Detailed Description

Implements the common functionality needed for all ChecksumGenerators

Constructor & Destructor Documentation

DotZLib.ChecksumGeneratorBase.ChecksumGeneratorBase ( )

inline

Initializes a new instance of the checksum generator base - the current checksum is set to zero

Definition at line 31 of file ChecksumImpl.cs.

DotZLib.ChecksumGeneratorBase.ChecksumGeneratorBase ( uint  initialValue )

inline

Initializes a new instance of the checksum generator basewith a specified value

Parameters

initialValue

The value to set the current checksum to

Definition at line 40 of file ChecksumImpl.cs.

Member Function Documentation

void DotZLib.ChecksumGeneratorBase.Reset ( )

inline

Resets the current checksum to zero

Implements DotZLib.ChecksumGenerator.

Definition at line 48 of file ChecksumImpl.cs.

abstract void DotZLib.ChecksumGeneratorBase.Update ( byte[]  data, int  offset, int  count  )

pure virtual

Updates the current checksum with part of an array of bytes

Parameters

data	The data to update the checksum with
offset	Where in data to start updating
count	The number of bytes from data to use

Exceptions

ArgumentException	The sum of offset and count is larger than the length of data
NullReferenceException	data is a null reference
ArgumentOutOfRangeException	Offset or count is negative.

All the other Update methods are implmeneted in terms of this one. This is therefore the only method a derived class has to implement

Implements DotZLib.ChecksumGenerator.

Implemented in DotZLib.AdlerChecksum, and DotZLib.CRC32Checksum.

void DotZLib.ChecksumGeneratorBase.Update ( byte[]  data )

inline

Updates the current checksum with an array of bytes.

Parameters

data	The data to update the checksum with

Implements DotZLib.ChecksumGenerator.

Definition at line 72 of file ChecksumImpl.cs.

void DotZLib.ChecksumGeneratorBase.Update ( string  data )

inline

Updates the current checksum with the data from a string

Parameters

data	The string to update the checksum with

The characters in the string are converted by the UTF-8 encoding

Implements DotZLib.ChecksumGenerator.

Definition at line 82 of file ChecksumImpl.cs.

void DotZLib.ChecksumGeneratorBase.Update ( string  data, Encoding  encoding  )

inline

Updates the current checksum with the data from a string, using a specific encoding

Parameters

data	The string to update the checksum with
encoding	The encoding to use

Implements DotZLib.ChecksumGenerator.

Definition at line 92 of file ChecksumImpl.cs.

Member Data Documentation

uint DotZLib.ChecksumGeneratorBase._current

protected

The value of the current checksum

Property Documentation

uint DotZLib.ChecksumGeneratorBase.Value

get

Gets the current checksum value
