Enum data type in EMF

问题

How to get information about an attribute of enum type?

I have an EClass with an attribute which is type of enum. I know you can use the following code to determine the type of an attribute

EDataType type = attr.getEAttributeType();
if (type == EcorePackage.Literals.EINT);
//do something
if (type == EcorePackage.Literals.EENUM);
// do something

But the line (type == EcorePackage.Literals.EENUM) doesn't work, thus I am wondering how to determine an attribute is type of eEnum, given any Ecore metamodels.

回答1:

For enumerated types you could use either of:

type instanceof EEnum
type.eClass() == EcorePackage.eINSTANCE.getEEnum()
