Examples of org.eclipse.jdt.core.IType

org.eclipse.jdt.core.IType
Represents either a source type in a compilation unit (either a top-level type, a member type, a local type or an anonymous type) or a binary type in a class file. Enumeration classes and annotation types are subkinds of classes and interfaces, respectively.
Note that the element name of an anonymous source type is always empty.
If a binary type cannot be parsed, its structure remains unknown. Use IJavaElement.isStructureKnown to determine whether this is the case.

The children are of type IMember, which includes IField, IMethod, IInitializer and IType. The children are listed in the order in which they appear in the source or class file.
@noimplement This interface is not intended to be implemented by clients.
