Description

Indicates whether the field represents the data in a binary large object (BLOB) field.

Call IsBlob to determine whether the field represents BLOB data. For example, before using the GetData or SetData method, call IsBlob to determine whether the method can be used. The IsBlob method for TField always returns false. Descendants of TField that implement blob fields override this method to indicate that they represent BLOB data.
