}

Tokenizer is the struct used to generate SQL tokens for the parser.

func NewStringTokenizer 

func NewStringTokenizer(sql string) *Tokenizer

NewStringTokenizer creates a new Tokenizer for the sql string.

func (*Tokenizer) Error 

func (tkn *Tokenizer) Error(err string)

Error is called by go yacc if there's a parsing error.

func (*Tokenizer) Lex 

func (tkn *Tokenizer) Lex(lval *yySymType) int

Lex returns the next token form the Tokenizer. This function is used by go yacc.

func (*Tokenizer) Scan 

func (tkn *Tokenizer) Scan() (int, []byte)

Scan scans the tokenizer for the next token and returns the token type and an optional value.

type TrackedBuffer 

type TrackedBuffer struct {
	*bytes.Buffer
	// contains filtered or unexported fields
}

TrackedBuffer is used to rebuild a query from the ast. bindLocations keeps track of locations in the buffer that use bind variables for efficient future substitutions. nodeFormatter is the formatting function the buffer will use to format a node. By default(nil), it's FormatNode. But you can supply a different formatting function if you want to generate a query that's different from the default.

func NewTrackedBuffer 

func NewTrackedBuffer(nodeFormatter func(buf *TrackedBuffer, node AdmNode)) *TrackedBuffer

NewTrackedBuffer creates a new TrackedBuffer.

func (*TrackedBuffer) Myprintf 

func (buf *TrackedBuffer) Myprintf(format string, values ...interface{})

Myprintf mimics fmt.Fprintf(buf, ...), but limited to Node(%v), Node.Value(%s) and string(%s). It also allows a %a for a value argument, in which case it adds tracking info for future substitutions.

The name must be something other than the usual Printf() to avoid "go vet" warnings due to our custom format specifiers.
