Interface TypeDescriptor.OfField<F extends TypeDescriptor.OfField<F>>

Type Parameters:: F - the class implementing TypeDescriptor.OfField

All Superinterfaces:: TypeDescriptor

All Known Subinterfaces:: ClassDesc

All Known Implementing Classes:: Class

Enclosing interface:: TypeDescriptor

public static interface TypeDescriptor.OfField<F extends TypeDescriptor.OfField<F>> extends TypeDescriptor

An entity that has a field type descriptor. Field descriptors conforming to JVMS 4.3.2 can be described nominally via Class::describeConstable; otherwise they cannot be described nominally.
