Method Summary

PvDisplayOption	getDisplayOption() Get display options which some parsers and geometry file formats supply.
boolean	isAnimation() Determine if currently loaded data is an animation.
PgJvxSrc[]	read(java.io.BufferedReader in) Read a geometry file and return an array of new geometries.
void	setAnimation(boolean flag) Set flag whether current geometry data is an animation.
void	setDisplayOption(PvDisplayOption option) Set the display options to be saved within the geometry file.

Method Detail

read

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

Read a geometry file and return an array of new geometries.

The returned array of geometry may contain keyframes of an animation. This is checked with the method isAnimation().

Parameters:

in - BufferedReader to read textual data from.

Returns:

Array of JVX geometries.

#write(Writer)

write

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

Write an array of geometries into an output stream writer.

Parameters:

writer - Write all data to this stream

geom - Array with geometries to save

Returns:

true on success.

#read(PgGeometry [], BufferedReader)

getDisplayOption

public PvDisplayOption getDisplayOption()

Get display options which some parsers and geometry file formats supply. Note, not all geometry file formats support saving of display option.

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. Note, not all geometry file formats support saving of display option.

isAnimation

public boolean isAnimation()

Determine if currently loaded data is an animation.

setAnimation

public void setAnimation(boolean flag)

Set flag whether current geometry data is an animation.
