文件系统

Inheritance: java.lang.Object

All Implemented Interfaces: java.io.Closeable

public abstract class FileSystem implements Closeable

文件系统封装。Aspose.3D 将使用它来读取/写入依赖项。Example: 以下代码展示了如何导入文件，并在给定目录中提供依赖文件

var inputFile = "input.fbx";
     var format = FileFormat.detect(inputFile);
     //create a load options instance and specify a zip file system
     var opt = format.createLoadOptions();
     opt.setFileSystem(new LocalFileSystem("textures/"));
     //load the file
     var scene = Scene.fromFile(inputFile, opt);

FileSystem()

public FileSystem()

释放文件系统并释放其资源。

createDummyFileSystem()

public static FileSystem createDummyFileSystem()

创建一个虚拟文件系统，读取/写入操作为虚拟操作。

Returns: FileSystem - A dummy file system Example: The following code shows how to export file to memory, and ignore all dependent file generation.

//create a scene with material
     Scene scene = new Scene();
     scene.getRootNode().createChildNode(new Box()).setMaterial(new LambertMaterial());
     //create a save option and specify the file system, so the dependent file will be written to memory
     var opt = FileFormat.WAVEFRONTOBJ.createSaveOptions();
     var dfs = FileSystem.CreateDummyFileSystem();
     opt.setFileSystem(dfs);
     //obj's material file name is associated with the obj's file name, so we need a explicit name.
     opt.setFileName("test.obj");
     try (var ms = new MemoryStream())
     {
         scene.save(ms, opt);
     }

createLocalFileSystem(String directory)

public static FileSystem createLocalFileSystem(String directory)

初始化一个新的 FileSystem，仅访问本地目录。此 FileSystem 实例上的所有文件读取/写入将映射到指定目录。

Parameters:

参数类型描述
目录java.lang.String将您物理文件系统中的目录用作虚拟根目录。

Returns: FileSystem - A new instance of file system to provide local file access

createMemoryFileSystem()

public static FileSystem createMemoryFileSystem()

创建一个基于内存的文件系统，将读取/写入操作映射到内存。

Returns: FileSystem - A memory-based file system Example: The following code shows how to export file to memory, includes the dependent file by using MemoryFileSystem.

//create a scene with material
     Scene scene = new Scene();
     scene.getRootNode().createChildNode(new Box()).setMaterial(new LambertMaterial());
     //create a save option and specify the file system, so the dependent file will be written to memory
     var opt = FileFormat.WAVEFRONTOBJ.createSaveOptions();
     var mfs = new HashMap<String, MemoryStream>();
     opt.setFileSystem(FileSystem.createMemoryFileSystem(mfs));
     //obj's material file name is associated with the obj's file name, so we need a explicit name.
     opt.setFileName("test.obj");
     try (var ms = new MemoryStream())
     {
         scene.save(ms, opt);
     }
     //the test.obj was written to variable ms, and we can also get the test.mtl file content by
     var materialFile = mfs.get("test.mtl");

createMemoryFileSystem(HashMap<String,MemoryStream> files)

public static FileSystem createMemoryFileSystem(HashMap<String,MemoryStream> files)

创建一个基于内存的文件系统，将读取/写入操作映射到内存。

Parameters:

参数类型描述
文件java.util.HashMap<java.lang.String,com.aspose.threed.MemoryStream>这允许您读取/写入虚拟文件。

Returns: FileSystem - A memory-based file system Example: The following code shows how to export file to memory, includes the dependent file by using MemoryFileSystem.

//create a scene with material
     Scene scene = new Scene();
     scene.getRootNode().createChildNode(new Box()).setMaterial(new LambertMaterial());
     //create a save option and specify the file system, so the dependent file will be written to memory
     var opt = FileFormat.WAVEFRONTOBJ.createSaveOptions();
     var mfs = new HashMap<String, MemoryStream>();
     opt.setFileSystem(FileSystem.createMemoryFileSystem(mfs));
     //obj's material file name is associated with the obj's file name, so we need a explicit name.
     opt.setFileName("test.obj");
     try (var ms = new MemoryStream())
     {
         scene.save(ms, opt);
     }
     //the test.obj was written to variable ms, and we can also get the test.mtl file content by
     var materialFile = mfs.get("test.mtl");
