Interface SyntheticAttribute

All Superinterfaces:: Attribute<SyntheticAttribute>, ClassElement, ClassFileElement, FieldElement, MethodElement

public sealed interface SyntheticAttribute extends Attribute<SyntheticAttribute>, ClassElement, MethodElement, FieldElement

Models the Synthetic attribute (JVMS 4.7.8), which marks a class member as implementation-specific artifacts.

This attribute can appear on classes, methods, and fields, and permits multiple instances in a structure. It has no data dependency.

This attribute was introduced in the Java SE Platform version 1.1, major version 45.

API Note:

This attribute has been largely superseded by the ACC_SYNTHETIC modifier in newer class files. See Elements.Origin for a more in-depth description about the differences between synthetic and implicit (mandated) constructs generated by compilers.
