BTLPolicy BlockToLive policy for the pvt data
type BTLPolicy interface {
// GetBTL returns BlockToLive for a given namespace and collection
GetBTL(ns string, coll string) (uint64, error)

func ConstructBTLPolicy(collInfoProvider collectionInfoProvider) BTLPolicy
ConstructBTLPolicy constructs an instance of LSCCBasedBTLPolicy
LSCCBasedBTLPolicy implements interface BTLPolicy. This implementation loads the BTL policy from lscc namespace which is populated with the collection configuration during chaincode initialization
type LSCCBasedBTLPolicy struct {
// contains filtered or unexported fields
}
func (p *LSCCBasedBTLPolicy) GetBTL(namesapce string, collection string) (uint64, error)
GetBTL implements corresponding function in interface `BTLPolicyMgr`
func (p *LSCCBasedBTLPolicy) GetExpiringBlock(namesapce string, collection string, committingBlock uint64) (uint64, error)
GetExpiringBlock implements function from the interface `BTLPolicy`
