Example 11 with Field

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

the class JniEnv method ToReflectedField.

/**
 * <h3>jobject ToReflectedField(JNIEnv *env, jclass cls, jfieldID fieldID, jboolean isStatic);

 * <p>
 * Converts a field ID derived from cls to a java.lang.reflect.Field object. isStatic must be
 * set to JNI_TRUE if fieldID refers to a static field, and JNI_FALSE otherwise.
 * <p>
 * Throws OutOfMemoryError and returns 0 if fails.
