Field Detail

m_bAnimation

protected static boolean m_bAnimation

Flag is true whenever an animation has been parsed. Each read() method must set it to false initially to initialize from previous settings.

Constructor Detail

PgMapleLoader

public PgMapleLoader()

Method Detail

isAnimation

public static boolean isAnimation()

Determine whether previous read() command loaded an animation.

read

public static PgJvxSrc[] read(java.lang.String fileName)

Read geometry file in Maple graphic file format.

read

public static PgJvxSrc[] read(java.io.BufferedReader bufReader)

Read Maple graphics data.

parseMaple

protected static java.util.Vector parseMaple(java.io.BufferedReader bufReader)

Parse the Maple graphics given in the input bufferedReader.

Parameters:

bufReader - a reader ready with data.

Returns:

Vector with PgJvxSrc geometries, or null if failure.

readGraphics

protected static java.util.Vector readGraphics(java.io.StreamTokenizer st,
                                               int dim,
                                               java.util.Vector geomVec)
                                        throws java.io.IOException

Parse a Maple graphics object.

write

public static java.lang.String write(PgJvxSrc geom)

Write a geometry into a string in Maple PLOT/PLOT3D file format, called MPL.

Numbers with absolute value less than EPS are shown as zero. This avoids the anoying fact that double precision numbers fill the whole text area hiding the exponent, which hides their small value.
