Member Function Documentation

virtual functor* lti::ascii85Codec::clone

(

)

const [virtual]

returns a pointer to a clone of this functor.

Implements lti::functor.

ascii85Codec& lti::ascii85Codec::copy

(

const ascii85Codec &

other

)

copy data of "other" functor.

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::dataCodec.

virtual bool lti::ascii85Codec::decodeImplementation	(	const buffer &	src,
		buffer &	dest,
		int	nsrc,
		int &	ndest
	)			const [protected, virtual]

Implementation of on-copy data decoder.

This method must not, under no circumstances, resize the destination vector.

Returns:

true if the decoding could be performed successfully.

Parameters:

	src	the source of the data.
	dest	the destination for the decoded data.
	nsrc	tells how many elements of the src vector must be decoded.
	ndest	tells how many elements of the destination vector can be used for the decoded data. When the method returns, this value tells how many elements were actually used, or notEnoughSpace if not enough elements were available.

Implements lti::dataCodec.

virtual bool lti::ascii85Codec::encodeImplementation	(	const buffer &	src,
		buffer &	dest,
		int	nsrc,
		int &	ndest
	)			const [protected, virtual]

Implementation of on-copy data encoder.

This method must not, under no circumstances, resize the destination vector.

Returns:

true if the decoding could be performed successfully.

Parameters:

	src	the source of the data.
	dest	the destination for the encoded data.
	nsrc	tells how many elements of the src vector must be decoded.
	ndest	tells how many elements of the destination vector can be used for the decoded data. When the method returns, this value tells how many elements were actually used, or notEnoughSpace if not enough elements were available.

Implements lti::dataCodec.

virtual int lti::ascii85Codec::estimateDecodedSize

(

int

originalSize

)

const [virtual]

Computes the default buffer size for decoded data.

The source of the original data buffer is given as argument. The default is to return the given value.

Parameters:

originalSize

the size of the data buffer to be decoded

Returns:

the estimated size of the encoded data.

Reimplemented from lti::dataCodec.

virtual int lti::ascii85Codec::estimateEncodedSize

(

int

originalSize

)

const [virtual]

Computes the default buffer size for encoded data.

The source of the original data buffer is given as argument. The default is to return the given value.

Parameters:

originalSize

the size of the data buffer to be encoded

Returns:

the estimated size of the encoded data.

Reimplemented from lti::dataCodec.

virtual const char* lti::ascii85Codec::getTypeName

(

)

const [virtual]

returns the name of this type ("ascii85Codec")

Reimplemented from lti::dataCodec.

ascii85Codec& lti::ascii85Codec::operator=

(

const ascii85Codec &

other

)

alias for copy member

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::dataCodec.
