Interface IConstantPoolEntry

All Known Subinterfaces:

IConstantPoolEntry2, IConstantPoolEntry3

All Known Implementing Classes:

ConstantPoolEntry, ConstantPoolEntry2

public interface IConstantPoolEntry

Description of a constant pool entry as described in the JVM specifications. Its contents is initialized according to its kind. This interface may be implemented by clients. Because of that questionable choice, clients may have to cast to IConstantPoolEntry3 to get access to the relevant content.

Since:

2.0
