JavaTM 2 Platform Std. Ed. v1.4.2
- All Implemented Interfaces:
- public abstract class StreamPrintService
- extends Object
- implements PrintService
This class extends
PrintService and represents a
print service that prints data in different formats to a
client-provided output stream.
This is principally intended for services where
the output format is a document type suitable for viewing
The output format must be declared as a mime type.
This is equivalent to an output document flavor where the
representation class is always "java.io.OutputStream"
An instance of the
StreamPrintService class is
obtained from a
Note that a
StreamPrintService is different from a
PrintService, which supports a
StreamPrintService always requires an output
stream, whereas a
PrintService optionally accepts a
has no default destination for its formatted output.
StreamPrintService is expected to generate
a format useful in other contexts.
StreamPrintService's are not expected to support the Destination attribute.

protected StreamPrintService(OutputStream out)
- Constructs a StreamPrintService object.
out - stream to which to send formatted print data.
public OutputStream getOutputStream()
- Gets the output stream.
- the stream to which this service will send formatted print data.
public abstract String getOutputFormat()
- Returns the document format emitted by this print service.
Must be in mimetype format, compatible with the mime type
components of DocFlavors @see DocFlavor.
- mime type identifying the output format.
public void dispose()
- Disposes this
If a stream service cannot be re-used, it must be disposed
to indicate this. Typically the client will call this method.
Services which write data which cannot meaningfully be appended to
may also dispose the stream. This does not close the stream. It
just marks it as not for further use by this service.
public boolean isDisposed()
- Returns a
boolean indicating whether or not
StreamPrintService has been disposed.
If this object has been disposed, will return true.
Used by services and client applications to recognize streams
to which no further data should be written.
- if this
StreamPrintService has been disposed
