Schema represents a JSON Schema compatible CNAB Definition

func (*Schema) CoerceValue

func (s *Schema) CoerceValue(value interface{}) interface{}

CoerceValue can be used to turn float and other numeric types into integers. When unmarshaled, often integer values are not represented as an integer. This is a convenience method.

func (*Schema) ConvertValue

func (s *Schema) ConvertValue(val string) (interface{}, error)

ConvertValue attempts to convert the given string value to the type from the definition. Note: this is only applicable to string, number, integer and boolean types

func (*Schema) GetType

func (s *Schema) GetType() (string, bool, error)

GetType will return the singular type for a given schema and a success boolean. If the schema does not have a single type, it will return the false boolean and an error.

func (*Schema) GetTypes

func (s *Schema) GetTypes() ([]string, bool, error)

GetTypes will return the types (as a slice) for a given schema and a success boolean. If the schema has a single type, it will return the false boolean and an error.

func (*Schema) UnmarshalJSON

func (s *Schema) UnmarshalJSON(data []byte) error

UnmarshalJSON provides an implementation of a JSON unmarshaler that uses the github.com/qri-io/jsonschema to load and validate a given schema. If it is valid, then the json is unmarshaled.

func (*Schema) Validate

func (s *Schema) Validate(data interface{}) ([]ValidationError, error)

Validate applies JSON Schema validation to the data passed as a parameter. If validation errors occur, they will be returned in as a slice of ValidationError structs. If any other error occurs, it will be returned as a separate error

type ValidationError

type ValidationError struct {
	Path  string
	Error string
}

ValidationError error represents a validation error against the JSON Schema. The type includes the path in the given object and the error message
