public class ByteArrayType
Handles byte[]
, mapping it as either of JDBC types - BLOB or (VAR)BINARY.
Can be configured to trim trailing zero bytes.

String |
getClassName()
Returns a full name of Java class that this ExtendedType supports. |
boolean |
isTrimmingBytes()
|
boolean |
isUsingBlobs()
Returns true if byte columns are handled as BLOBs internally. |
Object |
materializeObject(CallableStatement cs,
int index,
int type)
Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method. |
Object |
materializeObject(ResultSet rs,
int index,
int type)
Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method. |
protected byte[] |
readBinaryStream(ResultSet rs,

protected byte[] |
readValueStream(InputStream in,
int streamSize,
int bufSize)
|
void |
setJdbcObject(PreparedStatement st,
Object val,
int pos,
int type,
int scale)
Initializes a single parameter of a PreparedStatement with object value. |
void |
setTrimmingBytes(boolean trimingBytes)
|
void |
setUsingBlobs(boolean usingBlobs)
|
static byte[] |
trimBytes(byte[] bytes)
Strips null bytes from the byte array, returning a potentially smaller array that contains no trailing zero bytes. |
boolean |
validateProperty(Object source,
String property,
Object value,
DbAttribute dbAttribute,
ValidationResult validationResult)
Deprecated. since 3.0 as validation should not be done at the DataNode level. |
protected Blob |
writeBlob(byte[] bytes)
