setNodesSelectionStrategy

public void setNodesSelectionStrategy(LoadBalancerNodesSelectionStrategy strategy)

Set the connection address selection strategy to use.

Parameters:

strategy - connection address selection strategy

getNodesSelectionStrategy

public LoadBalancerNodesSelectionStrategy getNodesSelectionStrategy()

Get the connection address selection strategy.

Returns:

connection address selection strategy

setAllowedTiers

public void setAllowedTiers(Set<String> allowedTiers)

Set the allowed node tier names for creating connections with. All active nodes in an allowed tier will be used for connection creation. If the set is empty, all nodes from tiers will be used.

Parameters:

allowedTiers - set of allowed tier names

getAllowedTiers

public Set<String> getAllowedTiers()

Returns:

set of allowed tier names

setForbiddenTiers

public void setForbiddenTiers(Set<String> forbiddenTiers)

Set the forbidden node tier names for creating connections with. All nodes in a forbidden tier will be skipped for connection creation. If the set is empty, no tiers will be skipped.

Parameters:

forbiddenTiers - set of forbidden tier names

getForbiddenTiers

public Set<String> getForbiddenTiers()

Get the set of forbidden tier names for filtering out nodes for connection.

Returns:

set of forbidden tier names
