                throws java.lang.IllegalArgumentException,
                       java.rmi.RemoteException

Creates a binary file entry. When the binary file is published, the file name is used as the name. If a different name is preferred, use the constructor that takes the input stream and the name of the entry.

There is no default MIME type. To set the MIME type for the entry, use setMIMEType(java.lang.String).

Parameters:

file - The binary file.

Throws:

java.lang.IllegalArgumentException - If a null file is specified.

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

BinaryFileEntry

                       java.rmi.RemoteException

Creates a binary file entry. When the binary file is published, the input stream will be consumed until end-of-file.

There is no default MIME type. To set the MIME type for the entry, use setMIMEType(java.lang.String).

Parameters:

inputStream - The input stream of the binary file.

name - The name of the binary file entry. This name will be used as the name of the entry when publishing the package.

Deprecated. Use getInputStream()which now supports remote input streams.

Gets the input stream for this binary file entry. Because input streams are not remotable, this method will throw a RemoteException if it is invoked on a remote object. Distributed applications should utilize getRemoteInputStream(java.lang.Object)in order to obtain the input stream.

Specified by:

getInputStream in interface com.sas.io.InputStreamProviderInterface

Specified by:

getInputStream in interface BinaryFileEntryInterface

Parameters:

streamID - The stream description should be null; it will be ignored.

Returns:

The input stream that can be used for reading the contents of the binary file entry.

Throws:

java.lang.IllegalStateException - 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.

Deprecated. Use getInputStream()which now supports remote input streams.

Get the binary file as a remote input stream. If your application runs in a distributed environment, it is suggested that you use RemoteInputStream. InputStreams are not remote objects.

Specified by:

getRemoteInputStream in interface com.sas.io.InputStreamProviderInterface

Specified by:

getRemoteInputStream in interface BinaryFileEntryInterface

Parameters:

streamID - The stream description should be null ;it will be ignored.

Returns:

RemoteInputStream The file as a remote input stream.

Throws:

java.lang.IllegalStateException - If the package containing this entry is already closed.

Deprecated. this method no longer needed as getInputStream() will return an input stream that can be used in a remote environment

Check if getInputStream(java.lang.Object)will succeed. See getInputStream(java.lang.Object)to determine whether this method should be used.

Specified by:

hasInputStream in interface com.sas.io.InputStreamProviderInterface

Specified by:

hasInputStream in interface BinaryFileEntryInterface

Returns:

non-null if getInputStream(java.lang.Object) would succeed; throws UnmarshalException if it would fail

Throws:

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

java.lang.IllegalStateException - If the package containing this entry is already closed.

java.rmi.RemoteException - if a network I/O error occurs.

consumeStream

public void consumeStream()
                   throws java.io.IOException,
                          java.rmi.RemoteException,
                          java.lang.IllegalStateException

Consume and close the input stream provided on the constructor. If an input stream is provided on the entry's constructor, then it does not get consumed until the package is published. This method may be invoked to force the stream to get consumed and closed immediately instead of waiting until the publish occurs.

Throws:

java.lang.IllegalStateException - If the package containing this entry is already closed.

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

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

closeEntry

protected void closeEntry()

finalize

protected void finalize()
                 throws java.lang.Throwable

At finalize time, cleanup temporary files if necessary.

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable
