Method Detail

wrap

Blob wrap(Blob blob)

Wrap the given blob in a serializable wrapper.

Parameters:

blob - The blob to be wrapped.

Returns:

The wrapped blob which will be castable to Blob as well as WrappedBlob.

wrap

Clob wrap(Clob clob)

Wrap the given clob in a serializable wrapper.

Parameters:

clob - The clob to be wrapped.

Returns:

The wrapped clob which will be castable to Clob as well as WrappedClob.

wrap

NClob wrap(NClob nclob)

Wrap the given nclob in a serializable wrapper.

Parameters:

nclob - The nclob to be wrapped.

Returns:

The wrapped nclob which will be castable to NClob as well as WrappedNClob.

createBlob

Blob createBlob(byte[] bytes)

Create a BLOB reference encapsulating the given byte array.

Parameters:

bytes - The byte array to wrap as a blob.

Returns:

The created blob, castable to Blob as well as BlobImplementer

createBlob

Blob createBlob(InputStream stream,
                long length)

Create a BLOB reference encapsulating the given binary stream.

Parameters:

stream - The binary stream to wrap as a blob.

length - The length of the stream.

Returns:

The created blob, castable to Blob as well as BlobImplementer

createClob

Clob createClob(String string)

Create a CLOB reference encapsulating the given String data.

Parameters:

string - The String to wrap as a clob.

Returns:

The created clob, castable to Clob as well as ClobImplementer

createClob

Clob createClob(Reader reader,
                long length)

Create a CLOB reference encapsulating the given character data.

Parameters:

reader - The character data reader.

length - The length of the reader data.

Returns:

The created clob, castable to Clob as well as ClobImplementer

createNClob

NClob createNClob(String string)

Create a NCLOB reference encapsulating the given String data.

Parameters:

string - The String to wrap as a NCLOB.

Returns:

The created NCLOB, castable as Clob as well as NClobImplementer. In JDK 1.6 environments, also castable to java.sql.NClob

createNClob

NClob createNClob(Reader reader,
                  long length)

Create a NCLOB reference encapsulating the given character data.

Parameters:

reader - The character data reader.

length - The length of the reader data.

Returns:

The created NCLOB, castable as Clob as well as NClobImplementer. In JDK 1.6 environments, also castable to java.sql.NClob
