Enum DotDirection

java.lang.Object
  java.lang.Enum<DotDirection>
      edu.mit.csail.sdg.alloy4graph.DotDirection

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<DotDirection>

public enum DotDirection
extends java.lang.Enum<DotDirection>

Immutable; this defines the set of possible edge directions.

Thread Safety: Can be called only by the AWT event thread.

Method Detail

values

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

Returns:

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

valueOf

public static DotDirection valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

getDotText

public java.lang.String getDotText()

Returns the String that should be written into the dot file for this value, when used with the given palette.
