Constructor Detail

DataSourceInputStream

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

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.
