Types

type ApiError 

type ApiError struct {
	// ID is a unique identifier for this particular occurrence of a problem.
	ID string `json:"id,omitempty"`

	// Title is a short, human-readable summary of the problem that SHOULD NOT change from occurrence to occurrence of the problem, except for purposes of localization.
	Title string `json:"title,omitempty"`

	// Detail is a human-readable explanation specific to this occurrence of the problem. Like title, this field’s value can be localized.
	Detail string `json:"detail,omitempty"`

	// Status is the HTTP status code applicable to this problem, expressed as a string value.
	Status string `json:"status,omitempty"`

	// Code is an application-specific error code, expressed as a string value.
	Code string `json:"code,omitempty"`

	// Meta is an object containing non-standard meta-information about the error.
	Meta *map[string]interface{} `json:"meta,omitempty"`

	// Err is a non published message container for loggin purpose
	Err error `json:"-"`
	// contains filtered or unexported fields
}

ApiError is an struct representing a JSON API error

func ErrTooManyNestedRelationships 

func ErrTooManyNestedRelationships(relationship string) *ApiError

func (*ApiError) AddMeta 

func (e *ApiError) AddMeta(key string, value interface{})

AddMeta adds the meta data for given error. Checks if an object has inited meta field.

func (ApiError) Copy 

func (e ApiError) Copy() *ApiError

Copy returns the new object that is a copy of given error object.

func (*ApiError) Error 

func (e *ApiError) Error() string

ApiError implements the `ApiError` interface.

func (*ApiError) IntStatus 

func (e *ApiError) IntStatus() int

IntStatus returns integer status of the error

func (*ApiError) WithDetail 

func (e *ApiError) WithDetail(detail string) *ApiError

WithDetail sets the detail for given error and then returns the error.

func (*ApiError) WithStatus 

func (e *ApiError) WithStatus(status int) *ApiError

WithStatus sets the ApiError status

type ErrorMapper 

type ErrorMapper struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

ErrorMapper defines the database unidb.Error one-to-one mapping into neuron APIError. The default error mapping is defined in package variable 'DefaultErrorMap'.

func NewDBMapper 

func NewDBMapper() *ErrorMapper

NewDBMapper creates new error handler with already inited ErrorMap

func (*ErrorMapper) Handle 

func (r *ErrorMapper) Handle(dberr *unidb.Error) (*ApiError, error)

Handle enables unidb.Error handling so that proper ErrorObject is returned. It returns ErrorObject if given database error exists in the private error mapping. If provided dberror doesn't have prototype or no mapping exists for given unidb.Error an application 'error' would be returned. Thread safety by using RWMutex.RLock

func (*ErrorMapper) LoadCustomErrorMap 

func (r *ErrorMapper) LoadCustomErrorMap(errorMap map[unidb.Error]ApiError)

LoadCustomErrorMap enables replacement of the ErrorMapper default error map. This operation is thread safe - with RWMutex.Lock

func (*ErrorMapper) UpdateErrorEntry 

func (r *ErrorMapper) UpdateErrorEntry(
	dberr unidb.Error,
	apierr ApiError,
)

UpdateErrorEntry changes single entry in the Error Handler error map. This operation is thread safe - with RWMutex.Lock

type MultipleErrors 

type MultipleErrors []*ApiError

MultipleErrors is the wrapper over error slice implement error interface

func (MultipleErrors) Error 

func (m MultipleErrors) Error() string

Error implements error interface
