Capacity(IImmutableSet<NodeMetrics>)

Remaining capacity for each node. The value is between 0.0 and 1.0, where 0.0 means no remaining capacity (full utilization) and 1.0 means full remaining capacity (zero utilization).

Declaration
public abstract IImmutableDictionary<Address, double> Capacity(IImmutableSet<NodeMetrics> nodeMetrics)
Parameters
Type Name Description
IImmutableSet<NodeMetrics> nodeMetrics
Returns
Type Description
IImmutableDictionary<Address, double>

Weights(IImmutableDictionary<Address, double>)

Converts the capacity values to weights. The node with lowest capacity gets weight 1 (lowest usable capacity is 1%) and other nodes gets weights proportional to their capacity compared to the node with lowest capacity.

Declaration
public IImmutableDictionary<Address, int> Weights(IImmutableDictionary<Address, double> capacity)
Parameters
Type Name Description
IImmutableDictionary<Address, double> capacity
Returns
Type Description
IImmutableDictionary<Address, int>

Weights(IImmutableSet<NodeMetrics>)

The weights per address, based on the nodeMetrics.

Declaration
public IImmutableDictionary<Address, int> Weights(IImmutableSet<NodeMetrics> nodeMetrics)
Parameters

IImmutableSet<NodeMetrics> nodeMetrics
Returns
Type Description
