The sqlj.runtime.AsciiStream, sqlj.runtime.BinaryStream, and
sqlj.runtime.UnicodeStream classes extend sqlj.runtime.StreamWrapper.
sqlj.runtime.StreamWrapper supports methods for specifying the length of
sqlj.runtime.AsciiStream, sqlj.runtime.BinaryStream, and
sqlj.runtime.UnicodeStream objects.
Constructors
StreamWrapper(InputStream)
Format:
protected StreamWrapper(InputStream input-stream)
Creates an sqlj.runtime.StreamWrapper object with an unspecified length.
Parameters:
input-stream
The InputStream object that the sqlj.runtime.StreamWrapper object wraps.
StreamWrapper(InputStream, int)
Format:
protected StreamWrapper(java.io.InputStream input-stream, int length)
Creates an sqlj.runtime.StreamWrapper object with a specified length.
Parameters:
input-stream
The InputStream object that the sqlj.runtime.StreamWrapper object wraps.
length
The length of the InputStream object in bytes.
Methods
getInputStream
Format:
public InputStream getInputStream()
Returns the underlying InputStream object that is wrapped by the
StreamWrapper object.
getLength
Format:
public void getLength()
Returns the length in bytes of the wrapped InputStream object, as specified by
the constructor or in the last call to setLength.
setLength
Format:
