All Known Implementing Classes:

ViewerEntry

public interface ViewerEntryInterface
extends EntryInterface, com.sas.io.InputStreamProviderInterface, com.sas.io.ReaderProviderInterface

The ViewerEntryInterface provides a mechanism for setting and getting the attributes of a viewer entry. In the MVA Publishing Framework, a viewer is a custom-written template that contains HTML tags for formatting result set package content for view-only transports, such as e-mail. The viewer file is applied to the package during package publishing. A viewer file is particularly useful for rendering a SAS data set in a tabular format for viewing in e-mail. Also, it is useful for streaming dynamic information in the form of a binary file or a URL for inclusion in an electronic newsletter format.

The viewer is not used for rendering purposes in the Java Publishing Framework, but viewer entries can be published and retrieved.

Method Detail

getEncoding

java.lang.String getEncoding()
                             throws java.rmi.RemoteException,
                                    TransportException

Returns the encoding of viewer.

Returns:

String The encoding of the viewer; can be null.

Throws:

TransportException - If the transport encounters an error getting the encoding.

java.rmi.RemoteException - If a network anomaly is encountered.

java.lang.IllegalStateException - If the package is already closed.

setEncoding

void setEncoding(java.lang.String encoding)
                 throws java.lang.IllegalStateException,
                        java.rmi.RemoteException

Sets the viewer encoding.

If this is a text viewer, the encoding is used when constructing the Reader that is returned by getReader and getRemoteReader, and it is used to publish the viewer.

If this is an HTML viewer, the encoding of the HTML viewer is published as metadata along with the viewer entry. When published, the HTML viewer is parsed. If the charset= attribute is specified in the META tag, this encoding value will be used. If not found, the value set using this method will be used. Otherwise, a default encoding of ISO-8859-1 will be set.

Parameters:

encoding - The encoding for this viewer.

Throws:

java.lang.IllegalStateException - If the entry is read only or if the package containing this entry has already been closed.

java.rmi.RemoteException - If a network anomaly is encountered

getViewerType

int getViewerType()
                  throws TransportException,
                         java.rmi.RemoteException

Returns the type of viewer, HTML or text.

Returns:

int The type of viewer. Supported viewer types include HTML_VIEWER or TEXT_VIEWER.

Throws:

TransportException - If the transport encounters an error getting the viewer type.

java.rmi.RemoteException - If a network anomaly is encountered

java.lang.IllegalStateException - If the package is already closed.

getName

                         throws java.rmi.RemoteException,
                                TransportException

Returns the name of the file.

Returns:

String The name of the file.

Throws:

TransportException - If the transport encounters an error getting the name of the file.

java.rmi.RemoteException - If a network anomaly is encountered.

java.lang.IllegalStateException - If the package is already closed.

                             throws java.rmi.RemoteException,
                                    TransportException

Returns the MIME type associated with this viewer entry. The user-specified MIME type is assigned when the viewer entry is published.

Returns:

String The MIME type associated with this file; can be null.

Throws:

TransportException - If the transport encounters an error getting the MIME type.

java.rmi.RemoteException - If a network anomaly is encountered.

java.lang.IllegalStateException - If the package is already closed.

Throws:

java.lang.IllegalStateException - If invoked on a text viewer or if the package containing this entry is already closed.

java.rmi.UnmarshalException - If invoked on a remote object.

java.io.IOException - If an error occurs constructing the input stream.

java.rmi.RemoteException - If a network anomaly is encountered.
