All Implemented Interfaces:

com.oracle.graal.pointsto.infrastructure.GraphProvider, AnnotatedElement, jdk.vm.ci.meta.InvokeTarget, jdk.vm.ci.meta.JavaMethod, jdk.vm.ci.meta.ModifiersProvider, jdk.vm.ci.meta.ResolvedJavaMethod

public class JNIFieldAccessorMethod
extends EntryPointCallStubMethod

Generated method for accessing a field via JNI. An accessor is specific to the basic type of the field, to static or non-static fields, and can either read or write the field. The generated method implements one of the following JNI functions:

• GetObjectField
• GetBooleanField
• GetByteField
• GetCharField
• GetShortField
• GetIntField
• GetLongField
• GetFloatField
• GetDoubleField
• SetObjectField
• SetBooleanField
• SetByteField
• SetCharField
• SetShortField
• SetIntField
• SetLongField
• SetFloatField
• SetDoubleField
• GetStaticObjectField
• GetStaticBooleanField
• GetStaticByteField
• GetStaticCharField
• GetStaticShortField
• GetStaticIntField
• GetStaticLongField
• GetStaticFloatField
• GetStaticDoubleField
• SetStaticObjectField
• SetStaticBooleanField
• SetStaticByteField
• SetStaticCharField
• SetStaticShortField
• SetStaticIntField
• SetStaticLongField
• SetStaticFloatField
• SetStaticDoubleField
