The Path objects are obtained as if by resolving the name of the directory entry against dir. When an implementation supports operations on entries in the directory that execute in a race-free manner then the returned directory stream is a SecureDirectoryStream.

The entries returned by the iterator are filtered by matching the String representation of their file names against the given globbing pattern. For example, suppose we want to iterate over the files ending with ".

The entries returned by the iterator are filtered by the given filter. Where the filter terminates due to an uncaught error or runtime exception then it is propagated to the hasNext or next method.

Suppose we want to iterate over the files in a directory that are larger than 8K. The check for the existence of the file and the creation of the new file if it does not exist are a single operation that is atomic with respect to all other filesystem activities that might affect the directory.

The attrs parameter is optional file-attributes to set atomically when creating the file. Each attribute is identified by its name. If more than one attribute of the same name is included in the array then all but the last occurrence is ignored.

The check for the existence of the file and the creation of the directory if it does not exist are a single operation that is atomic with respect to all other filesystem activities that might affect the directory.

The createDirectories method should be used where it is required to create all nonexistent parent directories first.

The attrs parameter is optional file-attributes to set atomically when creating the directory. Unlike the createDirectory method, an exception is not thrown if the directory could not be created because it already exists. The attrs parameter is optional file-attributes to set atomically when creating the nonexistent directories.

Each file attribute is identified by its name. If this method fails, then it may do so after creating some, but not all, of the parent directories.

If dir is not an absolute path then its toAbsolutePath may need to be invoked to get its absolute path. The resulting Path is associated with the same FileSystem as the given directory.

The details as to how the name of the file is constructed is implementation dependent and therefore not specified. Where possible the prefix and suffix are used to construct candidate names in the same manner as the File.
