Javadoc

Returns the value of the 'Default Value' attribute.

It represents the default value that feature must take on when an explicit value has not been set. Specifically, it may be non-null if the feature has an ETypedElement#getEType. If the #getDefaultValueLiteral is null, it is simply the eType's intrinsic EClassifier#getDefaultValue. Otherwise, if the eType is an EDataType and the defaultValueLiteral is non-null, it is the object created by the factory's EFactory#createFromString method when invoked with those two objects as parameters.
