Examples of org.eclipse.jdt.core.dom.ITypeBinding

org.eclipse.jdt.core.dom.ITypeBinding
A type binding represents fully-resolved type. There are a number of different kinds of type bindings:
- a class - represents the class declaration; possibly with type parameters
- an interface - represents the class declaration; possibly with type parameters
- an enum - represents the enum declaration (enum types do not have have type parameters)
- an annotation - represents the annotation type declaration (annotation types do not have have type parameters)
- an array type - array types are referenced but not explicitly declared
- a primitive type (including the special return type void) - primitive types are referenced but not explicitly declared
- the null type - this is the special type of null
- a type variable - represents the declaration of a type variable; possibly with type bounds
- a wildcard type - represents a wild card used as a type argument in a parameterized type reference
- a raw type - represents a legacy non-parameterized reference to a generic type
- a parameterized type - represents an copy of a type declaration with substitutions for its type parameters
- a capture - represents a capture binding

     * The rule is that the declared, generic type, is the single canonical type.
