Types

type Cache

type Cache struct {

	// for verify process
	Bases   []*typdefs.BaseRow
	TaBases map[string]*typdefs.TaBaseRow
	// contains filtered or unexported fields
}

Cache stores the latest status of one RAC client and commands.

func NewCache

ClearCommands clears the client commands.

func (*Cache) CompareNonce

func (c *Cache) CompareNonce(n uint64) bool

CompareNonce checks the returned nonce match or not.

func (*Cache) GetBases

func (c *Cache) GetBases() []*typdefs.BaseRow

GetBases returns the baases.
