Golang NewValidator Examples

Example #1

File: writers.go Project: smessier/goa

// NewMediaTypesWriter returns a contexts code writer.
// Media types contain the data used to render response bodies.
func NewMediaTypesWriter(filename string) (*MediaTypesWriter, error) {
	file, err := codegen.SourceFileFor(filename)
	if err != nil {
		return nil, err
	}
	return &MediaTypesWriter{SourceFile: file, Validator: codegen.NewValidator()}, nil
}

Example #2

File: writers.go Project: smessier/goa

// NewUserTypesWriter returns a contexts code writer.
// User types contain custom data structured defined in the DSL with "Type".
func NewUserTypesWriter(filename string) (*UserTypesWriter, error) {
	file, err := codegen.SourceFileFor(filename)
	if err != nil {
		return nil, err
	}
	return &UserTypesWriter{
		SourceFile: file,
		Finalizer:  codegen.NewFinalizer(),
		Validator:  codegen.NewValidator(),
	}, nil
}

Example #3
