FromElement (Hibernate API Documentation) - Hibernate 3.2.3 正式版 API 英文文档
org.hibernate.hql.ast.tree
Class FromElement
java.lang.Object
antlr.BaseAST
antlr.CommonAST
org.hibernate.hql.ast.tree.Node
org.hibernate.hql.ast.tree.SqlNode
org.hibernate.hql.ast.tree.HqlSqlWalkerNode
org.hibernate.hql.ast.tree.FromElement
- All Implemented Interfaces:
- antlr.collections.AST, DisplayableNode, InitializeableNode, Serializable
- Direct Known Subclasses:
- ImpliedFromElement
- public class FromElement
- extends HqlSqlWalkerNode
- implements DisplayableNode
Represents a single mapped class mentioned in an HQL FROM clause. Each
class reference will have the following symbols:
- A class name - This is the name of the Java class that is mapped by Hibernate.
- [optional] an HQL alias for the mapped class.
- A table name - The name of the table that is mapped to the Java class.
- A table alias - The alias for the table that will be used in the resulting SQL.
