- antlr.BaseAST
- - antlr.CommonAST
  - - org.hibernate.hql.internal.ast.tree.Node
    - - org.hibernate.hql.internal.ast.tree.SqlNode
      - org.hibernate.hql.internal.ast.tree.HqlSqlWalkerNode
        
        org.hibernate.hql.internal.ast.tree.AbstractSelectExpression
        
        org.hibernate.hql.internal.ast.tree.SimpleCaseNode

所有已实现的接口:

antlr.collections.AST, Serializable, ExpectedTypeAwareNode, InitializeableNode, SelectExpression
```
public class SimpleCaseNode
extends AbstractSelectExpression
implements SelectExpression, ExpectedTypeAwareNode
```
Models what ANSI SQL terms a simple case statement. This is a CASE expression in the form
```
 CASE [expression]
     WHEN [firstCondition] THEN [firstResult]
     WHEN [secondCondition] THEN [secondResult]
     ELSE [defaultResult]
 END
 
```

    从接口复制的说明: SelectExpression
    
    Returns the data type of the select expression.
    
    指定者:
    
    getDataType 在接口中 SelectExpression
    
    覆盖:
    
    getDataType 在类中 SqlNode
    
    返回:
    
    The data type of the select expression.
  - setScalarColumnText
```
public void setScalarColumnText(int i)
                         throws antlr.SemanticException
```
    从接口复制的说明: SelectExpression
    
    Appends AST nodes that represent the columns after the current AST node. (e.g. 'as col0_O_')
    
    指定者:
    
    setScalarColumnText 在接口中 SelectExpression
    
    参数:
    
    i - The index of the select expression in the projection list.
    
    抛出:
    
    antlr.SemanticException - if a semantic error occurs
  - setExpectedType
```
public void setExpectedType(Type expectedType)
```
    指定者:
    
    setExpectedType 在接口中 ExpectedTypeAwareNode
  - getExpectedType
```
public Type getExpectedType()
```
    指定者:
    
    getExpectedType 在接口中 ExpectedTypeAwareNode
