Public constructors

DataSourceInputStream

public DataSourceInputStream(DataSource dataSource, DataSpec dataSpec)

Parameters
`DataSource dataSource`	The `DataSource` from which the data should be read.
`DataSpec dataSpec`	The `DataSpec` defining the data to be read from `dataSource`.

Public methods

bytesRead

public long bytesRead()

Returns the total number of bytes that have been read or skipped.

close

public void close()

Throws
`java.io.IOException`

open

public void open()

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
`java.io.IOException`	If an error occurs opening the `DataSource`.

read

public int read()

Throws
`java.io.IOException`

read

public int read(byte[] buffer)

Throws
`java.io.IOException`

read

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

Throws
`java.io.IOException`
