## com.sun.jna
Class DefaultTypeMapper

    java.lang.Object
      com.sun.jna.DefaultTypeMapper

All Implemented Interfaces:
  TypeMapper

Direct Known Subclasses:
  W32APITypeMapper

    public class DefaultTypeMapper

extends Object
implements TypeMapper

Provide custom mappings to and from native types. The default lookup checks classes corresponding to converters in the order added; if the class to be converted is an instance of the converter's registered class, the converter will be used.

Derived classes should install additional converters using `addToNativeConverter(java.lang.Class, com.sun.jna.ToNativeConverter)` and/or `addFromNativeConverter(java.lang.Class, com.sun.jna.FromNativeConverter)` in the default constructor. Classes for primitive types will automatically register for the corresponding Object type and vice versa (i.e. you don't have to register both `int.class` and `Integer.class`). If you want different mapping behavior than the default, simply override `getToNativeConverter(java.lang.Class)` and `getFromNativeConverter(java.lang.Class)`.
