Example 62 with Method

use of com.oracle.truffle.espresso.impl.Method in project graal by oracle.

the class JniEnv method UnregisterNatives.

/**
 * <h3>jint UnregisterNatives(JNIEnv *env, jclass clazz);</h3>
 * <p>
 * Unregisters native methods of a class. The class goes back to the state before it was linked
 * or registered with its native method functions.
 * <p>
 * This function should not be used in normal native code. Instead, it provides special programs
 * a way to reload and relink native libraries.
 *
 * @param clazz a Java class object.
 *            <p>
 *            Returns 0 on success; returns a negative value on failure.
