ByteArrayDataSource_OLD

public ByteArrayDataSource_OLD(byte[] data)

Method Detail

createInputStream

public java.io.InputStream createInputStream()

Description copied from interface: DataSource

Creates a new InputStream that allows to read out the document's binary data from the beginning.

Specified by:

createInputStream in interface DataSource

Returns:

Returns the InputStream with the binary data.

getLength

public int getLength()

Description copied from interface: DataSource

Returns the length (number of bytes) of the stream.

Specified by:

getLength in interface DataSource

Returns:

Returns the length (number of bytes) of the stream.

getAsByteArray

public byte[] getAsByteArray()

Description copied from interface: DataSource

Returns the data of this DataSource as a byte array for random read only access.

Calling this method indicates that you need a byte array for random read only access. The DataSource implementation should of course cache this byte array to avoid too much memory usage.

Performance analysis has shown that the libraries internally convert the streams to byte arrays and that file system access is very slow.

Never write to this byte array!

Specified by:

getAsByteArray in interface DataSource

Returns:

Returns the data of this DataSource as a byte array for random read only access.

getMimeType

public java.lang.String getMimeType()

Description copied from interface: DataSource

Returns the mime type of the data.

Specified by:

getMimeType in interface DataSource

Returns:

Returns the mime type of the data.

getCharacterEncoding

public java.lang.String getCharacterEncoding()

Description copied from interface: DataSource

Returns the character encoding of the data.

This makes only sense for character based mime types.

Specified by:

getCharacterEncoding in interface DataSource

Returns:

Returns the character encoding of the data or null if no encoding is applicable (e.g. if the data is binary).
