Functions

func BuildTypeName

func BuildTypeName(t reflect.Type) string

func FormatValue

func FormatValue(value interface{}) string

FormatValue returns a string representing the value

func InvokeMethod

func InvokeMethod(target interface{}, name string, args ...interface{}) ([]reflect.Value, error)

InvokeMethod calls the specified method by reflection

func IsMethodNotFound

func IsMethodNotFound(err error) bool

func IsPrimitiveValue

func IsPrimitiveValue(v reflect.Value) bool

IsPrimitiveValue returns true if passed a value of primitive type: int, bool, etc Note that string (like []byte) is not treated as a primitive type

func JSONMergeStruct

func JSONMergeStruct(dest, src interface{})

JSONMergeStruct merges src into dest It uses a JSON marshal & unmarshal, so only fields that are JSON-visible will be copied

func ReflectRecursive

func ReflectRecursive(v reflect.Value, visitor visitorFunc) error

ReflectRecursive calls visitor with v and every recursive sub-value, skipping subtrees if SkipReflection is returned

func RegisterPrinter

func RegisterPrinter(p Printer)

RegisterPrinter adds a custom printer function

func ValueAsString

func ValueAsString(value reflect.Value) string

ValueAsString returns a human-readable string representation of the passed value

Types

type MethodNotFoundError

type MethodNotFoundError struct {
	Name   string
	Target interface{}
}

func (*MethodNotFoundError) Error

func (e *MethodNotFoundError) Error() string

type Printer

type Printer func(o interface{}) (string, bool)

Printer is a custom printer function, so we can add special display for objects (without introducing a package dependency)
