Interface LongEntry

All Superinterfaces:
AnnotationConstantValueEntry, ConstantValueEntry, LoadableConstantEntry, PoolEntry
public sealed interface LongEntry extends AnnotationConstantValueEntry, ConstantValueEntry
Models a CONSTANT_Long_info structure, or a long constant, in the constant pool of a class file.

The use of a LongEntry is modeled by a long. Conversions are through ConstantPoolBuilder.longEntry(long) and longValue().

A long entry has a width of 2, making its subsequent constant pool index valid and unusable.

See Java Virtual Machine Specification:
4.4.5 The CONSTANT_Long_info and CONSTANT_Double_info Structures

24
