Method Detail

read

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

Read a WRL 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().

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.

write

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

Write an array of geometries into an output stream writer.

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
