Method Detail

read

public BoundarySource3D read(String type,
                             File in,
                             DoublePrecisionContext precision)

Read a 3D model represented as a BoundarySource3D from the given file.

Specified by:

read in interface ModelIOHandler

Parameters:

type - the model file type

in - file to read

precision - precision context to use in model construction

Returns:

a 3D model represented as a boundary source

read

public BoundarySource3D read(String type,
                             InputStream in,
                             DoublePrecisionContext precision)

Read a 3D model represented as a BoundarySource3D from the given input stream. The input stream is closed before method return.

Specified by:

read in interface ModelIOHandler

Parameters:

type - the model input type

in - input stream

precision - precision context to use in model construction

Returns:

a 3D model represented as a boundary source

write

public void write(BoundarySource3D model,
                  String type,
                  File out)

Write the model to the file using the specified file type.

Specified by:

write in interface ModelIOHandler

Parameters:

model - model to write

type - the model file type

out - output file

write

public void write(BoundarySource3D model,
                  String type,
                  OutputStream out)

Write the model to the given output stream, using the specified model type. The output stream is closed before method return.

Specified by:

write in interface ModelIOHandler

Parameters:

model - model to write

type - the model file type

out - output stream

readInternal

protected abstract BoundarySource3D readInternal(String type,
                                                 InputStream in,
                                                 DoublePrecisionContext precision)
                                          throws IOException

Internal class used to read a model. IOExceptions thrown from here are wrapped in UncheckedIOExceptions.

Parameters:

type - model type; guaranteed to be supported by this instance

in - input stream

precision - precision context used to construct the model

Returns:

3D model

Throws:

IOException - if an IO operation fails

writeInternal

protected abstract void writeInternal(BoundarySource3D model,
                                      String type,
                                      OutputStream out)
                               throws IOException

Internal class used to write a model. IOExceptions thrown from here are wrapped in UncheckedIOExceptions.

Parameters:

model - model to write

type - model type; guaranteed to be supported by this instance

out - input stream

Throws:

IOException - if an IO operation fails
