Detailed Description

template<typename ByteOrder>
class odc::codec::CodecChars< ByteOrder >

Note: CodecChars is only used as an intermediate codec. It encodes data during the normal Writer phase that is then reencoded using Int16String,... We should NEVER see 'chars' in the output data.

Member Function Documentation

◆ clone()

template<typename ByteOrder >

std::unique_ptr< core::Codec > odc::codec::CodecChars< ByteOrder >::clone

overrideprotectedvirtual

Creates a clone of this codec. NOTE: the clone is not really usefull for coding/decoding, but has the same stats/missing values as the original codec, which can be useful sometimes.

Reimplemented from odc::core::Codec.

Reimplemented in odc::codec::IntStringCodecBase< ByteOrder, InternalCodec >, odc::codec::IntStringCodecBase< ByteOrder, CodecInt8< ByteOrder, int64_t > >, and odc::codec::IntStringCodecBase< ByteOrder, CodecInt16< ByteOrder, int64_t > >.

◆ encode()

template<typename ByteOrder >

unsigned char * odc::codec::CodecChars< ByteOrder >::encode	(	unsigned char *	p,
		const double &	d
	)

overrideprivatevirtual

n.b. Yes this is ugly. This is a hack into the existing API - and it assumes that the double& provided actually is the first element of a longer string.
