows value is a map (map[string]interface{}) Tmap )
