Types

type Iterator

type Iterator interface {
	Next() interface{}
	HasNext() bool
}

Iterator is a simple iterator interface.

type PeekableIterator

type PeekableIterator struct {
	Iter Iterator
	// contains filtered or unexported fields
}

PeekableIterator wraps an iterator and provides the ability to peek.

func (*PeekableIterator) HasNext

func (p *PeekableIterator) HasNext() bool

HasNext returns true if there is more to read from the iterator and false otherwise.

func (*PeekableIterator) Next

func (p *PeekableIterator) Next() interface{}

Next returns the next element and advances the iterator.

func (*PeekableIterator) Peek

func (p *PeekableIterator) Peek() interface{}

Peek returns the next element without moving the iterator.
