Remarks

A DirectoryStream that defines operations on files that are located relative to an open directory. A SecureDirectoryStream is intended for use by sophisticated or security sensitive applications requiring to traverse file trees or otherwise operate on directories in a race-free manner. Race conditions can arise when a sequence of file operations cannot be carried out in isolation. Each of the file operations defined by this interface specify a relative path. All access to the file is relative to the open directory irrespective of if the directory is moved or replaced by an attacker while the directory is open. A SecureDirectoryStream may also be used as a virtual <em>working directory</em>.

A SecureDirectoryStream requires corresponding support from the underlying operating system. Where an implementation supports this features then the DirectoryStream returned by the Files#newDirectoryStream newDirectoryStream method will be a SecureDirectoryStream and must be cast to that type in order to invoke the methods defined by this interface.

In the case of the default java.nio.file.spi.FileSystemProvider provider, and a security manager is set, then the permission checks are performed using the path obtained by resolving the given relative path against the original path of the directory (irrespective of if the directory is moved since it was opened).

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

Close()	Closes this stream and releases any system resources associated with it. (Inherited from ICloseable)
DeleteDirectory(Object)	Deletes a directory.
DeleteFile(Object)	Deletes a file.
Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
ForEach(IConsumer)	Performs the given action for each element of the `Iterable` until all elements have been processed or the action throws an exception. (Inherited from IIterable)
GetFileAttributeView(Class)	Returns a new file attribute view to access the file attributes of this directory.
GetFileAttributeView(Object, Class, LinkOption[])	Returns a new file attribute view to access the file attributes of this directory.
Iterator()	Returns the iterator associated with this `DirectoryStream`. (Inherited from IDirectoryStream)
Move(Object, ISecureDirectoryStream, Object)	Move a file from this directory to another directory.
NewByteChannel(Object, ICollection<IOpenOption>, IFileAttribute[])	Opens or creates a file in this directory, returning a seekable byte channel to access the file.
NewDirectoryStream(Object, LinkOption[])	Opens the directory identified by the given path, returning a `SecureDirectoryStream` to iterate over the entries in the directory.
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
Spliterator()	Creates a `Spliterator` over the elements described by this `Iterable`. (Inherited from IIterable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)
GetJniTypeName(IJavaPeerable)
ToEnumerable(IIterable)
ToEnumerable<T>(IIterable)
