Types

type Lexer 

type Lexer interface {
	SetTypeSystemInput(input []byte) error
	ExtendTypeSystemInput(input []byte) error
	ResetTypeSystemInput()
	SetExecutableInput(input []byte) error
	AppendBytes(input []byte) (err error)
	Read() (tok token.Token)
	Peek(ignoreWhitespace bool) keyword.Keyword
	ByteSlice(reference document.ByteSliceReference) document.ByteSlice
	TextPosition() position.Position
}

Lexer is the interface used by the Parser to lex tokens

type ManualAstMod added in v1.2.0 

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

ManualAstMod keeps functions to manually modify the parsed ast

func NewManualAstMod added in v1.2.0 

func NewManualAstMod(p *Parser) *ManualAstMod

func (*ManualAstMod) AppendFieldToSelectionSet added in v1.2.0 

func (m *ManualAstMod) AppendFieldToSelectionSet(fieldRef, setRef int)

func (*ManualAstMod) DeleteFieldFromSelectionSet added in v1.2.0 

func (m *ManualAstMod) DeleteFieldFromSelectionSet(fieldRef, setRef int)

func (*ManualAstMod) MergeArgIntoFieldArguments added in v1.3.0 

func (m *ManualAstMod) MergeArgIntoFieldArguments(argRef, fieldRef int)

func (*ManualAstMod) PutArgument added in v1.3.0 

func (m *ManualAstMod) PutArgument(argument document.Argument) int

func (*ManualAstMod) PutArgumentSet added in v1.3.0 

func (m *ManualAstMod) PutArgumentSet(set document.ArgumentSet) int

func (*ManualAstMod) PutField added in v1.2.0 

func (m *ManualAstMod) PutField(field document.Field) int

func (*ManualAstMod) PutLiteralBytes added in v1.3.0 

func (m *ManualAstMod) PutLiteralBytes(literal []byte) (byteSliceRef document.ByteSliceReference, ref int, err error)

PutLiteralBytes appends a literal to the end of the lexer input storage before appending the lexer will read forward until EOF by doing this we make sure there's no unexpected content at the end of the input this step is necessary because clients like curl end a request by appending a newline ('\n') the parser does not expect a newLine at the end of the input so we have to read over it

func (*ManualAstMod) PutLiteralString added in v1.3.0 

func (m *ManualAstMod) PutLiteralString(literal string) (byteSliceRef document.ByteSliceReference, ref int, err error)

func (*ManualAstMod) PutValue added in v1.3.0 

func (m *ManualAstMod) PutValue(value document.Value) int

func (*ManualAstMod) SetMutationTypeName added in v1.3.0 

func (m *ManualAstMod) SetMutationTypeName(name document.ByteSliceReference)

func (*ManualAstMod) SetQueryTypeName added in v1.3.0 

func (m *ManualAstMod) SetQueryTypeName(name document.ByteSliceReference)

func (*ManualAstMod) SetSubscriptionTypeName added in v1.3.0 

func (m *ManualAstMod) SetSubscriptionTypeName(name document.ByteSliceReference)

type Option

	SelectionSets              []document.SelectionSet

	ByteSliceReferences []document.ByteSliceReference
	Integers            []int32
	Floats              []float32
	Booleans            [2]bool
