AttributeWriter (Geotools modules 31-SNAPSHOT API)

All Known Implementing Classes:

JoiningAttributeWriter
```
public interface AttributeWriter
```
- Added hasNext to support the FeatureWriter API. - Changed order of writer parameters to match Collections, JDBC API. - Added IOExceptions on all methods. - Do we want AttributeWriters to know about the schema and perform validation??

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`close()`
`int`	`getAttributeCount()`	The number of attributes this reader can read, i.e the length of a row.
`AttributeDescriptor`	`getAttributeType(int i)`	Retrieve the AttributeType at the given index.
`boolean`	`hasNext()`	Query whether there are other rows in the attribute writer.
`void`	`next()`	Advance the AttributeWriter, all calls to write will correspond to the same set of attributes until next is called again.
`void`	`write(int position, Object attribute)`	Write the given attribute value at the position indicated.

- Method Detail
  - getAttributeCount
```
int getAttributeCount()
```
    The number of attributes this reader can read, i.e the length of a row.
  - getAttributeType
```
AttributeDescriptor getAttributeType(int i)
                              throws ArrayIndexOutOfBoundsException
```
    Retrieve the AttributeType at the given index.
    
    Throws:
    
    ArrayIndexOutOfBoundsException
  - next
```
void next()
   throws IOException
```
    Advance the AttributeWriter, all calls to write will correspond to the same set of attributes until next is called again.
    
    Throws:
    
    IOException
  - write
```
void write(int position,
           Object attribute)
    throws IOException
```
    Write the given attribute value at the position indicated. Implementations can choose to immediately flush the write or buffer it.
    
    Throws:
    
    IOException
  - close
```
void close()
    throws IOException
```
    Throws:
    
    IOException
  - hasNext
```
boolean hasNext()
         throws IOException
```
    Query whether there are other rows in the attribute writer.
    
    Throws:
    
    IOException
