public class PxgraphApplication

extends PlotApplication

An application that can plot data in pxgraph format. To compile and run this application, do the following:

javac -classpath ../../.. PxgraphApplication.java
java -classpath ../../.. ptolemy.plot.pxgraph.PxgraphApplication

This class uses the helper class PxgraphParser to parse command-line arguments and binary files. See that class for documentation on the formats.

Constructor Detail

PxgraphApplication

public PxgraphApplication()
                   throws java.lang.Exception

Construct a plot with no command-line arguments. It initially displays a sample plot.

Throws:

java.lang.Exception - If command line arguments have problems.

PxgraphApplication

public PxgraphApplication(java.lang.String[] args)
                   throws java.lang.Exception

Construct a plot with the specified command-line arguments.

Parameters:

args - The command-line arguments.

Throws:

java.lang.Exception - If command line arguments have problems.

PxgraphApplication

public PxgraphApplication(Plot plot,
                          java.lang.String[] args)
                   throws java.lang.Exception

Construct a plot with the specified command-line arguments and instance of plot.

Parameters:

args - The command-line arguments.

Throws:

java.lang.Exception - If command line arguments have problems.

Method Detail

main

public static void main(java.lang.String[] args)

Create a new plot window and map it to the screen.

write

public void write(java.io.OutputStream out,
                  java.lang.String dtd)

Write the current data and plot configuration to the specified stream. This method is only used for testing.

_about

protected void _about()

Display basic information about the application.

Overrides:

_about in class PlotApplication

_parseArgs

protected int _parseArgs(java.lang.String[] args)
                  throws CmdLineArgException,
                         java.io.FileNotFoundException,
                         java.io.IOException

Parse those command-line arguments that are relevant to the application only, and refer other arguments to the PxgraphParser helper class.

Overrides:

_parseArgs in class PlotApplication

Returns:

The number of arguments read.

Throws:

CmdLineArgException - If a command line argument cannot be parsed.

java.io.FileNotFoundException - If an input file cannot be found.

java.io.IOException - If there is a problem reading an input.

_read

protected void _read(java.net.URL base,
                     java.io.InputStream in)
              throws java.io.IOException

Read the specified stream. This method assumes the stream contains pxgraph-compatible binary or ascii data. If it is binary, then the -binary flag must have been specified on the command line.

Overrides:

_read in class PlotFrame

Parameters:

base - The base for relative file references, or null if there are not relative file references.

in - The input stream.

Throws:

java.io.IOException - If the stream cannot be read.

_usage

protected java.lang.String _usage()

Return a string summarizing the command-line arguments.

Overrides:

_usage in class PlotApplication

Returns:

A usage string.
