All Methods
Modifier and Type Method and Description

void setVisited(int index)

• ### Method Detail

• #### setVisited

void setVisited(int index)
Mark the given topological index as visited.
Parameters:
index - the topological index
• #### getVisited

boolean getVisited(int index)
Get if the given topological index has been visited.
Parameters:
index - the topological index
Returns:
true if the given topological index has been visited, false otherwise
• #### clearVisited

void clearVisited(int index)
throws UnsupportedOperationException
Clear the visited state of the given topological index.
Parameters:
index - the index
Throws:
UnsupportedOperationException - if the implementation doesn't support (or doesn't need) clearance. For example, if the factory creates a new instance every time, it is a waste of cycles to reset the state after the search of the Affected Region is done, so an UnsupportedOperationException *should* be thrown.
