IfxBlob classAn IfxBlob represents a BLOB, which is a large block of binary data that allows random access of its contents. You can treat a BLOB in much the same way you treat an operating system file. You can read or write to certain positions in the file without reading or writing through all of the data up to that position.
The IfxBlob internal cursorEach IfxBlob has an internal pointer to a position in the BLOB. This is referred to in this publication as the cursor of the instance.

The IfxBlob internal cursor

Each IfxBlob has an internal pointer to a position in the BLOB. This is referred to in this publication as the cursor of the instance.

The position of the cursor when an IfxBlob object is opened depends on the mode in which it is opened. The section IfxSmartLOBOpenMode enumeration lists the possible modes.

After a read or a write the cursor is moved to the character after the last one affected by the operation. The method IfxBlob.Seek allows you to set the cursor position explicitly.
