Public constructors

DataSourceInputStream

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 functions

bytesRead

fun bytesRead(): Long

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

close

fun close(): Unit

Throws
`java.io.IOException`

open

fun open(): Unit

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

fun read(): Int

Throws
`java.io.IOException`

read

fun read(buffer: ByteArray!): Int

Throws
`java.io.IOException`

read

fun read(buffer: ByteArray!, offset: Int, length: Int): Int

Throws
`java.io.IOException`
