public boolean isNodeAccepted(BaseNodeContext node,
 org.jppf.management.NodeSelector selector)

Determine whether the specified selector accepts the specified node.

Parameters:

node - the node to check.

selector - the node selector used as a filter.

Returns:

a set of BaseNodeContext instances.

isNodeAccepted

public boolean isNodeAccepted(String nodeUuid,
 org.jppf.management.NodeSelector selector)

Specified by:

isNodeAccepted in interface org.jppf.management.forwarding.NodeSelectionProvider

getChannels

public Set<BaseNodeContext> getChannels(org.jppf.management.NodeSelector selector)

Get a set of channels based on a NodeSelector.

Parameters:

selector - the node selector used as a filter.

Returns:

a set of BaseNodeContext instances.

getChannels

public Set<BaseNodeContext> getChannels(org.jppf.management.NodeSelector selector,
 boolean includePeers,
 boolean forForwarding)

Get a set of channels based on a NodeSelector.

Parameters:

selector - the node selector used as a filter.

includePeers - whether peer drivers should be counted as nodes and included.
