public DataSourceInputStream(DataSource dataSource,
                             DataSpec dataSpec)
```
    Parameters:
    
    dataSource - The DataSource from which the data should be read.
    
    dataSpec - The DataSpec defining the data to be read from dataSource.
- Method Detail
  - bytesRead
```
public long bytesRead()
```
    Returns the total number of bytes that have been read or skipped.
  - open
```
public void open()
          throws IOException
```
    Optional call to open the underlying DataSource.
    Calling this method does nothing if the DataSource is already open. Calling this method is optional, since the read and skip methods will automatically open the underlying DataSource if it's not open already.
    
    Throws:
    
    IOException - If an error occurs opening the DataSource.
  - read
```
public int read()
         throws IOException
```
    Specified by:
    
    read in class InputStream
    
    Throws:
    
    IOException
  - read

public int read(byte[] buffer)
         throws IOException
```
    Overrides:
    
    read in class InputStream
    
    Throws:
    
    IOException
  - read

public int read(byte[] buffer,
                int offset,
                int length)
