Types

type Argument

type Argument struct {

	// hash table bucket related information.
	IBucket, NBucket uint64

	vm.OperatorBase
	// contains filtered or unexported fields
}

func NewArgument

func NewArgument() *Argument

func (*Argument) Call

func (arg *Argument) Call(proc *process.Process) (vm.CallResult, error)

Call is the execute method of minus operator it built a hash table for right relation first. use values from left relation to probe and update the hash table. and preserve values that do not exist in the hash table.

func (*Argument) Prepare

func (arg *Argument) Prepare(proc *process.Process) error

func (*Argument) Release

func (arg *Argument) Release()

func (*Argument) String

func (arg *Argument) String(buf *bytes.Buffer)

func (Argument) TypeName
