Functions

Types

type Table

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

Table wraps the underling DB, so all the table's data is stored with a prefix in underling DB

func New

func New(db ethdb.KeyValueStore, prefix []byte) *Table

func (*Table) Close

func (t *Table) Close() error

func (*Table) Compact

func (t *Table) Compact(start []byte, limit []byte) error

func (*Table) Delete

func (t *Table) Delete(key []byte) error

func (*Table) Drop

func (t *Table) Drop()

Drop the whole database.

func (*Table) Get

func (t *Table) Get(key []byte) ([]byte, error)

func (*Table) Has

func (t *Table) Has(key []byte) (bool, error)

func (*Table) NewBatch

func (*Table) NewIteratorWithPrefix

func (t *Table) NewIteratorWithPrefix(itPrefix []byte) ethdb.Iterator

func (*Table) NewIteratorWithStart

func (t *Table) NewIteratorWithStart(start []byte) ethdb.Iterator

func (Table) NewTable
