Detailed Description

Analogously to class wxString, this class wraps wxInputStream. Anatomy: This inherits from wx.Object and is, thus, a wx.NET wrapper class. Constructors either are required by wx.Object to implement the FindObject service or they pass a System.IO.Stream. This instance then serves as a wxWidgets fassade to the stream that you originally provided. On instance creation, this instance sets callback to implement a wxInputStream using the framework stream as source.

However, instances of this class may occur in another state: Without a framework stream as source. In that case, the instance simply wrapps a fully functional wxWidgets input stream without setting callbacks.

Constructor & Destructor Documentation

wx.FileSys.wxInputStreamWrapper.wxInputStreamWrapper

(

Stream

src

)

Generates a new wxWidgets wxInputStream instance whose basic functions refer to methods of src.

wx.FileSys.wxInputStreamWrapper.wxInputStreamWrapper

(

IntPtr

wxObject

)

Generates an instance wrapping a fully functional wxWidgets wxInputStream.

---

Member Function Documentation

override void wx.FileSys.wxInputStreamWrapper.Dispose

(

)

[virtual]

Reimplemented from wx.Object.

long wx.FileSys.wxInputStreamWrapper.GetLength

(

)

In contrast to property Length this does not throw exceptions but returns -1.

int wx.FileSys.wxInputStreamWrapper.Read	(	byte[]	buffer,
		int	offset,
		int	count
	)

long wx.FileSys.wxInputStreamWrapper.Seek	(	long	offset,
		SeekOrigin	origin
	)

This is not supported.

---

Property Documentation

bool wx.FileSys.wxInputStreamWrapper.CanRead [get]

bool wx.FileSys.wxInputStreamWrapper.CanSeek [get]

This returns whether a seek operation failed in the past or the wrapped stream does not provide a current position.

long wx.FileSys.wxInputStreamWrapper.Length [get]

This is not supported.

long wx.FileSys.wxInputStreamWrapper.Position [get, set]

This will throw an NotSupportedException iff the wrapped wxInputStream does not support the analogous operation.

Stream wx.FileSys.wxInputStreamWrapper.Src [get]

This is the C# stream that is used as data source. Depending of the mode of this implementation this may either be a standard System.IO.Stream providing data for an internal wxInputStream or an instance of class wxInputStream wrapping a wxWidgets input stream.
