getFileFormat()

public FileFormat getFileFormat()

Gets the file format that specified in current Save/Load option.

Returns: FileFormat - the file format that specified in current Save/Load option.

getFileName()

public String getFileName()

The file name of the exporting/importing scene. This is optional, but useful when serialize external assets like OBJ’s material.

Returns: java.lang.String - The file name of the exporting/importing scene. This is optional, but useful when serialize external assets like OBJ’s material.

getFileSystem()

public FileSystem getFileSystem()

Allow user to handle how to manage the external dependencies during load/save.

Returns: FileSystem - Allow user to handle how to manage the external dependencies during load/save. Example: The default FileSystem is LocalFileSystem, it is not safe in environment like server side, But you can override the file system access by specifying a different implementation. Aspose.3D provides different FileSystem implementation like:
