Class ProBlob

java.lang.Object
  |
  +--com.progress.open4gl.ProBlob

All Implemented Interfaces:

java.sql.Blob

public class ProBlob

extends java.lang.Object

implements java.sql.Blob

The representation (mapping) in the Java programming language of an SQL BLOB value. An SQL BLOB is a built-in type that stores a Binary Large Object as a column value in a row of a database table. The driver implements Blob using an SQL locator(BLOB), which means that a Blob object contains a logical pointer to the SQL BLOB data rather than the data itself. A Blob object is valid for the duration of the transaction in which is was created.

Constructor Summary

ProBlob(byte[] data)
Constructor taking a byte array.

Method Summary

java.io.InputStream	getBinaryStream()
byte[]	getBytes(long pos, int length)
long	length()
long	position(java.sql.Blob pattern, long start)
long	position(byte[] pattern, long start)
java.io.OutputStream	setBinaryStream(long pos)
int	setBytes(long pos, byte[] bytes)
int	setBytes(long pos, byte[] bytes, int offset, int len)
void	truncate(long len)
