- net.ontopia.persistence.query.sql.SQLTuple

All Implemented Interfaces:

SQLValueIF
```
public class SQLTuple
extends Object
implements SQLValueIF
```
INTERNAL: SQL value: tuple. Represents a list of nested SQL values. The arity is the same as the total arity of its nested values.

```
public int getType()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Returns the value class type. The type is represented by one of the constants in the SQLValueIF interface.
    
    Specified by:
    
    getType in interface SQLValueIF
  - getArity
```
public int getArity()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Returns the [column] arity of the value. The number represents the number of "columns" the value spans, i.e. its composite width.
    
    Specified by:
    
    getArity in interface SQLValueIF
  - getValueArity
```
public int getValueArity()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Returns the value arity of the value. This number refers to the number of nested values this value contains including itself. Most values therefore have a value arity of 1. Nested values may have an arity higher than 1. SQLTuple is currently the only nested value type.
    
    Specified by:
    
    getValueArity in interface SQLValueIF
  - getAlias
```
public String getAlias()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: The column alias to use if this value is included in the projection. The SQL select syntax is typically like "select value as from foo".
    
    Specified by:
    
    getAlias in interface SQLValueIF
  - setAlias
```
public void setAlias(String alias)
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Sets the column alias.
    
    Specified by:
    
    setAlias in interface SQLValueIF
  - isReference
```
public boolean isReference()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Returns true if this value is a reference to another.
    
    Specified by:
    
    isReference in interface SQLValueIF
  - getReference
```
public SQLValueIF getReference()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Returns the referenced value if one exists.
    
    Specified by:
    
    getReference in interface SQLValueIF
  - getValues

public SQLValueIF[] getValues()
```

  - getValueType
```
public Class getValueType()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Returns the value type.
    
    Specified by:
    
    getValueType in interface SQLValueIF
  - setValueType
```
public void setValueType(Class vtype)
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Sets the value type.
    
    Specified by:
    
    setValueType in interface SQLValueIF
  - getFieldHandler
```
public FieldHandlerIF getFieldHandler()
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Returns the field handler for the columns.
    
    Specified by:
    
    getFieldHandler in interface SQLValueIF
  - setFieldHandler
```
public void setFieldHandler(FieldHandlerIF fhandler)
```
    Description copied from interface: SQLValueIF
    
    INTERNAL: Sets the field handler for the value.
    
    Specified by:
    
    setFieldHandler in interface SQLValueIF
