Constructor Detail

PgMapleLoader

public PgMapleLoader()

Method Detail

getDisplayOption

public PvDisplayOption getDisplayOption()

Get display options which some parsers and geometry file formats supply. Currently, this loader does not support loading/saving of display options.

Specified by:

getDisplayOption in interface PgLoaderIf

setDisplayOption

public void setDisplayOption(PvDisplayOption option)

Set the display options to be saved within the geometry file. This method must be called before writing the geometry. Currently, this loader does not support loading/saving of display options.

Specified by:

setDisplayOption in interface PgLoaderIf

isAnimation

public boolean isAnimation()

Determine if currently loaded data is an animation.

Specified by:

isAnimation in interface PgLoaderIf

setAnimation

public void setAnimation(boolean flag)

Set flag whether current geometry data is an animation.

Specified by:

setAnimation in interface PgLoaderIf

read

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

Read geometry file in Maple graphic file format.

read

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

Read Maple graphics data.

Specified by:

read in interface PgLoaderIf

Following copied from interface: jv.loader.PgLoaderIf

Parameters:

in - BufferedReader to read textual data from.

Returns:

Array of JVX geometries.

#write(Writer)

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 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.

Specified by:

write in interface PgLoaderIf

Parameters:

writer - Write all data to this stream

geomArr - Array with geometries to save

Returns:

true on success.
