SQLOutputImpl (Java Platform SE 8 )

java.lang.Object
- javax.sql.rowset.serial.SQLOutputImpl

All Implemented Interfaces:

SQLOutput
```
public class SQLOutputImpl
extends Object
implements SQLOutput
```
The output stream for writing the attributes of a custom-mapped user-defined type (UDT) back to the database. The driver uses this interface internally, and its methods are never directly invoked by an application programmer.
When an application calls the method PreparedStatement.setObject, the driver checks to see whether the value to be written is a UDT with a custom mapping. If it is, there will be an entry in a type map containing the Class object for the class that implements SQLData for this UDT. If the value to be written is an instance of SQLData, the driver will create an instance of SQLOutputImpl and pass it to the method SQLData.writeSQL. The method writeSQL in turn calls the appropriate SQLOutputImpl.writeXXX methods to write data from the SQLData object to the SQLOutputImpl output stream as the representation of an SQL user-defined type.

              throws SQLException
```
    Creates a new SQLOutputImpl object initialized with the given vector of attributes and type map. The driver will use the type map to determine which SQLData.writeSQL method to invoke. This method will then call the appropriate SQLOutputImpl writer methods in order and thereby write the attributes to the new output stream.
    
    Parameters:
    
    attributes - a Vector object containing the attributes of the UDT to be mapped to one or more objects in the Java programming language
    
    map - a java.util.Map object containing zero or more entries, with each entry consisting of 1) a String giving the fully qualified name of a UDT and 2) the Class object for the SQLData implementation that defines how the UDT is to be mapped
    
    Throws:

```
public void writeObject(SQLData x)
                 throws SQLException

    Writes to the stream the data contained in the given SQLData object. When the SQLData object is null, this method writes an SQL NULL to the stream. Otherwise, it calls the SQLData.writeSQL method of the given object, which writes the object's attributes to the stream.
    The implementation of the method SQLData.writeSQ calls the appropriate SQLOutputImpl.writeXXX method(s) for writing each of the object's attributes in order. The attributes must be read from an SQLInput input stream and written to an SQLOutputImpl output stream in the same order in which they were listed in the SQL definition of the user-defined type.
    
    Specified by:
    
    writeObject in interface SQLOutput
    
    Parameters:
    
    x - the object representing data of an SQL structured or distinct type
    
    Throws:
    
    SQLException - if the SQLOutputImpl object is in use by a SQLData object attempting to write the attribute values of a UDT to the database.
  - writeRef

public void writeRef(Ref x)
              throws SQLException
```

```
    Writes a Struct object in the Java programming language to this SQLOutputImpl object. The driver converts this value to an SQL structured type before returning it to the database.
    This method should be used when an SQL structured type has been mapped to a Struct object in the Java programming language (the standard mapping). The method writeObject should be used if an SQL structured type has been custom mapped to a class in the Java programming language.
    
    Specified by:
