Examples of org.eclipse.jdt.core.IMemberValuePair

org.eclipse.jdt.core.IMemberValuePair
Represents a member-value pair of an annotation. The {@link #getValue() value} is represented by an {@link Object}. To get the exact type of this object, use its {@link #getValueKind() value kind}. If this value is an array, {@link #getValue()} returns an instance of {@link Object}[] and the value kind returns the kind of the elements in this array.
This interface is not intended to be implemented or extended by clients.
