package jlexer

import "github.com/mailru/easyjson/jlexer"

Package jlexer contains a JSON lexer implementation.

It is expected that it is mostly used with generated parser code, so the interface is tuned for a parser that knows what kind of data is expected.

type Lexer Uses

❖
type Lexer struct {
    Data []byte // Input data given to the lexer.

    UseMultipleErrors bool // If we want to use multiple errors.
    // contains filtered or unexported fields
}

Lexer is a JSON lexer: it iterates over JSON tokens in a byte slice.

❖
func (r *Lexer) Bytes() []byte

Bytes reads a string literal and base64 decodes it into a byte slice.

func (*Lexer) Consumed Uses

❖
func (r *Lexer) Consumed()

Consumed reads all remaining bytes from the input, publishing an error if there is anything but whitespace remaining.

func (*Lexer) Delim Uses

❖
func (r *Lexer) Delim(c byte)

Delim consumes a token and verifies that it is the given delimiter.

❖
func (r *Lexer) Error() error

❖
func (r *Lexer) Int8() int8

func (*Lexer) Int8Str Uses

❖
func (r *Lexer) Int8Str() int8

func (*Lexer) IntStr Uses

❖
func (r *Lexer) IntStr() int

func (*Lexer) Interface Uses

❖
func (r *Lexer) Interface() interface{}

Interface fetches an interface{} analogous to the 'encoding/json' package.

func (*Lexer) IsDelim Uses

❖
func (r *Lexer) IsDelim(c byte) bool

IsDelim returns true if there was no scanning error and next token is the given delimiter.

func (*Lexer) IsNull Uses

❖
func (r *Lexer) IsNull() bool

IsNull returns true if the next token is a null keyword.

func (*Lexer) IsStart Uses

❖
func (r *Lexer) IsStart() bool

IsStart returns whether the lexer is positioned at the start of an input string.

func (*Lexer) JsonNumber Uses

❖
func (r *Lexer) JsonNumber() json.Number

JsonNumber fetches and json.Number from 'encoding/json' package. Both int, float or string, contains them are valid values

func (*Lexer) Null Uses

❖
func (r *Lexer) Null()

Null verifies that the next token is null and consumes it.

func (*Lexer) Ok Uses

❖
func (r *Lexer) Ok() bool

Ok returns true if no error (including io.EOF) was encountered during scanning.

func (*Lexer) Raw Uses

❖
func (r *Lexer) Raw() []byte

Raw fetches the next item recursively as a data slice

func (*Lexer) Skip Uses

❖
func (r *Lexer) Skip()

Skip skips a single token.

func (*Lexer) SkipRecursive Uses

❖
func (r *Lexer) SkipRecursive()

SkipRecursive skips next array or object completely, or just skips a single token if not an array/object.

Note: no syntax validation is performed on the skipped data.

func (*Lexer) String Uses

❖
func (r *Lexer) String() string

String reads a string literal.

func (*Lexer) StringIntern Uses

❖
func (r *Lexer) StringIntern() string

StringIntern reads a string literal, and performs string interning on it.

func (*Lexer) Uint Uses

❖
func (r *Lexer) Uint() uint

func (*Lexer) Uint16 Uses

❖
func (r *Lexer) Uint16() uint16

func (*Lexer) Uint16Str Uses

❖
func (r *Lexer) Uint16Str() uint16

func (*Lexer) Uint32 Uses

❖
func (r *Lexer) Uint32() uint32

func (*Lexer) Uint32Str Uses

❖
func (r *Lexer) Uint32Str() uint32

func (*Lexer) Uint64 Uses

❖
func (r *Lexer) Uint64() uint64

func (*Lexer) Uint64Str Uses

❖
func (r *Lexer) Uint64Str() uint64

func (*Lexer) Uint8 Uses

❖
func (r *Lexer) Uint8() uint8

func (*Lexer) Uint8Str Uses

❖
func (r *Lexer) Uint8Str() uint8

func (*Lexer) UintStr Uses

❖
func (r *Lexer) UintStr() uint

func (*Lexer) UintptrStr Uses

❖

func (*Lexer) UnsafeBytes Uses

❖
func (r *Lexer) UnsafeBytes() []byte

UnsafeBytes returns the byte slice if the token is a string literal.

func (*Lexer) UnsafeFieldName Uses

❖
func (r *Lexer) UnsafeFieldName(skipUnescape bool) string

UnsafeFieldName returns current member name string token

func (*Lexer) UnsafeString Uses

❖
func (r *Lexer) UnsafeString() string

UnsafeString returns the string value if the token is a string literal.

Warning: returned string may point to the input buffer, so the string should not outlive the input buffer. Intended pattern of usage is as an argument to a switch statement.

func (*Lexer) WantColon Uses

❖
func (r *Lexer) WantColon()

WantColon requires a colon to be present before fetching next token.

func (*Lexer) WantComma Uses

❖
func (r *Lexer) WantComma()

WantComma requires a comma to be present before fetching next token.

type LexerError Uses

❖
type LexerError struct {
    Reason string
    Offset int
    Data   string
}
