List of objectFieldOffset() Examples

Examples of objectFieldOffset()

com.oracle.truffle.api.nodes.NodeUtil.FieldOffsetProvider.objectFieldOffset()
sun.misc.Unsafe.objectFieldOffset()

Retrieves the offset value of the {@link Field} for use by other methodsin this class.
@param field The {@link Field} to retrieve the offset for. @return The offset value.

Examples of com.oracle.truffle.api.nodes.NodeUtil.FieldOffsetProvider.objectFieldOffset()

            final Field fieldOffsetProviderField = NodeUtil.class.getDeclaredField("unsafeFieldOffsetProvider");
            fieldOffsetProviderField.setAccessible(true);
            final FieldOffsetProvider fieldOffsetProvider = (FieldOffsetProvider) fieldOffsetProviderField.get(null);


            final Field firstPrimitiveField = ObjectStorage.class.getDeclaredField("primitiveStorageLocation01");
            return fieldOffsetProvider.objectFieldOffset(firstPrimitiveField);
        } catch (NoSuchFieldException | IllegalAccessException e) {
            throw new RuntimeException(e);
