public class NcharUnicodeStream
extends UnicodeStream

An InputStream-derived class whose bytes should be interpreted as ASCII. When passing an InputStream as an input parameter to a executable sql operation, both the length of the InputStream and the way to interpret its bytes must be specified.

The NcharUnicodeStream is a variant of the SQLJ UnicodeStream that always implies an NCHAR form of use.

Constructor Detail

NcharUnicodeStream

public NcharUnicodeStream(java.io.InputStream in)
Creates an Unicode-valued input stream with Nchar form of use with an uninitialized length.

Note: the length attribute must be set via a call to setLength() before use of an UnicodeStream as an input (or in-out) parameter to an executable sql operation.

Parameters:
in - the InputStream to interpret as an UnicodeStream with an NCHAR form of use.

NcharUnicodeStream

public NcharUnicodeStream(java.io.InputStream in,
                          int length)
Creates an Unicode-valued input stream with Nchar form of use of given length.
Parameters:
in - the InputStream to interpret as an UnicodeStream with an NCHAR form of use.
length - the length in bytes of the UnicodeStream

NcharUnicodeStream

public NcharUnicodeStream(UnicodeStream as)
Creates an Unicode-valued input stream with Nchar form of use from an existing Unicode input stream.
Parameters:
the - Unicode stream
