Search next token of a certain dataGroup which is not locked.

Parameters:

edge -

Returns:

The next unlocked token or null if there is no unlocked token.

getNextUnlockedTokenIndex

public static int getNextUnlockedTokenIndex(net.kwfgrid.gworkflowdl.structure.Edge edge,
                                            boolean isReadEdge,

                                            int ignoreDataGroups)

Get the index of the next token of a certain dataGroup which is not locked

Parameters:

edge -

dataGroup -

Returns:

The index of the next unlocked token or -1 if there is no unlocked token.

checkDataGroup

public static boolean checkDataGroup(net.kwfgrid.gworkflowdl.structure.Token token,
                                     boolean isReadWriteToken,

                                     int ignoreDataGroup)

Check if the token belongs to a certain data group.

Parameters:

token -

dataGroup -

Returns:

"true" iff the dataGroup is null or if there is no data.group property or if the data.group property equals the dataGroup string.
