Constructor Detail

Ascii

private Ascii(DataFrame mainFrame,
              java.io.File file,
              com.sun.media.jai.codec.FileSeekableStream stream,
              double[][] aad)

The private constructor can only be called from the static open method.

Parameters:

mainFrame - the DataFrame attempting to open a file

file - the file to open

stream - the file input stream

aad - the x and y data arrays

Method Detail

getPanel

public APanel getPanel()

Overrides:

getPanel in class AFile

open

public static boolean open(DataFrame dataFrame,
                           java.io.File file)

Attempt to open a file as ASCII data. For this to succeed, the data must be arranged columns of numbers. Space, comma, or tab delimiters may be used. Column 1 defines X values and remaining columns define Y values. The first line in the file may optionally contain two strings defining the units for each set of values (X first, followed by Y).

Parameters:

dataFrame - the ADAPT data frame attempting to open the file

file - the file to open

Returns:

true if successful, false if not

parseTokens

private static java.util.ArrayList parseTokens(java.lang.String $Text,
                                               java.util.ArrayList alTokens)

Check a string for space, comma, and tab delimeters, then return all parsed tokens in an ArrayList

read

public int read()

For this implementation of ASCII input, a single scan is read in at startup. Other scans that may be present are ignored.

Returns:

zero (0)

readDelimitedText

public static double[][] readDelimitedText(java.io.InputStream inputStream)

Attempt to ready x, y data from an input stream. Strings will be read until a format error occurs, or until EOF.

Parameters:

inputStream - the stream to read from

Returns:

a [][] array of doubles

readDelimitedText

private static double[][] readDelimitedText(com.sun.media.jai.codec.SeekableStream seekableStream)

Attempt to ready x,y data from an input stream. Strings will be read until a format error occurs, or until EOF. The first column is interpreted as x data, and all remaining columns are interpreted as y data.

Parameters:

seekableStream - the stream to read from

Returns:

a [][] array of doubles
