The JNI compiler maps Java primitive types to the JNI-equivalent C++ types:
Java type |
JNI-equivalent C++ type |
|---|---|
boolean |
jboolean |
byte |
jbyte |
char |
jchar |
double |
jdouble |
float |
jfloat |
int |
jint |
long |
jlong |
short |
jshort |
Arrays of Java primitive types are mapped to proxy classes in the java_lang_Object.hpp header file, as follows:
Java type |
C++ type |
C++ type with namespaces |
|---|---|---|
boolean[] |
java_booleanArray |
java::booleanArray |
byte[] |
java_byteArray |
java_byteArray |
char[] |
java_charArray |
java_charArray |
double[] |
java_doubleArray |
java_doubleArray |
float[] |
java_floatArray |
java_floatArray |
int[] |
java_intArray |
java_intArray |
long[] |
java_longArray |
java_longArray |
short[] |
java_shortArray |
java_shortArray |
The Java null type is mapped to the java_null proxy class; java::null with namespaces.
