Method Summary

private boolean	assignAllProxyCategories() Assigns semantic Filecategories to all files of all proxies prequisites: this.videoFiles and this.requests and this.proxies must be set before
private void	assignCategoriesToProxyfiles(X2XProxy proxy) Assigns semantic Filecategories to all files of 1 proxy prequisites: this.videoFiles and this.requests and this.proxies must be set before
private void	assignFileCategories() as medisyn does not retain the info about file-categories: assign a RANDOM category to each file prequisites: this.videoFiles and this.fileCategories must be set before
private void	formGroups(boolean equalNrOfProxiesPerGroup) Iterates through proxies and forms groups NOTE: this only works here locally if only semantical closeness is considered! else: -->code must be moved to PlabServers prequisites: this.videoFiles and this.proxies and this.fileCategories must be set before
java.util.Vector<X2XProxy>	generateProxies(boolean equalNrOfProxiesPerGroup) generate the proxies according to the requests and videoFiles, calculate the Proxy-Groups prequisites: this.videoFiles and this.requests and this.proxies must be set before

Method Detail

assignFileCategories

private void assignFileCategories()
                           throws java.lang.Exception

as medisyn does not retain the info about file-categories: assign a RANDOM category to each file prequisites: this.videoFiles and this.fileCategories must be set before

Throws:

java.lang.Exception

formGroups

private void formGroups(boolean equalNrOfProxiesPerGroup)
                 throws java.lang.Exception

Iterates through proxies and forms groups NOTE: this only works here locally if only semantical closeness is considered! else: -->code must be moved to PlabServers prequisites: this.videoFiles and this.proxies and this.fileCategories must be set before

Parameters:

equalNrOfProxiesPerGroup - - if true, then this function will try to form groups with equal nr of nodes in each group, otherwise, the nodes will be assigned to groups straight ahead.

Throws:

java.lang.Exception

printProxyGroups

public static void printProxyGroups(java.util.Vector<ProxyGroup> proxyGroups)
                             throws java.lang.Exception

prints the proxy-grups and their proxies to stdout

Parameters:

proxyGroups - - Vector containing the groups and proxies

Throws:

java.lang.Exception

printProxyGroups

public static void printProxyGroups(ProxyGroup proxyGroup)
                             throws java.lang.Exception

prints the proxy-grup and its proxies to stdout

Parameters:

proxyGroup - - the group and its proxies

Throws:

java.lang.Exception

assignAllProxyCategories

assignCategoriesToProxyfiles

private void assignCategoriesToProxyfiles(X2XProxy proxy)
                                   throws java.lang.Exception,
                                          java.lang.CloneNotSupportedException
