- All Implemented Interfaces:
Serializable
,Comparable<LiteralType>
,java.lang.constant.Constable
Some
Expression
can have a "literal",
this enumeration is used to visit an Expression
and to retrieve the right value.
Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
- Since:
- 2.3
- Version:
- 2.4
