Package com.progress.open4gl

Class ProBlob

java.lang.Object

com.progress.open4gl.ProBlob

All Implemented Interfaces:

Serializable, Blob

public class ProBlob
extends Object
implements Blob, Serializable

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.
