// contains filtered or unexported fields
}

func New ¶
func New(limit uint64, stopChan <-chan struct{}) *MemoryManager
New create and initialize new memory manager object used to acquire memory. If the amount of memory required is not available, the process will be blocked until memory became available
func (*MemoryManager) MemoryAvailable ¶
func (mm *MemoryManager) MemoryAvailable() uint64
MemoryAvailable returns current memory available
func (*MemoryManager) MemoryLimit ¶
func (mm *MemoryManager) MemoryLimit() uint64
MemoryLimit returns max memory allowed
func (*MemoryManager) Request ¶
func (mm *MemoryManager) Request(amount uint64, priority bool) bool
Request will try to get memory requested, return true if succeed if failed, the storageClient process will be blocked until the memory can be allocated
func (*MemoryManager) Return ¶
func (mm *MemoryManager) Return(amount uint64)
Return will return memory requested and processing memory requests in the waitlist
func (*MemoryManager) SetMemoryLimit ¶
func (mm *MemoryManager) SetMemoryLimit(amount uint64) string
