Class NumericLiteralStateObject
java.lang.Object
org.eclipse.persistence.jpa.jpql.tools.model.query.AbstractStateObject
org.eclipse.persistence.jpa.jpql.tools.model.query.SimpleStateObject
org.eclipse.persistence.jpa.jpql.tools.model.query.NumericLiteralStateObject
- All Implemented Interfaces:
StateObject
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.
