Types

type Block

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

Block represents the information about a basic block to be recorded in the analysis. Note: Our definition of basic block is based on control structures; we don't break apart && and ||. We could but it doesn't seem important enough to bother.

type Buffer

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

A Buffer is a queue of edits to apply to a given byte slice.

func NewBuffer

func NewBuffer(data []byte) *Buffer

NewBuffer returns a new buffer to accumulate changes to an initial data slice. The returned buffer maintains a reference to the data, so the caller must ensure the data is not modified until after the Buffer is done being used.

func (*Buffer) Bytes

func (b *Buffer) Bytes() []byte

Bytes returns a new byte slice containing the original data with the queued edits applied.

func (*Buffer) Delete

func (b *Buffer) Delete(start, end int)

Delete delete

func (*Buffer) Insert

func (b *Buffer) Insert(pos int, new string)

Insert insert

func (*Buffer) Replace

func (b *Buffer) Replace(start, end int, new string)

Replace replace

func (*Buffer) String

func (b *Buffer) String() string

String returns a string containing the original data with the queued edits applied.

type File

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

File is a wrapper for the state of a file used in the parser. The basic parse tree walker is a method of this type.

func (*File) Visit

func (f *File) Visit(node ast.Node) ast.Visitor

Visit implements the ast.Visitor interface.
