- All Implemented Interfaces:
StateObject
public class NumericLiteralStateObject extends SimpleStateObject
Exact numeric literals support the use of Java integer literal syntax as well as SQL exact numeric literal syntax. Approximate literals support the use of Java floating point literal syntax as well as SQL approximate numeric literal syntax.Appropriate suffixes may be used to indicate the specific type of a numeric literal in accordance with the Java Language Specification.
