Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`close()`	Closes the sink.
`void`	`open(DataSpec dataSpec)`	Opens the sink to consume the specified data.
`void`	`write(byte[] buffer, int offset, int length)`	Consumes the provided data.

- Method Detail
  - open
```
void open(DataSpec dataSpec)
   throws IOException
```
    Opens the sink to consume the specified data.
    Note: If an IOException is thrown, callers must still call close() to ensure that any partial effects of the invocation are cleaned up.
    
    Parameters:
    
    dataSpec - Defines the data to be consumed.
    
    Throws:
    
    IOException - If an error occurs opening the sink.
  - write
```
void write(byte[] buffer,
           int offset,
           int length)
    throws IOException
```
    Consumes the provided data.
    
    Parameters:
    
    buffer - The buffer from which data should be consumed.
    
    offset - The offset of the data to consume in buffer.
    
    length - The length of the data to consume, in bytes.
    
    Throws:
    
    IOException - If an error occurs writing to the sink.
  - close
```
void close()
    throws IOException
```
    Closes the sink.
    Note: This method must be called even if the corresponding call to open(DataSpec) threw an IOException. See open(DataSpec) for more details.
    
    Throws:
    
    IOException - If an error occurs closing the sink.
