public class NFileInputStream

extends NInputStream

Opens an input stream on a NetWare file or Extended Attribute.

NFileInputStream extends NInputStream by adding convenience constructors for the various custom parameters.

The DataAccessableParameters class can also be used by the user application layer to obtain constant flags for the various constructors of this class, or can instantiate a DataAccessableParameters object and pass it into the NInputStream constructor.

Constructor Detail

NFileInputStream

public NFileInputStream(DataAccessable accessor)
                 throws java.io.IOException

Constructs an NFileInputStream object using default parameters.

Opens an input stream through the specified DataAccessable object, using default parameters.

Parameters:

accessor - The accessor object that will be called to open the stream.

Throws:

java.io.IOException - When an I/O error occurs.

SubordinateAccessOnlyException - If the accessor does not support a stream to itself, for example a directory.

InputStreamNotSupportedException - If the accessor does not support an input stream.

NFileInputStream

public NFileInputStream(DataAccessable accessor,
                        int openFlags)
                 throws java.io.IOException

Constructs an NFileInputStream object with openFlags parameter.

Given an openFlags object, open an input stream through the specified DataAccessable object.

Parameters:

accessor - The accessor object that will be called to open the stream.

openFlags - The flags that are used in opening the stream in different modes.

Throws:

java.io.IOException - When an I/O error occurs.

SubordinateAccessOnlyException - If the accessor does not support a stream to itself, for example a directory.

InputStreamNotSupportedException - If the accessor does not support an input stream.

NFileInputStream

public NFileInputStream(DataAccessable accessor,
                        int openFlags,
                        int dataSelector)
                 throws java.io.IOException

Constructs an NFileInputStream object with openFlags and dataSelector parameters.

Given an openFlags and dataSelector, opens an input stream through the specified DataAccessable object.

Parameters:

accessor - The DataAccessable object that will be called to open the stream.

openFlags - The flags that are used in opening the stream in different modes.

dataSelector - An integral value that allows the individual data stream on a file to be selected.

Throws:

java.io.IOException - When an I/O error occurs.

SubordinateAccessOnlyException - If the accessor does not support a stream to itself, for example a directory.

InputStreamNotSupportedException - If the accessor does not support an input stream.

NFileInputStream

public NFileInputStream(java.lang.String name,
                        DataAccessable accessor)
                 throws java.io.IOException

Constructs an NFileInputStream object in the subordinate input stream with default parameters.

Opens a subordinate input stream through the specified DataAccessable object default parameters.

Parameters:

name - The atomic subordinate name to open.

accessor - The accessor object that will be called to open the stream.

Throws:

java.io.IOException - When an I/O error occurs.

NoSubordinateAccessException - If the accessor does not support opening a subordinate access, for example, a file.

InputStreamNotSupportedException - If the accessor does not support an input stream.

                 throws java.io.IOException

Constructs an NFileInputStream object in the subordinate input stream with the openFlags parameter.

Given an openFlags, opens a subordinate input stream through the specified DataAccessable object.

Parameters:

name - The atomic subordinate name to open.

accessor - The accessor object that will be called to open the stream.

openFlags - The flags that are used in opening the stream in different modes.

Throws:

java.io.IOException - When an I/O error occurs.
