C# Класс ESRI.ArcGIS.Client.Toolkit.DataSources.Kml.Zip.ZlibCodec

Encoder and Decoder for ZLIB (IETF RFC1950 and RFC1951).
This class compresses and decompresses data according to the Deflate algorithm documented in RFC1950 and RFC1951.

Открытые методы

Метод Описание
EndInflate ( ) : int

Ends an inflation session.

Call this after successively calling Inflate(). This will cause all buffers to be flushed. After calling this you cannot call Inflate() without a intervening call to one of the InitializeInflate() overloads.

Inflate ( int f ) : int

Inflate the data in the InputBuffer, placing the result in the OutputBuffer.

You must have set InputBuffer and OutputBuffer, NextIn and NextOut, and AvailableBytesIn and AvailableBytesOut before calling this method.

InitializeInflate ( ) : int

Initialize the inflation state.

It is not necessary to call this before using the ZlibCodec to inflate data; It is implicitly called when you call the constructor.

InitializeInflate ( bool expectRfc1950Header ) : int

Initialize the inflation state with an explicit flag to govern the handling of RFC1950 header bytes.

By default, the RFC1950 header is expected. If you want to read a zlib stream you should specify true for expectRfc1950Header. If you have a deflate stream, you will want to specify false. It is only necessary to invoke this initializer explicitly if you want to specify false.

InitializeInflate ( int windowBits ) : int

Initialize the ZlibCodec for inflation, with the specified number of window bits.
InitializeInflate ( int windowBits, bool expectRfc1950Header ) : int

Initialize the inflation state with an explicit flag to govern the handling of RFC1950 header bytes.

If you want to read a zlib stream you should specify true for expectRfc1950Header. If you have a deflate stream, you will want to specify false.

SetDictionary ( byte dictionary ) : int

Set the dictionary to be used for either Inflation or Deflation.
SyncInflate ( ) : int

I don't know what this does!
ZlibCodec ( ) : System

Create a ZlibCodec.

If you use this default constructor, you will later have to explicitly call InitializeInflate() or InitializeDeflate() before using the ZlibCodec to compress or decompress.

Initialize the ZlibCodec for inflation, with the specified number of window bits.
public InitializeInflate ( int windowBits ) : int
windowBits int The number of window bits to use. If you need to ask what that is, /// then you shouldn't be calling this initializer.

Описание свойств

AvailableBytesIn публичное свойство

The number of bytes available in the InputBuffer, starting at NextIn.
Generally you should set this to InputBuffer.Length before the first Inflate() or Deflate() call. The class will update this number as calls to Inflate/Deflate are made.
public int AvailableBytesIn
Результат int

AvailableBytesOut публичное свойство

The number of bytes available in the OutputBuffer, starting at NextOut.
Generally you should set this to OutputBuffer.Length before the first Inflate() or Deflate() call. The class will update this number as calls to Inflate/Deflate are made.
public int AvailableBytesOut
Результат int
