public interface NativeMapped

Provide conversion for a Java type to and from a native type. Function and Structure will use this interface to determine how to map a given Java object into a native type.

Implementations of this interface must provide a no-args constructor.

See ToNativeConverter for a list of allowable native types.

Parameters:

nativeValue - Java representation of the native type to be converted.

context - Context in which the conversion is taking place.

Returns:

Converted object.

toNative

Object toNative()

Convert this object into a supported native type.

Returns:

Java representation of the original Java object converted to a native type.

nativeType

Class<?> nativeType()

Indicate the native type used by this converter.

Returns:

Java class representation of the native type.
