Method Summary

Map<?,Future<Void>>	execute(String tag, int count, Template template, Set<NodeMetadata> goodNodes, Map<NodeMetadata,Exception> badNodes, com.google.common.collect.Multimap<NodeMetadata,CustomizationResponse> customizationResponses) This implementation gets a list of acceptable node names to encode the tag into, then it simultaneously runs the nodes and applies options to them.
protected String	getNextName(String tag, Template template) Get a name using a random mechanism that still ties all nodes in a tag together.
protected Set<String>	getNextNames(String tag, Template template, int count) Find the next node names that can be used.

Method Detail

execute

public Map<?,Future<Void>> execute(String tag,
                                   int count,
                                   Template template,
                                   Set<NodeMetadata> goodNodes,
                                   Map<NodeMetadata,Exception> badNodes,
                                   com.google.common.collect.Multimap<NodeMetadata,CustomizationResponse> customizationResponses)

This implementation gets a list of acceptable node names to encode the tag into, then it simultaneously runs the nodes and applies options to them.

Specified by:

execute in interface CreateNodesInGroupThenAddToSet

getNextNames

protected Set<String> getNextNames(String tag,
                                   Template template,
                                   int count)

Find the next node names that can be used. These will be derived from the tag and the template. We will pre-allocate a specified quantity, and attempt to verify that there is no name conflict with the current service.

Parameters:

tag -

count -

template -

Returns:

getNextName

protected String getNextName(String tag,
                             Template template)

Get a name using a random mechanism that still ties all nodes in a tag together. This implementation will pass the tag and a hex formatted random number to the configured naming convention.
