Functions

func CheckFileExist

func CheckFileExist(fileName string) bool

CheckFileExist check if given file exists or not

func IntegerValidator

func IntegerValidator(ans interface{}) error

IntegerValidator validates that the provided object can be properly converted to an int value

func IsValid

func IsValid(value string, validValues []string) bool

func IsValidDir

func IsValidDir(fileName string) bool

func NameValidator

func NameValidator(name interface{}) error

NameValidator provides a Validator view of the ValidateName function.

func NilValidator

func NilValidator(interface{}) error

NilValidator always validates

func ValidateName

func ValidateName(name string) error

ValidateName will do validation of application & component names according to DNS (RFC 1123) rules Criteria for valid name in kubernetes: https://github.com/kubernetes/community/blob/master/contributors/design-proposals/architecture/identifiers.md

Types

type EnumValue

type EnumValue struct {
	Provided string
	Value    interface{}
	// contains filtered or unexported fields
}

func NewEnumValue

func NewEnumValue(valueName string, values ...interface{}) EnumValue

func (EnumValue) Contains

func (e EnumValue) Contains(ans interface{}) error

func (*EnumValue) Get

func (e *EnumValue) Get() interface{}

func (*EnumValue) GetKnownValues

func (e *EnumValue) GetKnownValues() string

func (EnumValue) IsProvidedValid

func (e EnumValue) IsProvidedValid() bool

func (*EnumValue) MustSet

func (e *EnumValue) MustSet(value interface{})

func (*EnumValue) Set

func (e *EnumValue) Set(value interface{}) error

func (EnumValue) String

func (e EnumValue) String() string

type Validatable

type Validatable struct {
	// Required indicates whether this Validatable is a required value in the context it's supposed to be used
	Required bool `json:"required,omitempty"`
	// Type specifies the type of values this Validatable accepts so that some validation can be performed based on it
	Type string `json:"type"`
	// AdditionalValidators allows users to specify validators (in addition to default ones) to validate this Validatable's value
	AdditionalValidators []Validator `json:"-"`
}

Validatable represents a common ancestor for validatable parameters

func (Validatable) AsValidatable

func (v Validatable) AsValidatable() Validatable

AsValidatable allows avoiding type casts in client code

type Validator

type Validator func(interface{}) error

Validator is a function that validates that the provided interface conforms to expectations or return an error

func GetValidatorFor

func GetValidatorFor(prop Validatable) Validator

GetValidatorFor retrieves a validator for the specified validatable, first validating its required state, then its value based on type then any additional validators in the order specified by Validatable.AdditionalValidators
