Types

type Builder

type Builder struct {
	// contains filtered or unexported fields
}

Builder lets you add all the go files in all the packages that you care about, then constructs the type source data.

func New

func New() *Builder

New constructs a new builder.

func (*Builder) AddBuildTags

func (b *Builder) AddBuildTags(tags ...string)

AddBuildTags adds the specified build tags to the parse context.

func (*Builder) AddDir

func (b *Builder) AddDir(dir string) error

AddDir adds an entire directory, scanning it for go files. 'dir' should have a single go package in it. GOPATH, GOROOT, and the location of your go binary (`which go`) will all be searched if dir doesn't literally resolve.

func (*Builder) AddDirRecursive

func (b *Builder) AddDirRecursive(dir string) error

AddDirRecursive is just like AddDir, but it also recursively adds subdirectories; it returns an error only if the path couldn't be resolved; any directories recursed into without go source are ignored.

func (*Builder) AddFile

func (b *Builder) AddFile(pkg string, path string, src []byte) error

AddFile adds a file to the set. The pkg must be of the form "canonical/pkg/path" and the path must be the absolute path to the file.

func (*Builder) FindTypes

func (b *Builder) FindTypes() (types.Universe, error)

FindTypes finalizes the package imports, and searches through all the packages for types.
