Method Summary

Modifier and Type	Method and Description
Decision	getCanAllocateDecision() Returns whether the shard is allowed to be allocated to the node.
float	getCurrentWeight() Returns the current weight of the node if the shard is not added to the node.
Decision.Type	getNodeDecisionType() Returns the decision to rebalance to the node.
float	getWeightWithShardAdded() Returns the weight of the node if the shard is added to the node.
boolean	isBetterWeightThanCurrent() Returns whether the weight of the node is better than the weight of the node where the shard currently resides.
boolean	isDeltaAboveThreshold() Returns if the weight delta by assigning to this node was above the threshold to warrant a rebalance.
