Constructor Details

ByteArrayOrigin

public ByteArrayOrigin(byte[] origin)

Constructs a new instance for the given origin.

Parameters:

origin - The origin, not null.

Throws:

NullPointerException - if origin is null.

Method Details

getByteArray

public byte[] getByteArray()

Gets this origin as a byte array, if possible.

No conversion should occur when calling this method.

Overrides:

getByteArray in class AbstractOrigin<byte[], AbstractOrigin.ByteArrayOrigin>

Returns:

this origin as a byte array, if possible.

getChannel

protected Channel getChannel(OpenOption... options)
                      throws IOException

Description copied from class: AbstractOrigin

Gets this origin as a Channel, if possible.

Overrides:

getChannel in class AbstractOrigin<byte[], AbstractOrigin.ByteArrayOrigin>

Parameters:

options - Options specifying how a file-based origin is opened, ignored otherwise.

Returns:

A new Channel on the origin.

Throws:

IOException - If an I/O error occurs.

See Also:

• AbstractOrigin.getChannel(Class, OpenOption...)

getInputStream

public InputStream getInputStream(OpenOption... options)
                           throws IOException

Gets this origin as an InputStream, if possible.

The options parameter is ignored since a byte[] does not need an OpenOption to be read.

Overrides:

getInputStream in class AbstractOrigin<byte[], AbstractOrigin.ByteArrayOrigin>

Parameters:

options - options specifying how the file is opened

Returns:

this origin as an InputStream, if possible.

Throws:

IOException - if an I/O error occurs.

getReader

public Reader getReader(Charset charset)
                 throws IOException

Description copied from class: AbstractOrigin

Gets a new Reader on the origin, buffered by default.

Overrides:

getReader in class AbstractOrigin<byte[], AbstractOrigin.ByteArrayOrigin>

Parameters:

charset - the charset to use for decoding, null maps to the default Charset.

Returns:

a new Reader on the origin.

Throws:

IOException - if an I/O error occurs opening the file.

size

public long size()
          throws IOException

Description copied from class: AbstractOrigin

Gets the size of the origin, if possible.

Overrides:

size in class AbstractOrigin<byte[], AbstractOrigin.ByteArrayOrigin>

Returns:

the size of the origin in bytes or characters.

Throws:

IOException - if an I/O error occurs.
