IdBuilderInt (JGAlgo - Parent 0.4.0 API)

All Superinterfaces:

IdBuilder<Integer>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface IdBuilderInt
extends IdBuilder<Integer>
```
Builder for unique identifiers of vertices or edges in an IntGraph.
An IntGraph allows adding vertices by either providing an identifier (IntGraph.addVertex(int)) or without (IntGraph.addVertexInt()). If no identifier is provided, the graph will generate one using an instance of this interface. The same is true for edges, see IntGraph.addEdge(int, int, int) and IntGraph.addEdge(int, int). The graph expose its vertex and edge builders using IntGraph.vertexBuilder() and IntGraph.edgeBuilder(), which may return null. The identifiers returned by this interface must be unique in the graph.
This interface is shared for both vertices and edges, but an instance of this interface is used only for one of them at a time.
This interface is a specific version of IdBuilder for IntGraph.

@Deprecated
default Integer build(Set<Integer> existing)
```
    Deprecated.
    use build(IntSet) instead to avoid unnecessary un/boxing
    
    Builds a unique identifier for a vertex or an edge.
    
    Specified by:
    
    build in interface IdBuilder<Integer>
    
    Parameters:
    
    existing - the identifiers of the vertices or edges already in the graph
    
    Returns:
    
    a unique identifier
  - build
```
int build(IntSet existing)
```
    Builds a unique identifier for a vertex or an edge.
    
    Parameters:
    
    existing - the identifiers of the vertices or edges already in the graph
    
    Returns:
    
    a unique identifier
  - defaultBuilder
```
static IdBuilderInt defaultBuilder()
```
    Get an default builder for int identifiers.
    The returned factory may be passed to GraphFactory.setVertexBuilder(IdBuilder).
    
    Returns:
    
    a default builder for int identifiers
  - defaultFactory
```
static Supplier<IdBuilderInt> defaultFactory()
```
    Get an default factory for int identifiers.
    The returned factory may be passed to GraphFactory.setVertexFactory(Supplier).
    
    Returns:
    
    a default factory for int identifiers
