public class NcharAsciiStream
extends AsciiStream

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 NcharAsciiStream is a variant of the SQLJ AsciiStream that always implies an NCHAR form of use.

Constructor Detail

NcharAsciiStream

public NcharAsciiStream(java.io.InputStream in)
Creates an Ascii-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 AsciiStream as an input (or in-out) parameter to an executable sql operation.

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

NcharAsciiStream

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

NcharAsciiStream

public NcharAsciiStream(AsciiStream as)
Creates an Ascii-valued input stream with Nchar form of use from an existing Ascii input stream.
Parameters:
the - Ascii stream
