Types

type ConcurrentShardedCounts

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

ShardedCounts keeps counts for a sharded data structure This implementation is concurrently safe

func NewConcurrentShardedCounts

func NewConcurrentShardedCounts() *ConcurrentShardedCounts

NewShardedCounts creates a new ShardedCounts

func (*ConcurrentShardedCounts) GetTotal

func (counts *ConcurrentShardedCounts) GetTotal() int64

GetTotal gets total count

func (*ConcurrentShardedCounts) IsInterfaceNil

func (counts *ConcurrentShardedCounts) IsInterfaceNil() bool

IsInterfaceNil returns true if there is no value under the interface

func (*ConcurrentShardedCounts) PutCounts

func (counts *ConcurrentShardedCounts) PutCounts(shardName string, value int64)

PutCounts registers counts for a shard

func (*ConcurrentShardedCounts) String

func (counts *ConcurrentShardedCounts) String() string

type ConcurrentShardedCountsWithSize

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

ConcurrentShardedCountsWithSize keeps counts (with sizes) for a sharded data structure

func NewConcurrentShardedCountsWithSize

func NewConcurrentShardedCountsWithSize() *ConcurrentShardedCountsWithSize

NewConcurrentShardedCountsWithSize creates a new ShardedCountsWithSize

func (*ConcurrentShardedCountsWithSize) GetTotal

type Counts

type Counts interface {
	GetTotal() int64
	String() string
	IsInterfaceNil() bool
}

Counts is an interface to interact with counts

type CountsWithSize

type CountsWithSize interface {
	Counts
	GetTotalSize() int64
}

CountsWithSize is an interface to interact with counts

type NullCounts

type NullCounts struct {
}

NullCounts implements null object pattern for counts

func (*NullCounts) GetTotal

func (counts *NullCounts) GetTotal() int64

GetTotal returns -1

func (*NullCounts) GetTotalSize

func (counts *NullCounts) GetTotalSize() int64

GetTotalSize returns -1

func (*NullCounts) IsInterfaceNil

func (counts *NullCounts) IsInterfaceNil() bool

IsInterfaceNil returns true if there is no value under the interface

func (*NullCounts) String

func (counts *NullCounts) String() string

String returns a placeholder
