java.lang.Objectorg.eclipse.gmf.runtime.common.core.util.EnumeratedType
public abstract class EnumeratedType
An enumeration of constants based on the typesafe enum pattern.
Constructor Summary | |
---|---|
protected |
EnumeratedType(java.lang.String name,
int ordinal)
Concrete subclasses should define a private static field to generate ordinals and a private constructor as follows:
private static int nextOrdinal = 0;
private Subclass(String name) {
super(name, nextOrdinal++);
}
|
Method Summary | |
---|---|
boolean |
equals(java.lang.Object object)
Indicates whether some other object is "equal to" this enumerated type. |
java.lang.String |
getName()
Retrieves the value of the name instance variable. |
int |
getOrdinal()

protected abstract java.util.List |
getValues()
Retrieves the list of constants for this enumerated type. |
int |
hashCode()
Retrieves a hash code value for this enumerated type. |
protected java.lang.Object |
