> Here is a comment from David in 2007 in the ByteWrapper class
> * @deprecated
> * NOTE DEJ20071022: deprecating this because we want to save the byte[] directly instead of inside a serialized
> * object, which makes it hard for other apps to use the data, and causes problems if this object is ever updated
> Here is another comment where it's used, in GenericEntity.getBytes()
> if (value instanceof byte[]) {
> return (byte[]) value;
> }
> if (value instanceof org.apache.ofbiz.entity.util.ByteWrapper) {
> // NOTE DEJ20071022: the use of ByteWrapper is not recommended and is deprecated, only old data should be stored that way
> Debug.logWarning("Found a ByteWrapper object in the database for field [" + this.getEntityName() + "." + name + "]; converting to byte[] and returning, but note that you need to update your database to unwrap these objects for future compatibility", module);
> org.apache.ofbiz.entity.util.ByteWrapper wrapper = (org.apache.ofbiz.entity.util.ByteWrapper) value;
> return wrapper.getBytes();
> }
> Here is another related comment (in SqlJdbcUtil.deserializeField())
> // NOTE DEJ20071022: the following code is to convert the byte[] back into an object; if that fails
> //just return the byte[]; this was for the ByteWrapper thing which is now deprecated, so this may
> //be removed in the near future to enhance performance
> Where there is also this code commented out
> //alt 1: binaryInput = rs.getBinaryStream(ind);
> //alt 2: Blob blobLocator = rs.getBlob(ind);
> //if (blobLocator != null) {
> // binaryInput = blobLocator.getBinaryStream();
> //}
> deserializeField() is only used (twice) in SqlJdbcUtil.getValue() and here are the concerned types (11 & 12):
> fieldTypeMap.put("java.lang.Object", 11);
> fieldTypeMap.put("Object", 11);
> fieldTypeMap.put("java.sql.Blob", 12);
> fieldTypeMap.put("Blob", 12);
> fieldTypeMap.put("byte[]", 12);
> fieldTypeMap.put("java.nio.ByteBuffer", 12);
> fieldTypeMap.put("java.nio.HeapByteBuffer", 12);
> And I think we can clean this 2 cases from the ByteWrapper class . So it was 10 years ago, opinions before I open a Jira ?
