Enum Constant Summary

Enum Constants

Enum Constant	Description
DenseGraph	The graph density (# of edges) will be high, a constant fraction of \(O(n^2)\).
FastEdgeLookup	The graph should support fast edge lookup via Graph.getEdge(Object, Object) and Graph.getEdges(Object, Object).
FastEdgeRemoval	The graph should support fast edge removal via Graph.removeEdge(Object).

Method Summary

Modifier and Type	Method	Description
static GraphFactory.Hint	valueOf(String name)	Returns the enum constant of this type with the specified name.

Enum Constant Detail

FastEdgeRemoval

public static final GraphFactory.Hint FastEdgeRemoval

The graph should support fast edge removal via Graph.removeEdge(Object).

FastEdgeLookup

public static final GraphFactory.Hint FastEdgeLookup

The graph should support fast edge lookup via Graph.getEdge(Object, Object) and Graph.getEdges(Object, Object).

DenseGraph

public static final GraphFactory.Hint DenseGraph

The graph density (# of edges) will be high, a constant fraction of \(O(n^2)\).

Method Detail

values

public static GraphFactory.Hint[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (GraphFactory.Hint c : GraphFactory.Hint.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static GraphFactory.Hint valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
