Constants

const Version = "0.10.0"

Version specifies the current generator version.

const VersionId = 5

VersionId specifies the current generator version identifier. It is used to validate generated code compatibility and is increased when there are changes in the generated code. Internal generator changes that don't change the output do not cause an increase.

Functions

func Clean

func Clean(codeGenerator CodeGenerator, path string) error

Clean removes generated files in the given path. Removes *.obx.go and objectbox-model.go but keeps objectbox-model.json

func ModelInfoFile

func ModelInfoFile(dir string) string

ModelInfoFile returns the model info JSON file name in the given directory

func Process

func Process(options Options) error

Process is the main API method of the package it takes source file & model-information file paths and generates bindings (as a sibling file to the source file)

func WriteFile

func WriteFile(file string, data []byte, permSource string) error

WriteFile writes data to targetFile, while using permissions either from the targetFile or permSource

Types

type CodeGenerator

type CodeGenerator interface {
	// BindingFiles returns names of binding files for the given entity file.
	BindingFiles(forFile string, options Options) []string

	// ModelFile returns the model GO file for the given JSON info file path
	ModelFile(forFile string, options Options) string

	// IsGeneratedFile returns true if the given path is recognized as a file generated by this generator
	IsGeneratedFile(file string) bool

	// ParseSource reads the source file and creates a model representation
	ParseSource(sourceFile string) (*model.ModelInfo, error)

	// WriteBindingFiles generates and writes binding source code files
	WriteBindingFiles(sourceFile string, options Options, mergedModel *model.ModelInfo) error

	// WriteBindingFiles generates and writes binding source code file for model setup
	WriteModelBindingFile(options Options, mergedModel *model.ModelInfo) error
}

CodeGenerator interface is used to abstract per-language generators, e.g. for Go, C, C++, etc

type Options

type Options struct {
	ModelInfoFile string
	Rand          *rand.Rand
	InPath        string
	OutPath       string

	// NOTE - currently only supports one
	CodeGenerator CodeGenerator
}

Options provide configuration for the generator
