C++ FileHandle::toString方法代码示例

/** Copies this file or directory to the specified file or directory. If this handle is a file, then 1) if the destination is a
* file, it is overwritten, or 2) if the destination is a directory, this file is copied into it, or 3) if the destination
* doesn't exist, {@link #mkdirs()} is called on the destination's parent and this file is copied into it with a new name. If
* this handle is a directory, then 1) if the destination is a file, GdxRuntimeException is thrown, or 2) if the destination is
* a directory, this directory is copied recursively into it as a subdirectory, overwriting existing files, or 3) if the
* destination doesn't exist, {@link #mkdirs()} is called on the destination and this directory is copied recursively into it
* as a subdirectory.
* @throw GdxRuntimeException if the destination file handle is a {@link FileType#Classpath} or {@link FileType#Internal} file,
*        or copying failed. */
