Class PgMapleLoader

java.lang.Object

jv.loader.PgAbstractLoader

jv.loader.PgMapleLoader

All Implemented Interfaces:

PgLoaderIf

public final class PgMapleLoader
extends PgAbstractLoader

Loader for Maple plots which were exported from Maple using JavaViewLib or direct export techniques provides by Maple.

This loader carefully reads most Maple graphics properties and converts them to JavaView equivalent representation.

The MPL format supported by this loader work bi-directional and can, for example, be re-imported into Maple as Maple plot.

Parsing of some properties like label fonts or axes tickmarks may not be implemented yet.

public PgMapleLoader()

Method Detail

getAnimations

public PgJvxSrc[][] getAnimations()

Retrieve the previously loaded animations.

This method may be called after successful parsing an input stream with the method load(BufferedReader) and if isAnimation() returns true.

Specified by:

getAnimations in interface PgLoaderIf

Overrides:

getAnimations in class PgAbstractLoader

Returns:

Double array of JVX geometries.

See Also:

PgAbstractLoader.load(BufferedReader)

Author:

Konrad Polthier

Version:

21.08.02, 1.00 created (kp)

read

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

Read geometry file in Maple graphic file format.

21.08.00, 1.00 revised (kp)
21.08.00, 1.00 created (kp)

read

public PgJvxSrc[] read(java.io.BufferedReader in)

Read Maple graphics data.

Alternatively, one may call load(BuffereredReader) followed by getGeometries() resp. getAnimations() to have a finer control about which information one wants to use from a source. For example, optional display information must be retrieve by a subsequent call getDisplayOption() if available.

Specified by:

read in interface PgLoaderIf

Overrides:

read in class PgAbstractLoader

Parameters:

in - BufferedReader to read textual data from.

Returns:

Array of JVX geometries.

PgAbstractLoader.write(Writer, PgJvxSrc [])

write

public boolean write(java.io.Writer writer,
                     PgJvxSrc[] geomArr)
              throws java.io.IOException

Write an array of geometries into an output stream writer in Maple PLOT/PLOT3D file format, called MPL.

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

Specified by:

write in interface PgLoaderIf

Overrides:

write in class PgAbstractLoader

Parameters:

writer - Write all data to this stream

geomArr - Array with geometries to save

Returns:

true on success.

Throws:

java.io.IOException
