## javax.print
Class StreamPrintService

    java.lang.Object
      |
      +--javax.print.StreamPrintService

All Implemented Interfaces:
  PrintService

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 or archiving. 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 `StreamPrintServiceFactory` instance.

Note that a `StreamPrintService` is different from a `PrintService`, which supports a `Destination` attribute. A `StreamPrintService` always requires an output stream, whereas a `PrintService` optionally accepts a `Destination`. A `StreamPrintService` has no default destination for its formatted output. Additionally a `StreamPrintService` is expected to generate output in a format useful in other contexts. StreamPrintService's are not expected to support the Destination attribute.

Constructor Summary
`protected` | `StreamPrintService(OutputStream out)` Constructs a StreamPrintService object.

Method Summary
`void` | `dispose()` Disposes this `StreamPrintService`.
`abstract String` | `getOutputFormat()` Returns the document format emitted by this print service.
`OutputStream` | `getOutputStream()` Gets the output stream.
`boolean` | `isDisposed()` Returns a `boolean` indicating whether or not this `StreamPrintService` has been disposed.

Constructor Detail

### StreamPrintService

    protected StreamPrintService(OutputStream out)

  Constructs a StreamPrintService object.

Parameters:
  `out` - stream to which to send formatted print data.

Method Detail

### getOutputStream

    public OutputStream getOutputStream()

  Gets the output stream.

  Returns:
    the stream to which this service will send formatted print data.

### getOutputFormat

    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.

  Returns:
    mime type identifying the output format.

### dispose

    public void dispose()

  Disposes this `StreamPrintService`. 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.

### isDisposed

    public boolean isDisposed()

  Returns a `boolean` indicating whether or not this `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.

  Returns:
    if this `StreamPrintService` has been disposed
