- All Implemented Interfaces:
it.unimi.dsi.lang.FlyweightPrototype<ImmutableGraph>
- Direct Known Subclasses:
IntegerTriplesArcLabelledImmutableGraph
An abstract arc-labelled immutable graph that throws an
UnsupportedOperationException
on all random-access methods.
The main purpose of this class is to be used as a base for the numerous anonymous classes that do not support random access.

Method Details
-
successorArray
public int[] successorArray(int x) Throws anUnsupportedOperationException.- Overrides:
successorArrayin classImmutableGraph- Parameters:
x- a node.- Returns:
- an array whose first elements are the successors of the node; the array must not be modified by the caller.
-
labelArray
Throws anUnsupportedOperationException.- Overrides:
labelArrayin classArcLabelledImmutableGraph- Returns:
- an array whose first elements are the labels of the arcs going out of
x; the array must not be modified by the caller.
-
outdegree
public int outdegree(int x) Throws anUnsupportedOperationException.- Specified by:
outdegreein classImmutableGraph- Parameters:
x- a node.- Returns:
- the outdegree of the given node.
-
nodeIterator
Throws anUnsupportedOperationException.- Overrides:
nodeIteratorin classArcLabelledImmutableGraph- Parameters:
x- the node from which the iterator will iterate.- Returns:
- an
ArcLabelledNodeIteratorfor accessing nodes, successors and their labels sequentially. - See Also:
-
successors
Throws anUnsupportedOperationException.- Specified by:
successorsin classArcLabelledImmutableGraph- Parameters:
x- a node.- Returns:
- a lazy iterator over the successors of the node.
-
randomAccess
public boolean randomAccess()Returns false.- Specified by:
randomAccessin classImmutableGraph- Returns:
- false.
-
copy
Throws anUnsupportedOperationException.- Specified by:
copyin interfaceit.unimi.dsi.lang.FlyweightPrototype<ImmutableGraph>- Specified by:
copyin classArcLabelledImmutableGraph- Returns:
- a flyweight copy of this immutable graph.
