Class BlobStreamingParameter

java.lang.Object

org.drizzle.jdbc.internal.common.query.parameters.BlobStreamingParameter

All Implemented Interfaces:

ParameterHolder

public class BlobStreamingParameter
extends Object
implements ParameterHolder

Holds a blobstreaming parameter. protocol works like this when uploading a stream: 1. upload stream to http://:// 2. execute the insert using the blob reference returned

Constructor and Description
BlobStreamingParameter(InputStream is, String host, String port, String schema) Create a new StreamParameter.

Method Summary

Modifier and Type	Method and Description
long	length() Returns the length of the parameter - this is the length of the blob reference Since we don't know the length of the reference before it has been uploaded, it is uploaded in this method.
int	writeTo(OutputStream os, int offset, int maxWriteSize) Writes the parameter to an outputstream.

Method Detail

writeTo

public final int writeTo(OutputStream os,
                         int offset,
                         int maxWriteSize)
                  throws IOException

Writes the parameter to an outputstream.

the number of bytes written (either maxWriteSize or the length of the parameter)

Throws:

IOException - if we cannot write to the stream

length

public final long length()
                  throws IOException

Returns the length of the parameter - this is the length of the blob reference Since we don't know the length of the reference before it has been uploaded, it is uploaded in this method.
