Enum Constant Detail

SingleVertex

public static final FrontierEnum SingleVertex

The initial frontier is a single vertex.

AllVertices

public static final FrontierEnum AllVertices

The initial frontier is all vertices.

SampledVertices

public static final FrontierEnum SampledVertices

The initial frontier is an unweighted sample over all of the vertices

Method Detail

values

public static FrontierEnum[] 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 (FrontierEnum c : FrontierEnum.values())
    System.out.println(c);

Returns:

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

valueOf

public static FrontierEnum 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
