Constructor Detail

DynamicClusterImpl

public DynamicClusterImpl()

DynamicClusterImpl

public DynamicClusterImpl(java.util.Map properties, Entity parent)
Instantiate a new DynamicCluster. Valid properties are:
Parameters:
properties - The properties of the cluster (those corresponding to config keys will be visible to created children by inheritance, but to set properties on children explicitly, use the memberSpec or factory)
parent - the entity that owns this cluster (optional)
