Method Detail

getMIMEType

java.lang.String getMIMEType()
                             throws TransportException,
                                    java.rmi.RemoteException,
                                    java.lang.IllegalStateException

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

Returns:

String The MIME type associated with this text file entry; 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 containing this entry is already closed.

setMIMEType

void setMIMEType(java.lang.String mimeType)
                 throws java.lang.IllegalStateException,
                        java.rmi.RemoteException

Sets the MIME type for this text file entry.

Parameters:

mimeType - The MIME type to associate with this text file entry.

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.

getName

java.lang.String getName()
                         throws java.rmi.RemoteException,
                                TransportException,
                                java.lang.IllegalStateException

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 containing this entry is already closed.

setEncoding

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

Sets the encoding of the text file. This method can only be specified when constructing a package to be published. If specified, the encoding is used when constructing the Reader that is returned by getReader and and getRemoteReader, and it is used to publish the file.

Parameters:

encoding - The encoding for this text file.

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

getReader

java.io.Reader getReader(java.lang.Object readerID)
                         throws java.rmi.UnmarshalException,
                                java.io.IOException,
                                java.rmi.RemoteException,
                                java.lang.IllegalStateException

Deprecated. Use getReader() which now supports remote readers.

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

Specified by:

getReader in interface com.sas.io.ReaderProviderInterface

Parameters:

readerID - The reader description should be null; it will be ignored.

Returns:

The reader that can be used for reading the contents of the text file entry.

Throws:

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.

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

getRemoteReader

com.sas.io.RemoteReaderInterface getRemoteReader(java.lang.Object readerID)
                                                 throws java.io.IOException,
                                                        java.rmi.RemoteException,
                                                        java.lang.IllegalStateException

Deprecated. Use getReader() which now supports remote readers.

Get the remote reader for the text file entry. Because readers are not remotable, distributed applications should use remote readers.

Specified by:

getRemoteReader in interface com.sas.io.ReaderProviderInterface

Parameters:

readerID - The reader description should be null; it will be ignored.

Returns:

RemoteReader The remote reader that can be used for reading the contents of the text file entry.

Throws:

java.io.IOException - If an error occurs constructing the remote reader.

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

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

hasReader

java.lang.Object hasReader()
                           throws java.rmi.UnmarshalException,
                                  java.rmi.RemoteException

Deprecated. this method no longer needed as getReader() will return a reader that can be used in a remote environment

Check if getReader(java.lang.Object) will succeeed.

Specified by:

hasReader in interface com.sas.io.ReaderProviderInterface

Returns:

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

Throws:

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

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

getReader

java.io.Reader getReader()
                         throws java.io.IOException,
                                java.rmi.RemoteException,
                                java.lang.IllegalStateException

Gets reader for the text file entry.

Returns:

The reader that can be used for reading the contents of the text file entry.

Throws:

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

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

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

getReader

java.io.Reader getReader(int maxLineLength)
                         throws java.io.IOException,
                                java.rmi.RemoteException,
                                java.lang.IllegalStateException

Gets reader for the text file entry. The maximum line length is by the Requester transport when reading the text file; it identifies the maximum length of any line that will be in the file. This is typically set to some larger value than is actually used. If a huge number is specified, some hosts will adjust this down to a more reasonable value. Lines longer than this specified maxLineLength will be truncated

The maximum line length parameter is only supported by the Requester transport; it will ignored by all other transports.

Parameters:

maxLineLength - the maximum length of any line that will be in the file. This parameter is supported by the Requester transport; it will be ignored by all other delivery transports.

Returns:

The reader that can be used for reading the contents of the text file entry.

Throws:

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

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

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