public class AsciiStream

extends StreamWrapper

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. Therefore, an InputStream cannot be passed directly, but rather must be an instance of AsciiStream, BinaryStream or UnicodeStream.

Constructor Detail

AsciiStream

public AsciiStream(java.io.InputStream in)

Creates an Ascii-valued input stream 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.

AsciiStream

public AsciiStream(java.io.InputStream in,
                   int length)

Creates an Ascii-valued input stream of given length.

Parameters:

in - the InputStream to interpret as an AsciiStream.

length - the length in bytes of the AcsiiStream
