iterator

public java.util.Iterator<java.util.HashMap<java.lang.String,java.util.ArrayList<java.lang.String>>> iterator()

Iterator method

Specified by:

iterator in interface java.lang.Iterable<java.util.HashMap<java.lang.String,java.util.ArrayList<java.lang.String>>>

Returns:

True if there is one, false otherwise

next

public java.util.HashMap<java.lang.String,java.util.ArrayList<java.lang.String>> next()

Returns the next IO pair from the trace

Specified by:

next in interface java.util.Iterator<java.util.HashMap<java.lang.String,java.util.ArrayList<java.lang.String>>>
