Interface AnnotationConstantValueEntry

All Superinterfaces:
PoolEntry
All Known Subinterfaces:
DoubleEntry, FloatEntry, IntegerEntry, LongEntry, Utf8Entry
public sealed interface AnnotationConstantValueEntry extends PoolEntry permits DoubleEntry, FloatEntry, IntegerEntry, LongEntry, Utf8Entry
Marker interface for constant pool entries that can represent constant values associated with elements of annotations. They are also the only entries that do not refer to other constant pool entries.
API Note:
An annotation constant value entry alone is not sufficient to determine the annotation constant; for example, an IntegerEntry of 1 can mean true in AnnotationValue.OfBoolean or 1 in AnnotationValue.OfInt.
