convertBlobToByteArray

protected static byte[] convertBlobToByteArray(Blob data)
                                        throws TeiidException

Throws:

TeiidException

convertToByteArray

public static byte[] convertToByteArray(Object data)
                                 throws TeiidException,
                                        IOException

Throws:

TeiidException

IOException

convertToByteArray

public static byte[] convertToByteArray(InputStream is)
                                 throws IOException

Throws:

IOException

convertToByteArray

public static byte[] convertToByteArray(InputStream is,
                                        int length)
                                 throws IOException

Returns the given input stream's contents as a byte array. If a length is specified (ie. if length != -1), only length bytes are returned. Otherwise all bytes in the stream are returned. Note this does close the stream, even if not all bytes are written, because the buffering does not guarantee the end position.

Throws:

IOException - if a problem occurred reading the stream.
