Detailed Description

The Base64 decoder class.

Member Function Documentation

GetDecodedLength()

UInt64 Murl::Util::Base64Decoder::GetDecodedLength	(	const void *	dataIn,
		UInt64	byteSizeIn
	)		const

Compute the Base64 decoded length.

Parameters

dataIn	Pointer to the Base64 source memory block.
byteSizeIn	The byte size of the source memory block.

Returns

The number of bytes required for decoding.

IsBase64()

Bool Murl::Util::Base64Decoder::IsBase64	(	const void *	dataIn,
		UInt64	byteSizeIn
	)		const

Check if a memory block is Base64 encoded.

Parameters

dataIn	Pointer to the Base64 source memory block.
byteSizeIn	The byte size of the source memory block.

Returns

true if the memory block is Base64 encoded.

Decode()

UInt64 Murl::Util::Base64Decoder::Decode	(	const void *	dataIn,
		UInt64	byteSizeIn,
		void *	dataOut,
		UInt64	byteSizeOut
	)

Decode Base64 characters from a memory block.

Decoding can be called sequential for divided source blocks.

Parameters

dataIn	Pointer to the source memory block.
byteSizeIn	The byte size of the source memory block.
dataOut	Pointer to the destination memory block.
byteSizeOut	The byte size of the destination memory block.

Returns

The number of bytes written into destination.

DecodeValue()

Char Murl::Util::Base64Decoder::DecodeValue

(

Char

charIn

)

const

Decode a Base64 character to the 6-bit value.

Parameters

charIn

The Base64 character to decode.

Returns

The corresponding 6-bit value or -1 if the character is invalid.
