Class DefaultTypeMapper

java.lang.Object

com.sun.jna.DefaultTypeMapper

All Implemented Interfaces:

TypeMapper

Direct Known Subclasses:

W32APITypeMapper

public class DefaultTypeMapper
extends java.lang.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).
