Method Detail
-
get
java.lang.Object get(int index)
- Returns:
- the element at the specified index
-
getElements
java.lang.Object[] getElements()
As the tuple is supposed to be immutable, do not modify the returned array.- Returns:
- the array containing all elements of this Tuple
-
getDistinctElements
<T> java.util.Set<T> getDistinctElements()
- Returns:
- the set containing all distinct elements of this Tuple, cast as type T
-
getSize
int getSize()
- Returns:
- number of elements
-
invertIndex
java.util.Map<java.lang.Object,java.lang.Integer> invertIndex()
Calculates an inverted index of the elements of this pattern. For each element, the index of the (last) occurrence is calculated.- Returns:
- the inverted index mapping each element of this pattern to its index in the array
-
invertIndexWithMupliplicity
java.util.Map<java.lang.Object,java.util.List<java.lang.Integer>> invertIndexWithMupliplicity()
Calculates an inverted index of the elements of this pattern. For each element, the index of all of its occurrences is calculated.- Returns:
- the inverted index mapping each element of this pattern to its index in the array
-
toImmutable
Tuple toImmutable()
